How to spend heating from polypropylene. Even newcomers will be cope! Making a heating system in a private house from polypropylene pipes with their own hands. Difference two-pipe layout

Old steel pipes in heating systems are constantly changing new ones. But steel is rarely put. Metals are increasingly displaced by products made of polymeric materials: polypropylene (also called PPR or PPR pipes) or metalplastic (MP). Moreover, MP gradually lies positions - polypropylene pipes won in price, no worse in characteristics, but at some positions are also better. The disadvantage can be considered the need to use special equipment for connecting pipelines (welding machine), but the seams have high strength (materials are fused, and a monolithic structure is created), the installation of polypropylene pipes is easy to make it yourself even without special skills. The inner diameter during welding does not decrease (in contrast to metal plastic). It is also necessary to say that you can learn how to use equipment for welding in several tens of minutes, so make a system of heating from polypropylene with your own hands quite real.

Scheme of heating

The scheme of the heating system from polypropylene, will not differ from the same, but from metal or metalplastic. The only difference is the diameters will be different. Until this parameter, no differences are not. Therefore, make a regular project without any features.

What is the difference between polypropylene pipes, it is a way of docking - they need to be welded using a special welding machine. . Another feature - because of the high elasticity, they are not bent. Therefore, in all places of turns and bypass, suitable fittings are used. About what are what happens.

Designation of polypropylene pipes for heating

Not all types of RPR products are suitable for laying heating, but only certain categories. The following types of polymers are suitable for heating:

Randa copolymer, which is indicated by PPR, PPRC PP-RANDOM. In the manufacture, polypropylene PR 80 is used more often, which has a low price and good characteristics: high chemical resistance, the uniformity of the material that leads to the ease of installation and reliability of the compounds.
Special heat-resistant modification, which is characterized by increased thermal resistance - up to 95 o. Products from this material are marked with PPS.
Stitched polypropylene, which is indicated - PP-XMOD or PP-X. With this material there are two Rehau and Valtek firms, famous for high quality products.

There are several more new brands: PP - RCT is a modification that has increased strength and PPR-100. They allow to produce pipes with smaller walls with equal other characteristics, but not yet used in mass production.

Polypropylene tubes are not normalized by gostami. There are standards for material. This is GOST 26996-86. According to this document, the conditional designation of the material consists of the name "copolymer" or "polymer", followed by a set of 5 digits. The first - 0 or 2 - denotes the pressure value at which the polymerization occurred (0 - the average, 2- high). The second digit indicates the type of material: 1-polymer, 2-copolymer. Three other - the amount of yield. Then the stabilization recipe cipher is adding through the dash. When painting, the name of the color and the forming code of the staining of three digits is added.

Sizes of polypropylene tubes

In general, polypropylene tubes are produced different sections and diameters. Sections can be square, oval and round, and radii (or sizes in cases with a square section) from 20mm to 600mm. For heating, only round-cross-section pipes are used, the diameter of which is in the range from 20mm to 40mm. These sizes are sufficient for the wiring of any individual heating system.

What is necessary to take into account when choosing, this is what the outer diameter is indicated during the labeling, and not internal. Internal calculated. To do this, the wall thickness takes place on the specified value. The wall thickness depends on the type of pipe and the type of reinforcement. The table includes the wall thickness values \u200b\u200bdepending on the diameter for the PPR tubes used in the heating PN20 and PN25.

What PPR pipes are used for heating

In the heating systems, reinforced polypropylene tubes are put. In principle, products from random copolymer or PPS, and without reinforcement will withstand the modes of most heating systems, but their linear expansion practically eliminates such an opportunity. The fact is that at the temperature of the transported medium above 60 o With each meter, the highway is lengthened by 6-7cm. This is noticeably visually: when the pipe is open, the pipes sag. With a hidden laying in the walls or semi, compensators or compensation loops are simply necessary in this case, a certain degree of freedom is also needed so that the pipes can change the dimensions. When deploying, this is a very difficult task. Therefore, in a hidden gasket, the narrated products are rarely used.

Manufacturers found a very worthy output and for heating with its pretty hard temperature mode: use reinforcement that creates a hard framework, which is why the extension when heating becomes less. It can reinforce them with fiberglass (expansion two times less) or aluminum (temperature expansion less than 4 times), and then they are indicated by Stabi PN-20 and Stabi PN-25. Such products are suitable for hot water supply and heating. The presence of the word "Therm" means high resistance to elevated temperatures. Such PPR tubes are recommended for heating.

Foil reinforcement is two options: with the location of the metallized layer in the middle and closer to the outer edge. Both options require a cut-off processing before connected, but this processing is different. When the central location of the foil requires ending with the use of a special tool for each pipe diameter. In this case, this tool is a carrier - removes foil to a depth of about 2mm.

When choosing, it is important to know the strength characteristics of pipes. For their designation in the marking, there are symbols that denote the nominal pressure. This is the magnitude of the pressure that this pipe is withstanding for 50 years at a temperature of the transported medium 20 ° C. For heating, PN20 and PN25 is used, which under the stated conditions are kept 20bar and 25bar, respectively. This does not mean that in the heating system, they will also serve 50 years old: with increasing temperatures, the service life is significantly reduced.

Installation of polypropylene pipes with their own hands

Two types of welding can be used to connect the PPR sections of pipes among themselves. Since the operating conditions in heating systems are rigid - elevated temperatures and pressure - usually a more reliable method of fuse-welding welding using fittings is used.

When assembling heating from polypropylene, you should mainly remember several key moments:

Now directly about how the welding process passes. Cooking the place to work, install the necessary nozzles on the soldering iron, include the network. Waiting until it goes to the working mode (control LEDs will be treated), start welding:

The pipe is cut off with a special pipe cutter with a sharp blade. Cutting direction is strictly perpendicular to the pipe itself. The slightest deviations can lead to a worsening of the quality of the seam. The cut itself should be smooth, without a burr (if necessary, smooth out small emery paper with small grain, but it is better to change the blade on the pipe cutter and make a smooth cut).
You can cut a tube with a special pipe cutter or aged hand-hacksaw for metal, but it is necessary to withstand the perpendicular cutting
If the pipe reinforced with aluminum is used, the cut-intoxial is cleaned or trimmed.
The pipe up to the stop is inserted into the fitting, on it 2 mm above the end of the fitting the marker is made a mark. Some firms have special planks, with which this label is set.
A pipe and fitting and fitting also put on the heated tip of the soldering iron and is very pressing toward the soldier. The effort is required decent. If you cannot insert both items at the same time, you first put the fitting - it has a large wall thickness.
Pipe pack better in gloves - there is a big probability of burn
Waving the right time, remove the details from the nozzles.
The pipes removed from the heaters quickly connect with the fitting with a sharp movement, pressing with an effort, withstand a certain amount of time (also in the table).
Turns or change of the position of welding elements one relative to the other is unacceptable. It significantly worsens the quality of the weld. If the docking turned out to be a curve, the plot is cut and the connection is attached to anew (it turns out more by one butt due to the pipe extension).
Leave before cooling.

Here on such a scheme and collect the entire pipeline. According to the experience of those who have already mounted their own pipeline, we can give advice: before starting the assembly, practice. Make several test seams. The plot of pipe will need for this small, and fittings for polypropylene pipes are a bit. Especially for training, buy some unnecessary pieces of the cheapest. The least cost clutches, but you can also purchase a corner, it falls differently in his hand, and the main work will be with corners, tees.

Hard places in the heating scheme from the PPR

If there should be no problems with the usual branching or a connection of two pipes of pipes, then in some specific places difficulties may occur. Often questions cause passes through the wall or roof and connecting the heating devices.

For the wire of the polypropylene tube through the wall or overlap, drill a larger diameter hole in the obstacle. Insert the sleeve or segment of another pipe into the hole. The length of the sleeve exactly corresponds to the width of the obstacles (less can not, it is more possible, but the appearance at the same time, to put it mildly, "not very"). The diameter of the sleeve by 5-10mm is greater than the outer diameter of the pipe paved. The resulting clearance is paved with a soft non-abrasive material, which does not limit the freedom of progress along the longitudinal axis. At the same time, the system is necessary to design so that the pipes in the passage of the pipe were whole without joints and fittings.

Now about connecting the heating radiator to polypropylene tubes. Pipe laying can be open and hidden. With a hidden laying from the wall, a pin or a small portion of the pipe can be out. To adjust the heat transfer level of radiators, thermal heads or special needle cranes are used. All these devices can be installed to sections and connect pipes then needed with them. If no additional devices are provided, the coupling with a cape nut is used. It can be combined with a corner (see Figure). To the output of these devices, the pipe is then welded, then it is then applied with the help of tees or corners with the corresponding pipeline.

One of the options for connecting the heating radiator to polypropylene tubes can be seen on the video. At the same time, look at how to solder pipes.

And on this video, the incorrect connection of radiators is disassembled. About how to do not need.

RESULTS

Heating from polypropylene can make anyone anyone. Even a person who does not have skills. Polypropylene welding is simple, it is possible to master it in half an hour-hour. Not at the level of professional, but in sufficient amount for the successful installation of the system. With a small and not very branched heating scheme, it is also possible to calculate the heat load and calculate the thermal load, as well as calculate the number of radiators and determine the diameters of the pipes. If this stage seems difficult, you can order a project and calculation in a specialized organization. And the installation of the heating system from polypropylene pipes will take from several hours to the pair of days depending on the scope of work.

Polypropylene tubes are popular due to the affordable price and quality of the material. Low thermal conductivity of the polymer retains the temperature of the coolant. Low equivalent of roughness of the inner walls of pipes does not reduce the flow rate. Simple assembly technology allows you to quickly mount heating in a private house from polypropylene pipes with your own hands.

Specifications of polypropylene pipes for heating

Abbreviation, with information about the working parameters of the product, is applied on the walls of the pipes. Basic marking of polypropylene (PP) complies with international standards:

manufacturer's logo;
lettering and addition to product modifications (PP-Random, PPRC, PPS);
conditional pressure (PN25 MPa) of the working environment;
outer diameter and size of the wall of the product;
operating class;
maximum allowable working pressure in bars, which indirectly indicates the service life of the product;
product standard.

A description of the design features, appointments and areas of application of the product leads a manufacturer in a technical passport of the product. Table, as an example, provides data on the products of the manufacturer Valtec (Italy):

Class	Place of application	Working pressure, bar

Products with internal insert Aluminum foil are used mainly for heating. The reinforcement of polypropylene tubes with fiberglass also allows them to use them in radiator circuits, warm floors and hot water supply of private houses. However, the pipes with the inner layer of fiberglass fibers admit a slight lengthening of linear sections when heated and the permeability of oxygen.

Fittings and valves for heating systems from polypropylene are performed from a similar material of the Random pipes of the copolymer. Elements without thread are designed to connect to a slur, in which the pipe is inserted into the fitting case. The inner diameter of the connecting parts (corners 90? And 45?, Couplings, adapters, tees, crosses and cranes) corresponds to the outer diameter of the pipe. Linear temperature expansion leveled ready-made compensatory loops or welded designs of self-performance.

Clamps (single and clips blocks) are designed for fastening direct, horizontal or vertical pipelines along the walls. The fastener installation step (recommends the manufacturer) depends on the size of the pipe and the qualitative parameters of the coolant. Clauses from similar raw materials are designed to attach PP pipes of large diameter. Fastening can be rigid or floating, a small gap will provide the possibility of free stroke with thermal expansion.

Connection with steel pipes or reinforcement is obtained using combined connecting parts. Collapsible fittings (American) for transition from metal on the polymer are released with internal or external carvings from galvanized metal on one side, and propylene insertion on the other.

A set of shaped and connecting parts is selected individually for each room in the house. The number and brand of fittings depend on the configuration of the heating system and the type of heating equipment.

Price propylene pipes for heating

The cost of the product depends on the destination and manufacturer. Famous domestic manufacturers specializing in the production of reinforced PP pipes: "Synikon" and "Yarintersplast".

PP tube PN25 MPa pipes are used for heating. The price of polypropylene reinforced fiberglass pipes is below the products with an internal aluminum frame (approximately 10%). The difference explains the guaranteed service life of the product, the resolved temperature of the coolant and the system operating pressure.

The average cost of polypropylene pipes for heating (price per meter):

Pipe diameter, mm	Producing country	Operating class / type of reinforcement	Price, rub / PGM
25	Italy	5 / Aluminum	33,75
32	Italy		47,25
40	Italy		79,50

According to the reviews of professionals, polypropylene pipes for heating are the optimal version of autonomous systems. A homogeneous soldering structure without threaded compounds and metal fittings is easy to install and convenient during operation.

Polypropylene pipes in the water heating scheme of a private house

The pipe layout transmits the flow of thermal energy from the boiler to the heating devices. Water is the traditional heat carrier of heating systems for country houses. The amorphy of the polymer to the aggressive medium under the action of high temperatures is the key to the durability of pipes. The inner surface of the pipes has an insignificant resistance to the directional movement of the flow. The impurities contained in the coolant in a suspended state (organic, compounds of stiffness salts, scale, sand particles), do not form deposits on the walls of pipes from polypropylene. The products reinforced by aluminum eliminate the access of oxygen into the heating system from the pipeline. The foil metal layer reduces the risk of corrosion of the heat exchanger of the boiler, increases the resource of the system as a whole. Numerous materials, diagrams, video heating with their own hands in a private house can be easily found on the Internet.

Pipe layout emergency freezing does not threaten the destruction of polypropylene pipes. After the water defrost, the material restores the initial properties. However, it should be remembered that it is impossible to warm up the pipes from PP with an open fire!

An increase in the linear dimensions of the pipe with heating is perhaps the only significant disadvantage of polypropylene products. The reinforcement of the aluminum foil reduces the temperature expansion at times and increases the level of pipe classity.

Considering that the optimal pressure in the loaf of the household boiler is 1.5? 2 babe, the heat source is as close as possible to the consumer and the temperature in a residential building does not fall below 5 ° C, we conclude: aluminum-reinforced polypropylene - perfect pipe wiring material in a private house.

Contact thermal welding

Installation of systems of heating from polypropylene is produced at a room indoors not lower than 5 ° C. The consumables for heat sewer (components) must match the assignment (PPRS).

Sequence of operations in the manufacture of nodes at the workplace:

cut pipes produce special scissors on pre-marking on the case;
preparation of the cutting surface includes chamfering to a depth of 1 mm at an angle of 30 ° and degreasing the end of the pipe with acetone;
melting boundaries mark - to the end of a pipe, a pencil is applied by restrictive risk;
processing of the work surfaces of the soldering iron;
tool heating;
melting parts (with an exposure of time ranges of pipe diameter through the passport of the device, and the coaxiality of parts with an iron housing);
docking knot without displacements and rotation of elements;
cooling.

Electrotock voltage in a soldering iron for polypropylene - 36B. The operation of the tool from the household network requires the presence of a shutdown safety machine.

After cooling the compounds, the rectinity of the joint, the uniform of the weld roller and the absence of welding defects is checked. The number of connecting nodes, when performing the rules of contact welding, does not affect the bandwidth of the system. Small resistance in welded parts is due to the physical properties of the material and the connection method without reducing the pipe cross section. Hydraulic tests for strength and density of the PP pipes are carried out 16 hours after welding.

Water heating schemes from polypropylene for a private house

Non-volatile or pressure, single or two-pipe scheme is chosen based on considerations of efficiency and comfort. Traditionally, private homes are equipped with horizontal wiring with independent floor circuits. The system of heating small houses with natural circulation represents a chain of a sequential connection of radiators. Effective heat supply of the house of a large area is carried out by two-pipe wiring with the coercive movement of the coolant.

High-quality installation and equipment is impossible without calculating the bandwidth and determining the diameter of the pipes on each site. The coincidence of the calculated and actual expenses will reduce heat losses, ensure a stable, reliable and silent operation of the system.

With the help of an online calculator, you can make a hydraulic calculation for a single-pipe scheme of water heating of a private house with your own hands. DANFOSSCO and OVERTOPCO programs produce calculations of intrama heating systems with natural circulation. Calculations in Excel Online are reduced to a convenient tabular form. By completing the source data Count and selecting the necessary constants (columns are highlighted in color), we obtain the calculation results.

The classic method of arrangement of the heating system is a single-pipe layout. Claim the installation will be able to themed video of the private house of propylene. With your own hands, you can quickly, carefully and cheaply fulfill the strapping of equipment.

Systems with single-tube wiring and natural circulation are operating under the action of the forces of gravity. The slope when laying pipes and the installation of the heat generator below the level of residential premises will increase the flow rate of the flow. However, with a sequential connection of radiators, it is impossible to evenly distribute heat. The premises deleted from the boiler warm up badly, the danger of cessation of circulation and boiling the boiler water occurs.

The problem solves the device for heating a private house with their own hands in the Leningradka scheme. Video clips can be found on the net.

The removal of the nozzles to the heating devices is separated by the stream, most of the coolant continues through the system on the system. Consumption through the radiator is controlled by setting the thermostat valve, diagonal connection of the device or by changing the passage cross section of the bypass.

The main components of heating are heat generator, pipes and heating devices. The rest of the equipment ensures the performance of the system at various loads. Equipment of the system with additional elements depends on the size of the house and modify the selected boiler. The specified parameters of the unit provides a security group, an expansion capacity with a overflow tube, a supercharger and a pressure adjustment device.

If the circulation pump is not embedded in a boiler circuit, the supercharger is installed on the reverse line of the pipeline, in the immediate vicinity of the heat generator. Place the installation of an expansion tank of a closed type for heating - in front of the circulation pump. The security group is mounted on the feed line near the boiler.

Comfort concept individually for each person. But for everyone, without exception, the house is warm. Heating is an integral part of any house. Take a competent solution and embody it on its own forces will help maximum awareness in this topic.

Content

The popularity of polypropylene pipes is explained by the technical characteristics and properties of the material, as well as the available cost. Due to the small roughness of the inner surface, the rate of coolant circulation does not slow down, and the low thermal conductivity level retains its temperature unchanged. The ease of connecting elements allows you to collect heating in a private house from polypropylene pipes with your own hands in the shortest possible time, minimizing costs.

We make heating from polypropylene on their own

Specifications and features of polypropylene pipes for heating

The main technical parameters of pipe elements from polypropylene material can be found from marking, the symbols of which are an abbreviation.

As a rule, the designation is applied to the outer wall of the product and contains:

recognized at the international level of polypropylene - RR;
manufacturer's name;
a literary cipher denoting material modification (PP-Random, PPRC, PPS);
maximum pressure of the movable medium, in MPa (PN16-25) and in bars (1.6-2.5);
operating class;
diameter and wall thickness;
standard manufacturing.

Marking of the PPR tube

The physical properties of polypropylene heating pipes indicate indisputable advantages over metal products. This can be attributed:

high thermal insulation characteristics;
plasticity, due to which the material carries several frost cycles and subsequent defrosting;
resistance to the effects of aggressive substances;
immunity to corrosion processes;
easy to dock the elements.

When assembling the heating system by polypropylene tubes, spike individual segments are performed. The advantage of this method is to minimize the number of threaded, fitting and other assembly connections. Spike eliminates the likelihood of leaks, therefore the hidden laying of the line is allowed.

The cost of polypropylene pipes is comparable to the price of rolling from ferrous metal, but significantly lower copper or steel products.

A feature of PP pipes is the presence of important restrictions on installation. Not allowed:

performing strapping when connecting to the boiler;
use in solid fuel boilers in smoke systems;
application as a pipe for gas supply.

When buying, you need to pay attention to the temperature parameters of products. They must meet the values \u200b\u200badopted on the project for heating systems from polypropylene pipes in private houses.

Rules for choosing pipes for mounting the heating system

Select size

The diameter of the elements is selected depending on the heating scheme in a private house.

When creating a sampling system (without pumping a pump), the pipe cross section should be selected with a large diameter, since the absence of water injection must be compensated by an increased coolant.

Transition from metal to propylene

Installation of the heating system from polypropylene pipes is not possible without connecting them with metal-plastic or metal products. At the same time, the regulatory combination of sections of the connecting pipes from various materials should be taken into account.

The length of the contour for which the device for heating from the boiler with a capacity of up to 12 kW is effective, is about 25 m. For heating of six decide radiators, a PP pipe 20 × 3.4 mm will be required. If it is necessary to lengthen the highway, it is necessary to make heating from elements 32 × 5.4 mm or a radiation wiring.

Options wiring

PP-pipe wiring is performed by two main ways:

horizontally;
vertically.

Mounting in accordance with the first option is possible when arranged in the house of the central riser, from which one or two-pipe horizontal branches are deployed to each flood. Choose this kind of system for heating two or three-storey buildings of both residential and commercial purposes, as well as in the past few years - and for apartment buildings.

The horizontal layout option can be divided into two types:

ray;
perimetral, in which the heating system is removed from the central riser.

The coolant for each floor or inside the apartment circulates in stages, which creates considerable inconveniences for tenants. If necessary, repair work or replacement of a separate heating radiator has to completely disable the entire perimeter.

The advantages of the heating system from the polypropylene of the perimetral type are that the pipeline is possible to be laid in a hidden way, under the floor. All wiring is placed in one horizontal level, without occupying an excess place. But the drainage of the coolant from the separate perimeter is difficult.

Choose fittings

When the heating device from polypropylene pipes, with their own hands, one of the weakest places requiring more than the cost of time is the adhesive connection of individual nodes and sections. Instead of welding, fittings that have different shape and section can be used.

Varieties of fittings

Mounting pipes most often requires the use of the following types of fittings:

adapters;
tees;
couplings;
compensating inserts;
corners.

The coupling is the simplest type of connecting devices, which is used when connecting the pipes of the same diameter. Adapters are used to dock the pipes of different sections.

Corners will be required in places of rotation of the pipeline. They allow you to arrange the maintenance of the pipe in the desired side at any angle without deformation. Elements have an outer metal thread, which allows you to perform a joint assembly of the PP pipe with any plumbing devices and devices.

Triple fitting will help connect several pipes at the same time. Such parts are performed from plastic and are suitable for pipelines, characterized in both diameter and manufacturing material.

For pipeline lines going around the object, special fittings are manufactured - Opports. With their help prevents excessive bending of pipes.

Using all these elements, you can dock the pipes using a rifle connection. In such cases, the use of "American" is necessary. Such a fitting has, on the one hand, a metal thread, and on the other - the base of polypropylene. Thus, a reliable compound of metal and plastic is ensured.

When choosing fittings, it is necessary to pay attention to their cross section. It must correspond to the diameter of the pipes.

It is recommended to buy fittings that exactly the manufacturer, from the pipe products of which it is planned to assemble the heating system. Only in this case can we talk about the quality of the connection.

We make a heating scheme

Scheme of housing heating using polypropylene pipes is no different from the schemes using other materials. She may be:

single or two-pipe;
collector.

One-tube connection diagram

One-tube is used for short-length contours in small square homes. The only pipe alternately connects all the instruments and comes to the heating device through the return. The circulating fluid loses part of the thermal energy, because even when installing regulators, it is not possible to achieve uniform heating of all rooms.

Heating in an apartment or a private house with two pipes provides for the purpose of one separate line for supplying the coolant and for the return. The productivity of this option is somewhat higher than the previous one, but it does not solve the question with the uniformity of heating radiators.

Two-pipe connections

The best option for private houses of a significant area can be called the heating system arranged on the collector (radiable) scheme. From the distribution manifold, pipes (feed and reverse) depart to separate heating devices and small contours. At the same time, hot water is fed to all sections at the same time.

The collector scheme is arranged with the upper or lower wiring. The first option provides for the location of the highway in the attic room, risers are descended to individual circuits or devices. At the top point for air diversion, a special valve is installed. This method of heating a private house is used with their own hands with the natural circulation of the coolant in buildings height from two floors.

Collector connection scheme

The lower installation involves the installation of the highway below the floor level, the risers in this case go up.

Step by step guide

The installation of heating from polypropylene begin with pipes inside the premises for their "acclimatization" and eliminating the effects of expansion or narrowing at the heat or with a strong frost.

The main work when connecting pipes is polypropylene welding (spike). For these purposes it follows. The process itself does not take much time and is easy. The main thing is to quickly connect the heated ends of the elements, trying not to overlay them. The duration of heating depends on the diameter of the pipe. What it is more, the longer the heating should be. The secession of the soldering device should fit the pipe diameter.

Technology soldering pipes

Step-by-step instructions for assembling the heating pipeline looks like this:

a wiring scheme is drawn up;
on the walls for all sites, markup is performed, focusing on which elements of the heating system will be laid;
fittings are selected;
the time is determined for the installation and execution of welding;
pipes are scheduled and cut into segments of a certain length, the cut is performed at a right angle to the axis;
for degreasing and removal of dust microparticles, the ends are cleaned with alcohol, dust is removed with a dry clean cloth;
soldering nozzle is degreased, it is installed in the working position and is heated to +265 ° C;
a fitting and pipe fittings are placed in the nozzle, their joint heating and docked with each other are made;
waving the time required for cooling, the connected portion is attached to the wall through clips.

The heating from the polypropylene does with their own hands also requires the installation of control equipment, boiler, heating devices, an expansion tank, pump. Mounting them is carried out according to instructions and manufacturer's recommendations.

Nuances Mounting Polypropylene Pipes

How to correctly perform the installation of the heating system from polypropylene in a private house?

In the immediate vicinity of the boiler, all reinforcement and pipes are installed only from metal. Crane from plastic can not be installed, as it will come into disrepair too quickly and will flow. It is recommended to place a bronze crane and a threaded adapter, and for them - pipeline from polypropylene.

Connecting to a pipeline boiler should be made through an "American" connection. The plastic cranes near the taps-tees is not recommended, as this makes it vulnerable to the entire knot: when the crane exits, the crane is due to the replacement and crane, and fitting.

Compound "American"

Before you do the home heating, you should draw up a plan at home, showing it every element. All elements of the system should be provided for unhindered access in case of possible repair, replacement or shutdown.

In horizontal sites, the installation of a mud filter is required, and on both sides - cutting the cranes that exclude the need to drain the water from the contour.

There should be a distance of at least 5 cm. Pipes are fixed on a wall with a fastening step depending on the diameter and the type of product.

If you yourself collect the heating system from polypropylene, you should consider the most important feature of PP products: the ability of the material to increase the length to 15%. When heated, the length of the contour may increase, which will lead to its deformation. Therefore, for each site, more than five meters is required to install a compensator. It is made in the form of the letter "P" from the taps or use the finished loop.

Due to the thermal expansion, most supports must be made movable. When installing a P-shaped compensator on both sides, an attachment is required using movable supports.

Compensators need to install the loop down to avoid importing system.

Installation of the heating system from polypropylene pipes can even fulfill a person who has no experience. The process is simple enough, it does not take much time, and with a proposed project and following the work of work, ensures efficient and reliable home heating.

To increase the efficiency and increase the operational period of the heating system, professionals are recommended to carry out the installation of heating in a private house with their own hands using polypropylene pipes. After the expiration of the year, the efficiency of their analogues of metal decreases, all because at elevated temperatures, these pipes begin to rust from the inside.

The advantages of the system of heating from polypropylene

For this heating scheme, the mass of advantages is characterized, among which it is worth highlighting the following:

Disadvantages of polypropylene products

It is very important to buy only in proven manufacturers, since their disadvantages are directly dependent on the use of low-quality raw materials, as well as violations of production technology.

For heating, types and installation with your own hands

Currently, the construction market offers a huge selection of polypropylene products. However, before you purchase them, you need to deal with their properties and labels.

PN-10 pipes

These products have an outer diameter of 20-110 mm, internal - 16.2-90 mm. For the manufacture of such pipes, a thin-walled polypropylene is used (thickness of 1.9-10 mm), which is designed for a temperature in the system to 20 ° C and the working pressure is not higher than 1 MPa, so it is not used in heating systems.

PN-16 Pipes

Their use is allowed at temperatures up to 80 ° C, but this type of pipes occurs very rarely, in connection with this they are almost not used.

PN-20 pipes

These products have an inner diameter - 10.6-73.2 mm, an external - 16-110 mm, the wall thickness may be 1.6-18.4 mm. These pipes are calculated at temperatures up to 80 ° C and the operating pressure is not higher than 2 MPa. This is universal. However, in the heating system, they can be used exclusively in the return pipe, and the water temperature should not be higher than that indicated earlier.

PN-25 pipes

This is the most optimal option in order to make the installation of heating in a private house with your own hands. The main distinguishing feature of these products is their multi-layer execution (two plastic layers, between
which layer aluminum treated with glue). The aluminum product has an outer diameter, equal to 21.2-77.9 mm, and internal - 13.5-50 mm. Such polypropylene functions in the heating system with a working pressure not higher than 2.5 MPa and temperature up to 90 ° C.

The presence of an aluminum layer reduces the expansion coefficient of pipelines during the passage of the coolant. However, when choosing reinforced products, it is necessary to take into account its location. If the layer is placed closer to the outside, it will make it difficult for the spike process, in this case, the installation of heating in a private house with your own hands in this case will require the acquisition of additional equipment (special carrier or boiler).

Another kind of type is reinforced with fiberglass pipelines, they are similar in quality indicators with products with foil layers. However, for the first type, a high thermal expansion indicator is characterized, but their installation is slightly simpler.

Connection of pipes

For (diameter up to 63 mm) two main technologies are used:

Pour spike - one end of the coupling is introduced into another, extended specifically for this.
Coupling welding - in a special detail (coupling) includes both ends.

A threaded connection can also be used, the fittings applied to its execution are applied.

To connect pipelines (diameter of more than 63 mm), the technology of welding is applied. In this case, the clutch installation is not required, since this compound has high reliability. If there are suitable fittings, you can use welding couplings.

Design of heating systems

Before your hands, it is necessary to correctly proceed.

If the installation of heating is carried out in a rustic house, the boiler should be installed in a separate room. The apartment allows its placement in the kitchen or in the hallway. The room must be equipped with an exhaust system.

When planning the heating system, it is important to consider that the return pipe should not be lower than the feed in the boiler, otherwise the circulation will be somewhat difficult or not completely impossible. To do this, make a three-dimensional pipeline scheme with an indication of heating devices, levels of passing enclosing structures and corners of turns.

It is worth noting that heating from polypropylene pipes with their own hands in a private house is much easier than any other system. According to plan, the length of the pipeline, the number of connective and rotary parts is calculated.

Types of mountage

Installation of a system from polypropylene products can be carried out in two types:

The upper spill is a self-type type, which is caused by the temperature difference. Such a system in private homes is the most common, as it is simple, reliable and does not require the installation of expensive pumping equipment.
The lower spill is the movement of the coolant for the heating circuit is carried out forcibly by means of a pump. The main advantage of such a system is the possibility of its use in multi-storey buildings. In addition, it is possible to use small diameter pipelines, with such a wiring configuration it does not matter.

Tools and equipment required for installation

To carry out the heating of a private house with their own hands (the system scheme must be drawn up in advance), the following will be required:

Polypropylene pipes with different diameters (for eyeliner to heating devices and the main circuit).
Scissors for polypropylene.
Electric equipment with set of nozzles.
Perfederator may be required for the walls of the walls.
Marker.
Roulette.
Wall mounts (plastic clips or metal brackets).
Couplings, corners, adapters.

Heating in a private house do it yourself: schemes, calculation and installation

The main moment when installing the system from polypropylene pipes, on which it is necessary to concentrate special attention is the compounds of structural elements (pipes, fittings). For this, a special welding machine should be applied.

To install the heating system from polypropylene, it is necessary:

First, it is necessary to draw a pipeline location scheme.
Then the metrar of polypropylene pipes is calculated. The calculation is carried out according to the scheme specified in the previous paragraph.
The length of the pipelines on each individual area is calculated.
Fittings for the desired size are selected.
Further, before installing the heating of a private house with your own hands (the scheme should be drawn up in advance), you need to purchase all the material and give it about a day to lie down at room temperature. This is required in order to in the process of installation and subsequent operation on the plastic, cracks appeared as a result of sharp temperature differences.
In the pipelines, the stamps are performed.
On the scheduled marker lines, sections are made by means of special scissors.
The solder apparatus is placed on the horizontal surface, an low-fat nozzle is set equal to the diameter of the pipeline.
The soldering tool is heated to 260 ° C.
Fittings and pipes are placed in the hole of the heating element. After that, their heating is carried out.
Details are extracted, and the pipe is inserted into the fitting. It is important that the specified details in the compound process are not cold.

When the water heating is in a private house, the scheme and installation with your own hands are fully fulfilled, before the full start of the system, it is necessary to pre-test it. Pipelines for some time (at least two hours) are filled with water to detect troubleshooting and timely elimination.

Montaja rules

Each person, performing the heating of a private wooden country house with their own hands, should adhere to the following rules:

To know how to properly install the heating of a private house with your own hands from A to Z, it is advisable to get acquainted with the following recommendations:

Polyethylene pipelines are allowed only if the air temperature is at least +5 ° C. Otherwise, it will be absolutely impossible to achieve the perfect compound, and as a result, the heating system will fail too quickly.
Before making a soldering, it is necessary to remove all the dirt from the edges of the pipe. This can be done with a dry clean vet. After that, the surface is cleaned with alcohol, which is divorced with water in proportion 1: 1.
The time of welding and cooling pipelines is determined by a special directory, depending on the diameter of the purchased products.

Conclusion

The heating system from polypropylene pipelines today received its fairly widespread among consumers due to its advantages, low cost, reliability and simplicity. Now and you know how to install the heating system with your own hands - from polypropylene products. This article helped you make sure that the installation of this heating system, including welding pipes, can be independently without avoiding assistance. And most importantly, the use of such a system is possible not only in one-story building, but also in apartment buildings.

Compound of polypropylene pipes

Heating with polypropylene pipes with their own hands can be installed under the condition of the ability to weld polypropylene tubes. As a last resort, the minimum requirement in order to mount the polypropylene heating is "a huge" desire to learn how to weld such pipes and fittings.

Types of welding:

coupling (flarified) welding - used when welding two pipes with a diameter of up to 63 mm using a third element - couplings;
butt - used for welding pipes of a large diameter "Online" and involves the use of special centering equipment

Coupling welding of polypropylene parts

Polypropylene heating is usually mounted by manual apparatus for welding polypropylene pipes, which has special nozzles: sleeves and Dorn.

The sleeve is designed to warm up and melting the outer surface of the end of the pipe, and Dorn is used for heating and melting the internal termination of the connecting element (coupling).

The diameters of such nozzles should correspond to the diameters of the coiled pipes, and their surface has a teflon coating that provides an anti-receptacle effect.

Attention! In the process of performing work on the installation of heating systems from polypropylene pipes, it is necessary to monitor the purity of the surfaces of the heating nozzles, and, as they need to be purified by wooden chopsticks from the adhered polypropylene fragments.

Important! Clean the surface of the nozzles can only be preheated!

To work on the welding machine, the necessary nozzles are installed, and it is placed on a flat surface for the "stationary" welding.

If it is necessary to perform work "on the wall", the nozzles are fixed on the edge of the heating element of the soldering iron.

For polypropylene pipes, the optimal welding temperature is 260 o C. Before starting the work, the device must be warm up within 10-15 minutes.

Attention! Contraindicated with welding of polypropylene pipes at ambient temperature below 0 o C.

Popular welding of parts with each other is performed in such a sequence:

Truboresis or with scissors cut a pipe at right angles.

If the end of the pipe or fitting is contaminated, we clean them, degrease the soapy water or alcohol and dried.

If PN 10 or PN 20 pipes are welded, then we skip this step, immediately passing to the 4th.

For welding reinforced PN 25 pipes, a pre-special tool is a special tool to remove the two upper layers: polypropylene and aluminum. The depth of stripping is determined by the depth of the planting place of the crop. Often it corresponds to the depth of the tube processing with a shader.

We put the welded parts on the heating elements. Heating of the parts connected occurs simultaneously.

After heating, we remove them from the nozzles and quickly connect, without turning along the axis.

Withstand some time for pouring and cooling the polymer. Or, what a deformation of the connection site during the cooling period is unacceptable.

Attention! If an unsuccessful connection is obtained, there is only one way to fix it - cutting the fitting and the welding of the new one.

Pay attention to the correct positioning when welding ball valves - they have a rotary handle, which in no case should "persist" into the wall or other adjacent object.

We check the appearance of the welded joint, which must comply with such requirements:

there is no significant violation of the coaxiality of pipes;
the clutch surface (couplings) should not have cracks or other defects;
near the clutch edge parts welded to the pipe should be visible to a solid band located along the entire roller circumference of the melted material, which should be over the end surface of the connecting part.

Shock welding

Butter welding is performed using special equipment and is used for polypropylene pipes with a wall thickness of more than 4 mm and a diameter of 50 mm and more. In detail in the context of this article, we will not consider this issue.

Welding polypropylene pipes and your health

When welding with polypropylene tubes for greater safety of your health, you must perform a number of such rules:

work carried out in a ventilated room;
remember that the welding tool is a power tool that integrates safety when working with it;
to avoid contact with open fire polypropylene, which can cause the formation of a melt with the release of carbon dioxide, water and other gaseous products is far from useful for their inhalation.

Swading the saddles to the finished pipeline of the heating system

If, after performing installation work or during the repair of an existing heating system, it was necessary to create any additional branch from the pipeline, you can use the welding method of the saddle. This method is also used to attach a smaller diameter pipeline without special adapters to the larger diameter pipeline.

Distinguish a welded saddle and a welded saddle.

Installation of the welded saddle involves the use of a special drill cutter for the preparation of landing space

The process of boiling or welding the saddle:

Preparation of welded surfaces - clean, low-fat, dry.
For a welded seat with a cutter is preparing a landing place. In the case of installation of the fitting to the reinforced aluminum polypropylene tube, a milling foil layer is needed to ensure a larger contact area of \u200b\u200bthe surfaces of the surfaces.
Heat the welding machine to a temperature of 260 o C.

The process of proper welding of such elements involves the use of special semicircular heating sleeves on the welding machine.

Their absence can create additional difficulties when installing, but at a certain skill, you can warm up the coiled surfaces and the usual nozzles of a suitable diameter, although ... Who will guarantee the quality of the connection?

The heating of the pipe surface continues approximately 25-30 s. At the same time, the surface of the welded (welded) seat is heated at the same time (about 20 s).
Recalling the welding tool quickly with one movement to press the saddle to the heated section of the pipe and secure the connection to 30 s. After 7-10 minutes, this saddle is suitable for further "mounting operation".
In the case of the use of a welded saddle after its installation, it is necessary to drill a hole in the pipe of the planting place with a spiral drill of a suitable diameter. At the same time, it is necessary to avoid chips from entering the pipe, as well as control the depth of the drilling in order not to damage the opposite wall of the pipe.

Features of the installation of polymer pipelines

When heating from polypropylene pipes is mounted, it is necessary to take into account the temperature expansion of such a material along the longitudinal axis.

The maintenance of the pipeline is usually performed at ambient temperature in 15-30 o C, and the temperature of the coolant in these pipes during operation of the heating system can reach sufficiently high values \u200b\u200b(up to 95 ° C - 110 ° C in closed-type heating systems).

And this means that unarmed polypropylene tubes can change their size by 10-12 mm for each pipe memory meter. For reinforced polypropylene pipes, this value is 2.4-2.6 mm. With a significant total length of the pipe of the heating system, its expansion (lengthening-narrowing) will be substantial (for a five-meter pipeline more plus 60 mm).

Therefore, when installing extended highways of heating systems, it is necessary to use pipes reinforced by aluminum foil. In the systems of warm floors, use and unarmed pipes are allowed in the case of laying them into a concrete screed, but preference is given to the reinforced options.

Attention! If you do not want the pipes of the walls of the walls and plates of overlapping when installing the heating by polypropylene pipes, they must be placed in "clothes" from polyurethane foam "housing", which will play a double role: and thermal insulator, and shock absorbing material.

The fastening of polyurethane pipelines is performed using mobile and fixed fasteners.

To compensate for linear expansion or reduction of pipes in heating systems, various techniques are used: fastening the pipeline on rigid (fixed) and moving supports, as well as the creation of compensatory areas (compensators) of the pipeline.

Hard supports suggest a fixed fastening of the pipe in them. This allows you to divide the entire heating system to certain compensation sections, in each of which the compensatory "mechanism" must be provided.

Movable supports play a supporting role and allow the pipes to move in them with its temperature linear deformation. When taking the pipes from the riser, it is very important to take into account its temperature expansion due to its significant total length. For this purpose, the "free removal" technique is applied.

The heating circuit from polypropylene should also "take into account" the possibility of elastic bending of the pipeline with linear extension of the riser. Laying pipes in the channels and mines involves the installation of hard attachment points at a distance of up to 3 m. And for temperature expansion, rather its compensation, use linear elongation compensators. Usually these are M-shaped or P-shaped compensation elements.

The heating circuit from polypropylene pipes implies "automatic" creation of P-shaped and M-shaped compensators when around bypass pipeline walls, corners, columns and other construction elements.

Attention! In long trunk lines, it is necessary to schedule the installation of compensation elements.

This compensatory installation option is "snake", mainly used for rolled in the bay of metal-plastic pipes. Usually from mounted in closed niches and at the same time they do not straighten completely. Loss of aesthetic species (still closed from human view) allows you to create natural compensators of linear elongations.

Laying! The system of heating from polypropylene pipes is an elastic system, providing for its correct fixing, fastening into a fixed support.

When the heating from polypropylene "hides" in the walls you need:

leave in the wall under the stucco on vertically and horizontally located areas with tees and knee leave free space in 3-5 cm;
to compensate for the linear expansion of pipes in the axial direction, it is necessary to provide a distance from the rotation of the pipe to the obstacle at least 10 mm per meter of the length of this straight line of the pipe;
when installing pipes in the strokes, their size should at least 70-80% exceed the size of the pipe diameter, and its very can be put into tubular insulation (foamed polyethylene or polyurethane):
with this installation, the "centering" supports can be created from the mounting foam, placing and fixing the pipe uniformly in the center of the shock;
the strobe is not attached, but is closed by a plaque;
also possible laying such pipes in the sleeve from the corrugation.

Based on the foregoing again, repeat: for laying pipelines of hot water supply and heating, it is better to use reinforced pipes with all types of laying - open or closed in an embossed niche or under the plaster. It is much easier to apply the reinforced pipe than to use cheaper unarmed and invent a lot of tricks for the possibility of its temperature elongation.

When passing the pipeline through building structures, it is necessary to use plastic or metal sleeves with a diameter of 5-10 mm large diameter of the pipe. The clearance is filled with a soft elastic material that excludes the penetration of moisture and sounds through the sleeve and the "resolution" longitudinal "temperature" movement of the pipe relative to the sleeve.
