Metal plastic pipes. Metal plastic pipes in water supply systems at home: what are the pros? Installation of metal-plastic pipes with their own hands

With your own hands it will be necessary when creating water and heating engineering systems from this material.

Structural metal-plastic pipes are a compound of polymers and metal. This is a 5-layer product in which the outer and inner "shell" are made of cross-linked polyethylene, and between them is a layer of aluminum. In places of contact, the layer also provides adhesive layers.

Among the main advantages of such a design:

high corrosion resistance;
immunity to moisture and aggressive environments;
simple and quick installation;
aluminum layer allows the pipe to take any forms;
it is possible to use pipes of a wide dimensional row - from 16 to 32 mm;
universality, the ability to create a system with any fittings.

Connection schemes

The question of how to connect metal-plastic pipes can be solved using one of two connection schemes:

ConsistentWhen the entire system is connected sequentially, from one point of consumption to another.
When for each of the consumer provided in the network, its approach is performed. It is believed that this type of wiring is more convenient and economical.

IMPORTANT: Whatever the system you choose, for each instrument that consumes water, you must install your own ball valve. This will overlap the water supply point in the event of a breakdown.

The overall connection scheme always starts with cranes - high-quality capable of operating with a working pressure of up to 60 atm and heating to + 150 ° C. After them, the water metering device, a fine cleaning device, a pressure reducer, a collector, and water supply pipes to each of the installed devices are already bred from it. Filters are needed to capture pollution - sand, scale, and so on. As for the collectors, thanks to them, a uniform flow of water to each of the consuming devices is ensured.

What tool will need

Different ways to connect metal-plastic pipes with their own hands will require several devices:

Scissors for cutting pipes - necessarily high-quality so that the pipe does not deteriorate when the burrows does not arise and the upper protective polymer layer was not disturbed.
Calibrator - rectifies the "consequences" of the cut, when the wall is slightly concave inside, allows the fading of the pipes.
Adjustable key and horn keys.
Pliers and drill, roulette.
If the assembly will be used. There are mechanical or hydraulic equipment (domestic and professional, respectively).
Experder, in the case of the use of supervisory fittings.

Tool for mounting metal-plastic pipes: 1 - scissors, 2 - press clamps, 3 - Calibrator

How to connect metal-plastic pipelines

For water supply, the installation of metal-plastic pipes can be carried out with their own hands. compression or press fittings.

When compression fittings are mounted, the nut screw the nut on the disclosed turning ring. This creates pressure (two wrench), due to which a solid compression compression is formed. In this case, the metal-plastic water supply is worth mounting a single segment so that "unnecessary" connections do not occur. After all compression fittings will have to regularly tightenTo preserve the tightness of the connection.

Mounting features with press fittings

The combination of metal-plastic pipes with press fittings allows you to get dear connections - They do not need to regularly pull up, they will serve about 50 years. In addition, operating pressure up to 10 atm is allowed in the joint locations.

Important: Pipes mounted using press fittings may even pour concrete.

Compound technology does not provide welding or soldering:

Initially, cut off the pipe, strictly withstanding an angle of 90 degrees.
The edge of the pipe must be processed (remove the chamfer). This ensures the fitting of the pipe for the required diameter.
On the edge of the pipe should be put on a silence of stainless steel, and in the pipe until it stops the shaped part of the fitting.
On the sleeve you need to impose a clamp of the press, and connect the handles until you stop.

If during the installation process there is a need to bend the pipes, the use of angular fittings is not necessary. Material itself is very elastic, but it is worth apply springspreventing the pipes.

Installation of metal-plastic pipes for water supply can be carried out with their own hands. superior fittings. For this, the pipe is prepared for the connection in the standard way, after which they put on the coupling. Pre-stripped edge should be processed by expander and collapse. Then the pipe is put on the fitting fitting, clamp the sleeve in the press and move. The gap fitting acts like this: when the coupling compensates for the piece, the pipe is pressed and securely fixed. This type of connection is also inconphigra.

To the wall clips Freshing screws. In order for the markup to be performed exactly, we first place space for clips. Pipes in the bottom are inserted very easily. One click and everything is in place.

How to connect metal-plastic pipes with other materials

The combination of metal-plastic pipes with metal components is performed in the case when a partial replacement of the water pipeline is carried out or the metal-plastic pipe is connected to an old riser of metal. To fulfill the connection operation, the fitting and the calibrator are required.

Before connecting metal metal plastic pipesYou need to know that if products of different dimensions are joined, the thread is selected in accordance with the size of the cast-iron (steel) pipe, and the rest (cuff and washer) are under the dimensions of the metal-plastic pipeline.

Metal pipe sweat the passage, after which the fitting is screwed. The edge of the calibrated pipe is coming to the cone, which is already screwed to the metal. Then the nut is tightened with a horn key, very neat. The washer provides a reliable crimping of a metal-plastic pipe.

Considering the question of how to connect metal plastic pipes with polypropylene, Note that the connection to the polypropylene is made by using special threaded fittings. Such a joint can be needed in places of fastening near gas speakers, washing machines.

General rules for laying of a metal-plastic pipeline

Should be considered:

the sensitivity of the material to thermo-, mechanical loads, as well as ultraviolet - in practice, this means that the open wiring from such pipes can be done only in those places where the factors of such an impact are excluded;
if the wiring is performed in a hidden, then the hatches and removable shields must be present for convenient access to the connecting fittings (if screw type fittings);
if the laying of metal-plastic pipes is underway through building structures, they also provide a sleeve so that their inner diameter is more than the size of metal-plastic pipes by 5-10 mm - then the gap is formed to be filled with a soft material;
on the surface of the pipes, cracks and scratches should not appear on the laying - this means that the markup needs to be performed only by a soft pencil or marker.

How to repair

Before starting the repair of metal-plastic pipe, you need to install the place of the leaks, block the water supply and dry the pipe, and also clean it from fat, dust and other contaminants.

Repairs can be performed on one of the following technologies:

Bandage as a way of temporary repair. You need to take a rubber pad, attach it to the place of leaks and fix it.
To temporary methods also applies flangeIn which the rubber gasket is installed.
With the help of sealant It is possible to reliably smear the cracks and places of leakage, but this composition will also deteriorate over time.
Epoxy adhesive - They are missing the leakage section, then a layer of bandage IL X / B fabric is performed, after which is another layer of glue. The entire area should dry 11 hours, and then you can restore the water supply.

Most often, the repair is made in the joint locations, that is, in fittings. You can simply pull the connection location of the elements, but if the flow does not stop, the junction will have to dismantle. Here, the possible causes of faults are:

damage in rubber sealing rings - such elements are not repaired, but replaced;
if the pipe has an uneven cut, then it needs to be aligned and re-calibrate;
if the brass fitting body burst, the fitting is completely changed.

When installing new fittings, you can lubricate the place of the joint with silicone - it provides additional waterproofing.

Metal-plastic pipes - Montage with your own hands video

The video contains instructions for independent installation of metal-plastic pipes.

In order to mount the plumbing absolutely not necessarily to resort to expertly experts. In the article step by step, the sequence of installation of metal-plastic pipes for water pipes is described in the repairs of the bathroom. Using it, you do this work yourself.

Properties of metal-plastic pipes

For the installation of pipelines of heating and water supply systems, metal-plastic pipes are currently used everywhere. Compared to traditional steel, they possess several valuable properties, thanks to which they are most often used:

metal-plastic pipes are not rust and deposits are not formed on their inner surface;
have a long service life, manufacturers guarantee the time of operation of up to 50 years;
simple and technological installation does not require special qualifications from the artist;
a relatively low price of materials and the cost of installation.

To mount the water supply during capital repairs, the customer chose metalplastic pipes with a compound on press fittings from several alternative options.

Preparation for mounting

We come up with the configuration of the future water supply. It was decided to use collectors inexpedient. This makes the pipeline more expensive, but does not give advantage of operation. Therefore, the branching of the pipeline to individual points of the waters was decided to do with tees.

After purchasing all the necessary fittings, we laid them on the floor in the sequence as they will be connected in the pipeline. Such a "rehearsal" allowed to make sure that all fittings were purchased correctly.

For installation of the water supply, we have prepared the following tools and auxiliary materials:

Special scissors for cutting metal plates and calibrator.
Press pliers for crimping connections.
Original and gas keys.
Luck and sealing paste.

Before the installation of the pipeline in the bathroom, the necessary preparatory work was made. All the old plumbing was dismantled with the pipes, the walls were plastered with the preliminary installation of beacons. After drying the plaster in the wall, sufficiently free pipes for pipes cut through.

Installation of water pipes

The connection of pipes with press fittings includes two operations:

Cut off the pipe of the desired length with scissors. The calibrator is correcting the shape of the cut and remove the chamfer simultaneously with the outer and inner surface of the pipe.
We insert the pipe into the fitting sleeve until it stops. Through special observation holes, the front of the pipe should be visible. Tips crimp the fitting twice.

The photo shows that on the sleeve as a result of crimping two ring compression is formed.

To simplify work first collect individual parts of the water supply. For example, vehicle for the installation of the mixer, presses and attach to a special mounting bar.

Prepared pieces of the pipeline set to the corresponding place and fix it. Mounting planks are attached to the wall with the help of dowels and screws, the pipes are neatly bent and laid in the shoes.

We connect the collected parts of the water supply system into a single whole in place. The refressing tick device allows you to deploy the instrument handles in a convenient position.

We continue to consistently mount all parts of the water pipeline and we attach it to the risers of hot and cold water. For the possibility of replacing water counters and cranes in the future, the connection of the pipeline to the counter is collapsing, on American.

For all the work on the installation of the pipeline from metalplastic pipes, one and a half hours left. At the end of the installation, it was put on all water outlets of the plug, the taps were opened on the risers and left the pipeline with water under pressure for several days. The shoes did not shine to check the compounds on hermeticity. Works on the decoration of the bathroom at this time continued.

The mounted water supply was sealed: no leaks were manifested in any connection. You can fill out the shutter shutter and finish the walls of the walls with tiles.

Useful tips:

Connection on the press fittings is unbearable. In case of an error it is impossible to remake it. This case is useful to have several spare fittings.
Press pliers do not necessarily buy, they can be leased.
Metal-plastic pipes need to be bent with caution. If the wall of the pipe during bending doubts, this pipe should be replaced.
So that the pipe has not experienced under the plaster of excess stresses when heating and cooled from water is better not to lure it into the plaster directly: put the electric corrugation to the pipe. For a pipe with a diameter of 16 mm, the corrugation of 25 mm is perfect.

We hope the article will be useful for you, and you will be able to mount the pipeline from a metal-plastic pipe with a compound on the press fittings on their own.

Where to start the replacement of the water supply

Installation of pipes starts with marking. You can skip the apartment on the paper and note where the water supply will be passed. This will make sure to determine the amount of material, adapters and tees. You can do it even easier: make marking and necessary calculations directly on the walls. No need to constantly look into the drawing, everything will be right before your eyes.

Please note that the eyeliner must be double: hot and cold water. Then you can make additional taps only for cold water, for example: to the toilet or washing machine.

Important! Replacing the water supply is made immediately in the entire apartment. It will exclude that it will significantly simplify the performance of work with your own hands.

After all measurements are made, you need to prepare the necessary tools. For metal-plastic products, this set is minimal.

You will need:

Set of wrench keys (including adjustable), perforator drill and pliers.
Purchase calibrator. You will need this tool for rolling of pipes.
Special scissors. Unlike metal, plastic is quite easy to cut with her own hands, it is not even necessary to make special efforts.

After that, it is necessary to overlap the water supply. If you live in a private house, there will be no special problems, it is enough just to overlap the entrance valves. In apartment buildings will have to overlap the entire riser. Therefore, it is necessary to pre-warn the neighbors and cause plumbing. By the way, you will need a housing worker to replace the entrance valves near the apartment. If the installation can be done with your own hands, the valves must change only a professional. Then the old water supply is dismantled in the apartment and you can proceed to work.

Filters are installed immediately behind the input valves. After them, the water counters usually put. You can install them with your own hands, but the employee of the Vodokanal should be.

After that, cutting pipes are performed in accordance with the harvested drawings. To do this, you will need special scissors. Metal-plastic products consist of three layers that are connected by adhesive layer. Therefore, with such products you need to contact very carefully. Using scissors you can get the most smooth cut. When using hacksaw or other tools on sections, sharp edges can remain, which will damage rubber seals. During the pruning, the product can be deformed, it is possible to return to them in the original form using a calibrator.

The combination of metal-plastic pipes occurs with the help of fittings. Do it as follows:

The inner surface is aligned using a calibrator.
Insert the fitting.
Tighten the crimping clamp and get the nut.
Paste the end of the pipe on the other side of the fitting.
Tighten the design keys.

As you can see, the installation of the water supply does not represent a special complexity with its own hands. But there are some nuances:

Tighten fittings necessarily with two keys. One holds the fitting, others get the nut. It is necessary to do it extremely careful. Fitting compounds are rather fragile, attaching a fair force, you can damage the structure. Tighten the nut is necessary before the appearance of a characteristic cod. Not too much too much. The scenes of threaded connections are recommended for reliability to process with silicone or sealant.

In any apartment there is an angle where the pipe is just bent. Plastic is a rather flexible and elastic material, but with their own hands it is unlikely to succeed. Installation of the water supply system can be significantly simplified using a spring for flexing metal-plastic pipes. If the pipes are not in sight, their flexion will be the best option. Anyone, even the most expensive fitting, does not exclude possible leaks. At the place of bend, the pipe remains the whole that does not allow leaks in principle.

Installation of water pipes to the wall can be performed using special plumbing clips. Such clips are easily attached to any smooth surface, after which the pipe is simply inserted into the clamp. Plumbing clips are different diameters, respectively, they are suitable for any pipes. So that these devices hung on the wall smoothly, it is recommended to perform pre-markup.

On this installation of the water supply, with your own hands, can be considered completed. It remains only to carry out the flow of water in the apartment.

If you plan to install metal-plastic pipes with your own hands, you need to know exactly what you do, because the material is expensive. Consider the features of plastic pipelines, laying technology, possible methods of bending, cutting and laying, types of fasteners.

Metal-plastic designs are plastic, but you need to work with them

Characteristics of pipes from metalplastic

Metal-plastic products consist of 5 structural layers:

The inner surface of polyethylene compacted at the molecular level, or from stitched polyethylene reverses.
Adhesive layer fastening polyethylene with aluminum layer.
Aluminum layer.
The second layer of glue, fastening the aluminum element with an external coating.
Outdoor plastic coating.

In the construction of goods from metalplastic popular due to their strength. The polymer layer protects the pipeline from corrosion destruction. Aluminum consisting of a pledge of plasticity and retention of the shape during operation. When calculating the pattern, accuracy is not required. All of these characteristics in the amount allow you to carry out the operational installation of metal-plastic pipes in the design of any complexity.

Compound of metal-plastic pipe

Fittings are used to fasten the parts of different diameters, filing and branching. Depending on the type of connecting part, the bonding is carried out by crimp nuts or with the help of presses.

Press fittings are used with hidden gasket of highways

Plus the use of fittings - the presence of ready-made screws of the thread, which reduces the workflow. But the vigilance should not lose, the technology of mounting metal-plastic pipes implies a filigree neat handling of the consumable material. As a rule, the hidden gasket of the communications highway is carried out, therefore it is necessary to ensure the perfect tightness of the joints.

Note: Blank fittings with a fuzzy who went threaded. If there is no choice, the use of a shaped part with disadvantages of notches is allowed, but only if the area is "defective" threads - no more than 10% of its total surface.

High-quality helical fitting has smooth ends, perpendicular to the main product, without burrs and inaccuracies on the thread.

Preparatory work

Prepare a tool for mounting metal-plastic pipes:

calibrator and fake
adjustable or horn key (if compression fittings are used)
press ticks (if press fittings are used)

The secateur (pipeline) will provide a smooth cut line, will avoid bursowns and damage on the protective coating of products during cutting. The calibrator will help to give the part of the form, flaw to the desired diameter without deformation of the sealing. Without experience or with a shortage of time, it is recommended to use electrical instruments.

To obtain smooth ends, use pipe cutter

Before assessing metalplastic pipes, regardless of the selected type of connecting parts, prepare on a simple algorithm:

the surface of the pipes are placed on the necessary divisions;

Important: When calculating the length of the segment, consider centimeters included in the fitting.

the product is cut on the markup (operate at right angles);
if the Detail has been deformed during the process, crumple it with a caliberator (it can also remove the face inside, the outer is removed by the fake).

Pick the tool for the working diameter. If the edge of the slice is sharp, process it with a sharpened metal drill with a small diameter or a round file.

Installation with compression fittings

Compression connection is suitable for open strip

When installing pipes from metalplastic using crimp (compression) fitting, make sure that all dielectric pads and sealing rings on the tail part are available. After checking, act according to the algorithm:

Pour a protracted nut on the front of the pipe.
Fix the crimp ring.

Important: If you use a cone-shaped ring, wear from a narrow edge.

Shank with effort insert into the pipe.
Seal fastening flax with sealant or palauls.
Lock the fitting with a cape nut, tighten it by adjusting the pressure to not damage the fastener, but provide complete tightness.

Tip: Use 2 keys for reliability - one hold the fitting housing, twist the nut.

Work with press fittings

Here's how to assemble metalplastic pipes using press fittings:

Remove the face from the front of the pipe.
Treat it with a calibrator.
Install the crimp coupling.
Place the sealing rings on the fitting, insert the fitting into the pipe, the place of contact of the metal elements protect the dielectric gasket.
Insert into the press clamp inserts a diameter suitable for the fitting with a fitting, expand the tick handles by 180 °.
Place the connection in the ticks, commemorate the handles and degenerate until it stops.

Video: How to work with press fittings

Flexion and fastening of pipes

Mainstrokes are fixed from metal plastic on the walls and other surfaces with the help of special clips. Such adaptations simplify dismantling of metal-plastic pipes with their own hands if necessary.

In case of deformation of the product, the calibrator will help him

Choose clips in size and diameter of pipes.

How to fix: Install the clips with dowels and screws. So that the pipeline does not resist, install the mounting to the wall at a distance of no more than 1 m. When turning and already existing curvatures, the highway is fixed on both sides.

Bend the segment of metal plastic can be hands, with a spring, a construction dryer or pipe bender:

Manually. The product is attached to the form by pressing with hands. Suitable for experienced masters, with small diameters of pipes.
The use of spring prevents deformation (stretching, breaks, uneven bend) and simplifies work. The device is inserted into the flexible part, you can bend. Spring must match the working diameter.
Hairdryer due to heat softens plastic, the product bends into one movement. The main thing is not to overlay the material.
The perfectly smooth turn will provide pipe bending. You need to set the bend angle, insert the part in the grooves and bring the handle.

Rules for working with metal

Plastic vulnerable before UV radiation, thermal and mechanical damage. Therefore, the open installation of metal-plastic pipes for water supply or other purposes is allowed only in areas where such factors are missing. Also in the open main installation of the highway after decoration of the walls.

List of rules:

If you make a hidden highway, in the overlap, pride the hatches and removable shields without sharp edges so that there is access to the place of joints and fittings.
Do not allow the chances, cuts and breaks on the pipes. To avoid scratches, do not use sharp items when unpacking pipes.
Through the walls and other overlaps, perform a pipeline using a sleeve, the diameter of which is larger than the external girth of a pipe by 5-10 mm.
Remember: Installation of metal-plastic products can be carried out at a temperature not lower than 10 °. If consumables were at a minus temperature, allow them to warm to roommate before work.

Marking up with a pencil or marker, and metal connections equip the pads from soft materials.

You can easily handle the installation of metal-plastic structures if you follow the instructions of the manufacturer and stack patience.

Water pipes made of metal-plastic pipes - the most common option of the "wiring" of the water supply in houses and apartments. They firmly reigned in this market segment. And there is good reasons for this.

On this page, we describe all the pros and cons of such a water supply, as well as in detail, we describe how to make metal-plastic pipes, how to connect them with fittings, etc.

Advantages and disadvantages of metal-plastic water supply

There are several objective indicators that allow metal-plastic pipes to shut up for the belt of their competitors when the water supply system in an apartment or house:

Easy installation. With careful work, they can be performed by any person without any preparation. Almost this semblance of a designer, for the assembly of which expensive tools and special skills are not needed.
Reliability. Warranty 50 years ago confirmation. But note that it applies to pipes, and not on their compounds.
Price. One can say one thing: "Cheaper, just for nothing." Some competition for this parameter can be polypropylene pipes, but otherwise they lose.

Based on the foregoing, the plumbing on metal-plastic pipes is obtained reliable, it costs it inexpensively, and you can collect it with your own hands. Naturally, connecting to the central system, it is the prerogative of professionals.

No matter how regrettable, but each honey barrel, there is a spoon of tar. In the case of metal-plastic water supply, these are fittings.

Fitting, this is a device with which you can:

In our case, we are talking about metal-plastic pipes. If the fitting at both ends has the same diameter, then it is straight; And if different, then transition.

But these are only their varieties for their intended purpose, but according to the method of fixation, all fittings are divided into crimping and presses.

Crimp fittings. Differently called ring, or served. In those, the fixation is performed due to the conical shape, the inner surface, the crimp nut, which, when twisting, compresses the edge ring. Such compounds can be disassembled and they require periodic maintenance. Usually once a year, crimp fittings on metal-plastic pipes for which flows hot water, It should be checked and, if necessary, tighten a little. The reason for their weakening is the temperature deformation from hot water. For their installation, two gas (adjustable) keys are required.
Press fittings. Or non-maintained, fixed on a pipe by pressing a special crimping sleeve. Work is made by press clamp. They can be manual or electric. In the first cost from 4 TR, the second from 25 tr. The compound is obtained indefinitive, but with a guarantee from leaks, regardless of water temperature. Most often, press fittings are used in connections that will be molded into the walls, or with difficult access after repair.

Reliability and quality of compounds depend on the scrupulousness of the execution of instructions. But at the price ... Although the press fittings are cheaper than the crimp, but their total cost for the water supply equipment in the apartment is equal to the costs of metal-plastic pipes.

We plan a water pipe "on paper"

The most important and primary, this is a plan of water supply layout. If you have never been engaged in this, then you can make it up with a clean leaf without much difficulties, although this is satisfied with the painstaking. But everything starts from the consumer.

It is necessary to mark the places in which the cranes will be. This is a kitchen and a bathroom. With competent construction, they are usually located nearby, which facilitates and significantly reduces the cost of the water supply system. In the perfect version, if they are in adjoint premises, only one pipe will be required, from which the tee will be taken offen in different rooms.
The place of arrival in the house of water is designated. There are only two options: central water supply or private well (well). Depending on this, additional equipment may be required. In particular, when using water from the well, it is necessary to install a hydroaccumulator (above the level of consumers). From it, water is self-shot to enter the house. Such a system is preferable, for it does not require constant inclusion of the pump. The hydroaccumulator does not have to be metallic. It can be "pouring out" from concrete. And already in the house mounted:
Filter system (equipment depending on water quality).
Boiler.

Accordingly, that if the water flows into the house from the central water supply system, then the input will require only controlling instruments to account for consumption.

This is a schematic diagram. Give recommendations on the filtration system, not knowing the quality of water, is not permissible. Also belong to the water heating system. Depending on the conditions, the boiler can be electric or gas. The use of a water heater on liquid or hard fuel is not economical and associated with certain difficulties. Especially in the summer.

Required tools and materials

From the cranes, the bempwint is unwound along the wall. In places of bend or branching, cloves are clogged, and the direction changes. Accordingly, that from tees, two (or three) bemps will already go. By placing the entire system thus, it is necessary to draw its location not the wall. Can be chalk or water-emulsion.

Only after that, the beep must be removed, and to measure its length. Additionally calculate the number of fittings and their types.

Important: The resulting Pipe Metrah, increase by 10%. This is common practice.

Regarding the selection of the diameter of the pipe, there are already a prevailing opinion. Almost for all residential buildings and apartments, with an excessive enough metal-plastic pipes ᴓ16 mm. It provides a flow of up to 3 m 3 / hour. And most water counters are not designed for greater flow. Yes, and why more?

The choice of the manufacturer of metal plastic pipe is perhaps the most difficult task. In the market often come across fakes. Purchase a pipe in a solid store or from proven suppliers. We recommend to refrain from the purchase of metal-plastic pipes of Chinese manufacturers. Negative reviews are found too often. The highest quality metal-plastic pipes are produced in Belgium ( Henco.), Germany ( Frankische and Sanha.).

What will be required of the tools:

Cutter for metal-plastic pipe (from 250 p).
Caliber with zenker (from 200 p).
Conductor (from 500 p).
Press ticks (from 4000 r., But you can rent).
Two gas (or adjustable) keys.
A hammer.
Sculpture.

How to work with a tool

Caliber, restores the shape of the pipe after cutting, and Zenker removes the chamfer and removes burrs. If the caliber is without a zenker, then its work can be performed using shallow sandwich.

The conductor serves to flexing the metal-plastic pipe. It is external and inner. The use of internal in some cases is more convenient, for it does not slide in his hands. But it is not always possible, for the place of bending can be far from the end of the pipe. Therefore, we recommend to stay at the external conductor.

Press pliers will be required if you use maintenance-free fittings. We, on the basis of 16 years of experience, we recommend that the press fittings are recommended. And the reason here is one. Most tenants, in a year they forget about the service of crimp fittings. And this leads to leaks. But the choice is yours.

Consumables will require: self-tapping screws, fastening for metal-plastic pipes, tape FUM.

Mounting process of metal-plastic pipes

Starting the installation of metal plastic water supply is necessary from the source to the consumer (to the cranes). Make a cut from the roll to the nearest fitting, and cut it with a knife. Calibrate, remove the burrs and remove the chamfer. Then insert the pipe into the fitting until it stops. The press fittings have special holes, to control the depth. They should be visible the edge of the metal-plastic pipe. Then insert the fitting into the ticks, and crimp the connection.

Crimp fittings are fastened with nuts and rings included in the kit

It is quite simple to work with the press ticks, because insert the fitting "Crooked" will not work.

All press clamps have replaceable sponges for pipes of different diameters. Do not make mistakes in choosing sponges.

The process of installation of crimp fittings is slightly different. The nut first puts on the prepared trim, then the edged ring and after that, the pipe is inserted into the body of the fitting itself. Before spinning the nutWe strongly recommend that turning the fum ribbon. It takes only two or three turns. It is necessary to start from the edge of the thread and carry out the winding, holding the latitude tape. After that, moisten the thread with sunflower oil. This technique will protect against the appearance of leaks!

The nut is first twisted with their hands until it stops. And only then, holding the fitting with one gas key, others tighten the clamping nut. It should not be drawn out of all the might, but the small effort is needed.

Installation with press ticks

Fix the metal plastic pipe to the wall follows each meter. Special attachments through the self-sufficiency are strengthened in the surface, and the pipe is inserted into them.

In those places where it is permissible, the pipe can be bent using a conductor. To do this, the conductor dresses onto the pipe, supply it from the right place, and neatly, holding the product with his hands, on an equidistant from the target distance, bend the pipe in the desired plane. Given that the radius of the bending of the metal-plastic pipe is equal to its 8 diameters, this approach is not expedient everywhere.

Checking, leakage

By installing metal-plastic pipes, connect them to the crane with the help of hoses that are included. Then go through all the route again, and visually check the integrity of the assembly.

Pay attention to tees and splitters. Sometimes, inserted by one branch, the installer forgets about fixing the pipe in another.

Open the taps at the end of the water pipeline (in the kitchen and in the bathroom). And only after that slowly, in order to avoid a possible hydrate, open the water supply faucet to the system. It is most convenient to perform this stage with a partner. It should control the water outlet in the final point. As soon as the water went, for washing pipes, let it drag it within 2-3 minutes. Then close the outlet cranes, by this you raise the pressure in the system, and go through the pipe of the pipe gasket. Check all connections. If you doubt, do a paper napkin (or toilet paper) on the surface of the fitting connections). Do not confuse condensate with leak!

We guarantee that if you fulfilled work according to our recommendations, then in 99.9% there will be no leaks. If a connection causes you a reasonable fear, then slightly tighten it.

How to make the installation of metal-plastic pipes with their own hands

In the life of a modern person, an important place is occupied by the transfer of various substances, in particular, water, by the distance using the supply systems - pipelines, the most important and extended part of which are pipes.

Due to the wide range of products today, each host host has the opportunity to independently assemble the water supply system using products from any suitable material. This article will tell about the installation of metal-plastic pipes for water supply with their own hands, characteristics and advantages of such products.

The device of pipes from metal plastic and their advantages

Products of this type consist of three main layers and two sucks, from the inside to outward:

The layer of molecularly compacted or cross-linked polyethylene.
Glue layer between the inner layer and aluminum foil.
Aluminum layer.
The glue layer connecting aluminum and the outer layer of the polymer substance.
Outer plastic layer.

Advantages of products from this material:

relatively small, compared with metal elements, weight that makes it greatly facilitating all operations for maintenance, planned or unscheduled repair, dismantling and installing metal-plastic pipes;
lack of corrosion threats, since the inner and outer layers of products are made of plastic not destroyed under the influence of water;
thanks to the reinforcement of aluminum, the linear expansion coefficient is very low;
the consequence of the previous point is the ability to do not withstand the ideal accuracy during the calculations and preparation of products.

Among the shortcomings of metal-plastic pipes, the following can be distinguished;

their mechanical strength and resistance to overloads is still less than that of metal elements;
the upper thresholds of operating temperatures and pressure are also not so high.

A few words about the wiring of the water supply system

Wiring of metal-plastic pipes with their own hands as a whole is simple; The process begins with mounting on rising ball valves. At this stage, it is necessary to especially carefully select fittings, giving preference to high-quality products suitable for use at least 60 atm. and temperatures about 150 ° C.

It is clear that, since, for the quality of Chinese products, no one can vouch for and bring it at any time, it is best to avoid acquiring it, stopping on more expensive, but reliable versions.

Especially this is essential, if we consider that it is precisely through the ball cranes in the event of a leakage of the system overlap the flow of water into the apartment.

Selecting good cranes and installing them, you can continue to mount the plumbing from metal-plastic pipes with your own hands.

The following preparatory stages of water supply system arranged:

Installing a filter for deep cleaning and watercolor.
Installation of a filter intended for fine cleaning.
Introduction to a pressure reducer circuit.
Installation of the collector, from which the metal pipes will be discharged, connectable by various methods and subsequently connected to the instruments of the plumbing destination.

Despite the fact that the inner surface of stitched polyethylene is sufficiently resistant to the effects of small abrasive particles, the installation into the system with metal-plastic pipe filters is necessary: \u200b\u200ba large amount of sand, metal particles or pieces of scale can damage not only the pipeline, but also output devices.

The collector must be assembled to provide the same intensity to supply moisture from a common riser to all sanitary cells - sinks, washing machine and toilet bowl.

Usually in the collector is provided from two to four outputs. If there are more devices in the house in the house, it is possible to select collectors with an appropriate amount of outlet.

Fittings for metal-plastic products

The most important question that should clarify the home master is how to assemble metal-plastic pipes. Usually, special connecting elements are used for this purpose - fittings.

They are two types:

Press fittings (mounted presses).
Screw (compression type).

Mounting features with compression fittings

These products are characterized by:

the strength of the compound is ensured by the pressure of the knurable nut on an incurred crimping ring;
the lack of need to look for special tools for connecting pipes: just two wrench keys, one of which hold the place of installation, and the other tighten the crimping nut;
the need to apply with the laying of metal-plastic pipes with their own hands as little intermediate connections;
the possibility of gradually loosening the strength of the connection, as a result of which it is necessary to stretch the crimping nuts from time to time; Because of this, stacked the pipes mounted in this way in the walls or floors is not recommended.

You can avoid the last problem by replacing crimping products with press fittings.

Mounting features using press fittings

Such products are more reliable and durable (service life is at least 50 years), withstands working pressure up to 10 bar and provides ease of installation of the pipeline.

The only drawback is the need to apply a special press machine, manual or hydraulic with a microprocessor.

Sliced \u200b\u200ba piece of pipe of the desired length.
Remove the face with the ends and customize the diameter of the product.
They put on the end created from stainless steel sleeve.
Paste the prepared part of the pipe with the fitting until it stops.
The gripping of the press car take a sleeve and compress it, pulling the press handle.

For the connection to be durable, you should follow the following rules:

pipes do not tolerate ultraviolet rays and mechanical damage, so it is possible to put them in the open way only where there are no these factors (read also: "How to build metal-plastic pipes - step-by-step management of the compounds");
with a hidden gasket, it is necessary to provide access to fittings, providing for the installation of various windows and removable panels during installation;
when you need to spend pipes through the house designs, select the sleeve with a diameter, large by 5-10 mm of a similar external parameter of the pipe. The gap creates a non-combustible material, which, when squeezed, contributes to the longitudinal promotion of the pipe;
when mounting products on the walls, use the suspension and supports supplied by the same manufacturer, and the metal parts of the fasteners areolate with a soft material;
it is impossible to allow damage to the product surface.

In compliance with these tips, the assembly of the water supply system will be simple and not particularly expensive.

Installation of metal-plastic pipes: water pipes with your own hands, how to fix, gasket, water supply, installation

Installation of metal-plastic pipes with their own hands

When performing pipelines of any type of water supply today, the installation of metal-plastic pipes is successfully used.

Metal plastic pipes due to their design have a number of advantageous advantage of them from other types of similar products.

Assembling metal-plastic pipeline

The advantages and device of pipes from metalplastic

Constructively in metal-plastic pipes there are five layers:

The inner layer of the product is made of cross-linked or compacted molecular polyethylene;
The glue layer connecting the aluminum layer and polyethylene;
Aluminum layer;
The glue layer connecting the aluminum layer and the outer layer of plastic;
Layer of plastic.

Metal-plastic pipes have certain advantages relatively with similar products:

Metal-plastic pipes due to the polymer layer have high corrosion resistance.
Thanks to the layer of aluminum, the products are elastic and retain the form, whereby the installation of metal-plastic pipes of almost any complexity and configuration is possible.
Ideal accuracy in calculating linear dimensions is not required.

Features Watering Watering System

Montage with your own hands of metal-plastic pipes starts with a device of ball valves on a riser. For installation, it is necessary to choose exclusively high-quality ball valves that are capable of operating at high operating pressure (within 60 atmospheres) and a temperature of 150 degrees.

Chinese fakes should be avoided, because in the water supply system, much depends on the quality of the cranes.

It is the ball crane in a situation with the appearance of leaks, you can overlap the flow of water in the apartment.

Ball cranes for metal-plastic pipeline

Scheme of a metal-plastic pipeline system

Deep cleaning filter and water meter;
Filter of fine cleaning;
Pressure reducer;
The collector from which the layout is made and the installation of pipes from metalplastic to directly plumbing devices.

Metal plastic pipes are mounted together with filters to secure plumbing devices and the pipes themselves from small particles of sand, metals, Okalin present in risers in significant quantities.

The collector installation is required to ensure uniform water supply to consuming elements - sink, toilet bowl, washing machine, from a water rummer. As a rule, collectors have 2, 3 or 4 outputs. In the event that the number of consuming devices more than four, select such collectors that have the required number of outputs.

Pipes for pipes from metalplastic

If metal-plastic pipes are required - installation and immediately compound is performed using fittings for metal-plastic pipes, which are the following types:

Connection of pipes by compression fittings

Scheme of compression fitting

Completion with compression fittings:

In the case of applying a compression fitting, the compound is obtained by pressure occurring in the process of spinning the nut on the crimping open ring.
To perform a compression connection, special tools for mounting metal-plastic pipes are not required.

The connection is performed using two wrench: at the time when one is tightened to the nut, the other key is resistance.

If, when performing a wiring, metal-plastic pipes are used - the installation should be made to the device that consumes from the collector with one "thread", avoiding unnecessary connections.
After a while there may be a need for a broach to maintain the tightness of the compression fittings.

But if we put into the floor or close the pipes with a tile, having several fitting connections, then the performance of this operation or dismantling of metal-plastic pipes in the event of such a need to become very difficult.

To avoid periodic feeding of fittings, you will not remain anything, how to mount metalplastic pipes with press fittings.

Compound of pipes from metalplastic with press fittings

Press fittings are durable and durable (the warranty on them is up to 50 years), can withstand pressure up to 10 bar, and produced by their help of metal-plastic pipes is performed quickly and easily.

Metal-plastic pipes with compound press fittings are installed using a special press machine. This tool for mounting metal-plastic pipes is simple manual and microprocessor hydraulic.

Instructions for installing metal-plastic pipes with compound press fittings:

The pipe is cut off with special scissors at right angles.
Using a scan and a special tool for calibration, the chamfer is removed, and the pipe diameter is adjusted for the subsequent installation.
A sleeve made of stainless steel is put on the tube.
Up to the stop in the fitting pipe, the shaped part is inserted.
The pressure clamp - manual or hydraulic - the sleeve is captured.
Before the stop, the handles of the press are reduced.

Rules for laying of a metal-plastic pipeline

The pipeline from metal plastic is paved in accordance with the following rules:

By installing metal-plastic pipe, it is necessary to observe emergency accuracy, since the pipes are very sensitive to the effects of ultraviolet radiation, mechanical and thermal damage.

An open gasket of such pipes is permissible exclusively in such places where there is no impact of these factors.

Mounting technology of metal-plastic pipes with a hidden gasket provides for the device of hatches and removable shields to access compression type fittings. Such hatches and shields should not have sharp protrusions.
Installation of pipes through the designs of buildings is carried out using a sleeve with an inner diameter, by 5-10 mm exceeding the outer diameter of the pipe.

The gap that is formed at the same time is filled with a soft non-aggravated material capable of ensuring the movement of the pipe in the longitudinal direction.

During the device of metal-plastic pipes for water supply or heating at each stage, it is necessary to remember the inadmissibility of the occurrence of scratches or cuts on the surface of the pipes.

Example of a household water supply system scheme

Unpacking the bay with a pipe, do not use sharp objects. When the pipe is marked, you must use exclusively a pencil or marker.

Metal-plastic pipe installation is made by means of supports or suspensions, with which the mounting to the wall is performed.

Supports and suspensions are offered by pipe manufacturers. Metal fasteners need to be equipped with soft material gaskets.

The pipeline from the metal plastic, made by its own hands, will last longer if the tips, instructions and recommendations will be fully respected.

Installation of metal-plastic pipes with your own hands: how to assemble, which tool is needed

192) Installation of metal-plastic pipes with their own hands: a tool for installing a water supply system, how to assemble, assembly instruction, technology

Installation of metal-plastic pipes with their own hands: Compound technology + wiring examples

Modern materials for the arrangement of domestic highways made it possible to independently assemble water supply and heating systems. For example, the installation of metal-plastic pipes with their own hands allows you to arrange a tap or sewer wiring. To work with such elements, no complex tools or special skills are required.

Features of metal-plastic products

Metal-plastic (metal-polymer pipes) are composite products, for the production of which various types of materials apply. Such elements have an attractive appearance, good wear resistance, elasticity, strength.

As a rule, the pipe consists of five layers. A durable polymer is used as a carrier base, usually stitched polyethylene. It gives the smoothness of the inner surface, protecting it from blockages, and also contributes to the strength of the product.

An adhesive substance is applied to the core, on which the aluminum foil stabilizing pipe is strengthened (it also prevents oxygen intake). The connection is secured by welding online or brass.

The fourth layer is also applied with glue, to which the outer coating is connected - white polyethylene, providing the product with protection and aesthetic appearance that gives it aesthetic appearance.

Technical characteristics of pipes D 16-20 mm

We present the data characteristic of metal-plastic pipes of common diameters (16 and 20 mm):

The wall thickness is respectively 2 and 2.25 millimeters; The thickness of the aluminum layer is 0.2 and 0.24 mm.
One run-down meter weighs 115 and 170 grams and accommodates the volume of liquid equal to 1,113 and 0.201 liters.
The coefficient of thermal conductivity is 0.43 W / m to, the expansion of the metalplastic - 0.26x10 4 per 1 degree Celsius, the coefficient of roughness - 0.07.
With the transverse break of the material, the strength coefficient is 2880 H.
The adhesion strength of the adhesive layer with a foil is 70 H / 10 square meters, the strength coefficient of the aluminum welded layer - 57 H / sq. mm.
Metal-plastic pipes can even work at +95 ° C, briefly withstanding the temperature + 110-130 o C.
In the temperature boundaries from 0 to +25 o, the system functions at a pressure of up to 25 bar, and at +95 ° C withstands the pressure of 10 bar.
The tightness and integrity of the metal-plastic pipe is broken under the load of 94 bars (at +20 ° C).

With the right installation and observance of the operational rules, the product from metal-planes can serve as 50 years and more.

Advantages and disadvantages of metal-polymer

The advantages of such products can be attributed:

eastern of installation: Compounds of various categories of metal-plastic pipes are carried out quickly and easily;
high heat resistance (can be transported water heated to 100 ° C);
reasonable price (metal-polymer pipes are cheaper than metal and most plastic analogs);
high strength, ring rigidity;
corrosion resistance, aggressive environments;
no clock to the formation of sediments and blockages;
aesthetic appearance;
high bandwidth;
low thermal conductivity;
sufficient plasticity;
the possibility of light repair;
durability.

The main disadvantage of such products lies in the fact that the metal and plastic, of which they consist of pipes, have different expansion indicators. Regular temperature differences of the agent in the pipes can lead to a weakening of fasteners, which is why there are flows in the design.

To avoid this, experts advise, making installation, always provide a certain supply when joint joints. It will also be useful because metal-plastic systems are poorly withstanding the hydrowarders.

Scope of application of metal-plastic elements

Pipes made of metal-polymer are widely used in the arrangement of individual houses, in industrial construction and agriculture.

The main areas of their use are:

transportation of liquids, gaseous agents;
laying of drainage systems, water pipes, heating;
in structures involving the transfer of compressed air;
podding the components of heating to radiators, a warm-alone device;
installation of air-conditioning schemes;
protection and shielding of wires (primarily power);
the structure of watering systems.

when organizing central heating systems with an intended device of elevator nodes;
in places with a prescribed fire safety level "G";
with the intended supply of hot liquid in the pipeline with a working pressure\u003e 10 bar;
in rooms where it is planned to place the sources of thermal radiation with a surface temperature of above 150 degrees C.

In addition, metal-polymer pipes are undesirable to use in safety, signal, overflow, expansion schemes and in fireproof water pipes.

Three main ways of pipe wiring

Wiring of metal-plastic systems can be carried out by different methods, each of which is chosen on the basis of the feasibility and possibilities of further access to the system.

Option # 1: Hidden

In this case, all pipes and connections are hidden in the depth of the wall under finishing materials. Alternatively, only fittings and taps for connecting plumbing devices are displayed.

When using this method of installation, the interior design is preserved, in addition, the masking of communications protects them from random damage.

This option has several minuses:

To lay the channels for pipes, a complex and time-consuming process of sticking is required. After laying communications, the surface has to restore again.
Such a way is not suitable for bearing walls, where it is forbidden to carry out the launch of regulatory documents.
A fairly high cost associated with extension work.

This way it is better to take advantage of the repair in the bathroom. It is impractical to arrange a hidden gasket in the already decorated room, since it will take a complete dismantling of the wall covering (facing, plaster).

Option # 2: Open

If the pipes for any reason can not be covered in the wall, they can be paved along its surface. This option is more convenient for visual control over connectivity places, which allows you to quickly clean the site or replace the component.

An open layout can be used in rooms with already repaired, since the installation will not harm the design of the walls. The advantages of this method include its ease and lower cost of work than when laying internal communications.

Option # 3: Combined

In this case, the pipes are carried out on the surface of the indistened walls, after which they are closed by boxes or false panels. This is a rather complicated way, since it requires perfect fit into the interior of decorative elements, which can also use plasterboard, tiles and other materials.

Schemes for bathroom and bathroom

With plumbing works carried out in bathrooms and toilets, three layout of metal-plastic pipes can be used. For private houses, the use of the collector is the most rational.

Effective collector system

A reliable and practical option involving the connection of each object to the central tube through the entrance pair. This allows the crane to adjust or turn off the water supply to each specific plumbing.

All regulatory devices are located in a compact manifold, which is placed in the space specifically allocated to them (cabinet).

Drinking pipes that have a minimum of compounds do not require special control, which allows the gasket to be laid in a hidden way. The disadvantage of this option is quite high cost, because for each connection you will need to purchase a special shut-off crane. Since such a system is quite complicated, it is necessary to produce neatly and carefully.

An important advantage: in case of failure of a separate item (washing machine, mixer), there is no need to completely disconnect the bathroom from the water supply - it is enough to turn off the desired shut-off valve.

Sequential system of connections

This option involves the connection of each SANTEXPEDMET to the main pipe with a separate tee. It is more suitable for bathrooms with a minimum number of objects (washing machine, a common mixer).

The consistent scheme can be implemented already after completion in the room of finishing, using an open laying system. The assembly process is quite simple: the pipe is laid from one item to another, at the same time the underlining element is displayed from the tee.

This option requires minimal financial costs. It should be noted that with a large number of points for the fence of the pressure fluid may not be enough, and the system will function with difficulty or even fail.

Wiring system with passage sockets

Connecting plumbing devices is similar to consistent, but instead of tees, outlets are used. This scheme is usually applied only in individual houses, since it requires a large-length pipe laying, as well as the installation of an additional pump, which will help ensure the necessary water pressure.

When performing connecting works with metal-plastic pipes, several important nuances should be taken into account:

When developing a design, it is desirable to provide for at least connections.
It is important to apply the pipe and connecting couplings made from the same material.
For the pipeline it is better to use thermal insulation that allows preventing condensate sedimentation.
It is necessary to provide free access to the accounting devices, filters, detachable connections.

Compliance with the rules will create a reliable system capable of listening for many years.

Wiring of sewage pipes

The work on the installation of sewage metal-plastic pipes has its own features.

In this case, it is important to comply with the following requirements for the unobstructed drainage removal with blockage prevention.

To withstand a slope (0.02-0.03 from the holistic length of the design) towards the drain collector.
It is forbidden to put taps at an angle of 90 degrees when installing structures.
The need to install special tees with removable lids (revisions) in areas before turning inclined to form blocks.
When laying the system with a hidden way, it is important opposite the audit to leave viewing windows.
Collecting the system, it is important to leave a stock intended for the temperature expansion of the product.

To install sewage, it is necessary to use pipes, the diameter of which ensures easy wastewater permeability. For the toilet bowls, it is recommended to use products with a diameter of at least 100 mm, for baths and sinks - enough 50-75 mm.

Rules for installation of metal-polymer structures

When laying metal-plastic systems, it is important to be guided by the following provisions:

With a hidden laying of pipelines from this material, it is important to provide removable shields (hatches) devoid of sharp protrusions. They provide access to compression fittings.
Stacking systems through structures of buildings It is important to produce with the help of a sleeve, the inner diameter of which is 0.5-1 cm more similar to the pipe parameter. The gap that is formed between the elements must be filled with a soft non-combustible material that ensures the movement of the pipe in the longitudinal direction.
When laying metal plastic water supply or heating systems, it is important to prevent damage to the surface of the elements, including scratches or cuts. To unpack the bay, it is better to avoid sharp objects, and the design markup is performed with a pencil or a marker.
Installation of construction can be carried out using support or suspension, which are usually present in the range of metal-polymer pipe manufacturers. They help attach products to the wall, while the metal parts are installed with gaskets made of soft material.

All stages of operations need to be carried out carefully and neatly, since metal-plastic elements are sensitive to ultraviolet, mechanical damage. The outer installation of such structures is appropriate only in places where there are no similar factors.

Tools and materials for pipe gasket

For laying metal-polymer systems, minimum devices and materials are required, but it is better to choose high-quality devices and pipes.

Fixtures for mounting pipelines

To create a construction of metal-plastic, a fairly modest set of tools: pipe cut, the simplest pipe bending, sliding and precipitated keys.

Truborez is needed to separate dimensional cuts of the pipe from the bay. Since metalplastic is sufficiently supportive material, it can be cut with a metal knife or even a sharp knife. However, the perfect perpendicularity of lines, without which it is difficult to obtain a hermetic compound, can be obtained only when using a special cutter.

The keys of different species are important for installation and assembly of threaded connections on pipeline fittings. With an extreme need, you can do with one precipitant key, however, it is better to use two precipitated and one-aligned key for comfortable work.

Caliber is an important tool for creating an accurate and sealed connection of the pipe with a fitting: it allows you to center the plane of the slice and remove the champecker from the inside of the product.

The pipe bender allows you to change the configuration of the element, which can be saved on the corner fittings. It is especially important to have this tool if the design involves a large number of angular conjugations.

What materials are required

For laying the pipeline, it is important to stock in the following components:

pipes (bay, measuring segments);
various options for fittings (bypass, tees, corners), with which certain areas of pipes turn into a single system;
fasteners - folding clamps and clips, with which metal-plastic structures are fixed on support surfaces, most often on the wall.

It is important to choose all the necessary materials and tools in advance, to then freely exercise all the work.

Marking of pipeline lines

Before starting work, it is important to consider how pipes will be placed. When developing a scheme, it is desirable:

Apply the lines of the pipeline directly on the walls of the room, where it is planned to lay, which contributes to the visualization of the structure.
As the starting point, use the plug connection area to the crane or the radiator, which must already be installed before the installation.
Minimize the number of tees and crosses affecting the stability of the pressure, as well as minimize the number of other fittings.
For the corner laying of metal-plastic pipes, you can use pipe bend or corner fittings.
All connecting element should provide free access, as the fasteners on the thread need periodic pulling into order to avoid leaks.

Installation of connecting elements must be performed after the calculations and markup of the structure.

Fittings Review for Metal Flast System

To prepare for work, it is important to cut the pipes to the sections required for the length, while all the cuts should be carried out strictly at right angles. If in the process cutting the pipe is deformed, it must be aligned with a caliber (it will help to remove the internal chamfer).

For the installation of the design, various types of fasteners apply, we will stop separately.

Option # 1: collet

Collet fittings, consisting of a housing, crimp ring, rubber gasket, have a detachable design, so you can apply several times. The carving of parts allows you to combine them with household appliances.

To connect the connecting elements to the pipe, you need to wear a sequential nut and ring. Insert the resulting structure into the fitting, tighten the nut. To make the pipe easier to the connecting element, it is desirable to moisten.

Option # 2: Compression

Widely used parts used for connecting pipes that can be called concentrated. Before installation, it is important to make sure that the sealing rings and the dielectric pads, which must be on the part shank.

To connect to the end of the pipe, a nut and a crimp ring is put on (if it has a cone form, then the process is carried out with a narrower side of the part). After that, the shank is inserted into the pipe (for this you need to make some effort), while in order to seal items, the part is covered with packles, flax, sealant.

The next step on the fitting body is put on and tightened by a cape nut. It is convenient to do this with the help of two keys: one of them is fixed the item, another nuts.

This method is sufficiently easy and does not require the use of special equipment, but it is undesirable to apply for hidden wiring, since it requires a connection check.

Option # 3: Push fittings

Comfortable connecting elements, for fastening which special tools are not needed. To install, it is enough to insert the product into the connecting part, while the end of the pipe should be visible in the viewing window.

Immediately at the end of the installation, thanks to the enabled water jet, the fitting wedge pushes forward, forming a clamp that prevents leakage.

This method allows you to quickly and easily create the necessary design, providing high-quality durable connections. Almost the only lack of push fittings is their high cost.

Option # 4: Press fittings

These items are used to create in-view connections using press ticks or similar devices.

To connect, you need to calibrate the item, removing the fez with it, after which the sleeve is put on it and the fitting is inserted. The sleeve is captured by the press clamp, after which the handle information is tightly clamped.

Such an element can be used only once, however mounted with fastenings are quite sealed and reliable, so that they are suitable for hidden wiring.

Installation of pipes from different types of materials

For the connection of the elements, one of which is made of metal, and the second - from the metal plastic, the special fittings are intended, one end of which is equipped with a thread, and the second is a socket.

For installation, the metal pipe must be chopped by carvings, clean the palauls, lubricate with soap or silicone, and then throw the fitting with your hand. After the second end is connected to the plastic element, the thread is tightened completely using the key.

Assortment of Fittings of Different Forms

For easy installation, the connecting elements may have a different form. Most often found:

adapters for connecting pipes with different diameters;
tees, providing branches from the central pipe;
corners to change the flow direction;
equipment (installation knee);
crosses, allowing to organize different flow directions for 4 pipes.

A special configuration (couplings, triangles, tees) may have press fittings.
