When repairing the pipeline, the main requirement is the tightness of the compounds. The functionality and trouble-free operation of plumbing, heating, gas and other systems depends on them. What is the tightness achieved?

Most often, when installing and repairing the water supply, a threaded connection is used - it is inexpensive, quickly and practical. Having at hand just wrench, Plumbing can easily disassemble and assemble the system, replacing the node failed. But the thread does not give warranty that the connection will be perfect, another sealing component is needed.

What seals offer building materials market

There are several types of sealing materials that differ in the cost, convenience and reliability of use:

• Tape FUM (fluoroplastic sealing material)
• Sealing thread
• Linen thread

Among all offers fum ribbon is quite a caprication in use, the sealing thread has good qualitiesBut too expensive, and only Len is an impeccable tool proven for many decades.

How to wind flax on the thread?

So that the connection was durable and hermetic, threaded areas must be cleared of rust with fine-grained emery paper. At this stage, it is important not to damage the thread. Then it should be checked if there is no wins on the thread - with them the flax threads are fixed and the parts are not shifted when the parts is connected. If there are no notches, they can be applied with a file or plumbing key.

The correct winding of flax consists of several steps:

• Check the connection density with clean, threadless, to understand what thickness winding should be performed.
• Take the flax bundle and separate the strand of sufficient thickness from it to obtain a dense connection. Flax hairs should be one length, without lumps, straw and garbage.
• Milit from strands a loose harness so thick so that he can fill out one thread groove.
• Holding the end of the linen harness at the edge of the thread, to wind it in the direction opposite to the spinning of the nut. Each subsequent turn must go to the previous one. It is important not to overdo it with the number of layers, there must be no more than two, otherwise the connection can burst when twisting or from hot water When operating. If the harness turned out to be short, the winding should be continued by the next beam.
• Inspect reverse side Winding and make sure the absence of Lysin.
• On top of flax to apply a layer special pasta or silicone and twist the connection until the pasta hardened. The use of the sealing composition contributes to the durability of the compound, prevents flax rotting, helps to easily disassemble the design in the future. You should not use a sealant as a seal, such a connection is difficult to disassemble.

In order to combine two plumbing parts and get a good hermetic compound that will not give the leakage, you can use different ribbons or wind the places of compounds with the help of traditional flax. Mostly compound sealing flax, because it is much cheaper, and the connection is more reliable.

In cases where to compact with flax, I do not work, using a plumbing tape, also in the process of work I use sealing pastes of unipacled and multipact.

The sealing paste is necessary in order that in the pipes of hot water and heating systems, Leng did not roar and did not spoil from exposure to high temperatures, otherwise the compound may lose hermetically.

Previously, for these purposes, Len was deceived by paint, now a more convenient sealing paste came to replace it. If necessary, disassemble the compound treated with paint, it becomes impossible in a year if it is not necessary to process flax, the connection will quickly give a leak.

When using sealing paste, you can adjust the connection.

Flax is sold in different packaging and packaging, it can be purchased as sinks and separate threads, so if necessary, you can use the finished span and invent anything. Again, this is not the most cheap optionMoreover, quality with this option leaves much to be desired.

Poor-quality flax is different in that it is rough, has pretty nasty smellAnd from it will not be able to make a strand of the desired thickness.

How to properly blow up the thread?

In this matter, the most important thing is not to overdo it - if you have too much flax, the resulting connection can burst, if you have too little flax, then it can flow. Must be observed golden middleAll this comes along with practical experience.

How to use the sealing paste - how to use Unipak (Unipak)?

Manufacturers recommend spreading the paste to the pre-cleaned thread, then turning on top of the flax, scrubbles on top of another layer of unipaca. It can be done and easier without prejudice to the quality of the connection. For example, either to smear Len only from above, or to dip the whole strand into the sealing paste - the effect will be the same.

Screw the flax on the threaded connection is necessary in the direction of movement of the clockwise in such a way that it is not unwound when spinning parts. After Len was wound, and the sealing paste was namazan, the connection must be conscientiously pulling together with two keys and move to the next stage of work.

How to wind threads?

To seal the compounds, you can use the choice of flax and plumbing paste. In this case, it must be borne in mind that flax is not suitable for operating pipelines for operation at a temperature of more than 90 degrees, because it flashes over time, losing its properties. You can use the Tangit Uni-Lock thread or its analogue. Packaging on a blister confidently declares that 20 meters will be enough for sealing of 50 compounds for a 1/2 inches thread. Analogue - "Plot" at the same cost has 50 meters and is sold in almost any Laua-Merlen type store.

It is possible to use a polyamide thread in combination with silicone lubrication. The branded Tangit Uni-Lock consists of a polyamide thread and silicone, so you can easily save, taking a conventional thick polyamide thread and silicone or sanitary lubricant in any construction store. Linen jute rope Or a similar analogue made of vegetable raw materials, on the occasion of purchased in a business store, spending about the same 50 meters about the same amount.

When using silicone sealant, it is necessary to keep in mind that it solidens pretty quickly, so after a short period of time to adjust the connection will no longer succeed, such a sealant simply breaks inside the thread. For these reasons, the sealing filler should not harden or wash away.

Another interesting point - silicone sealants On acetic basis, it is caused by corrosion of a metal, it is necessary to consider when choosing materials.

The easiest way to decide what is suitable for sealing, and what is not, it is necessary to pre-experiment.

How to get out?

For professionals, this is a thing of habits - who wures the cross-cross, who exactly follows the instructions in detail in the instructions, while most importantly - you need to turn it tightly, so that the thread is completely closed by the material used, in this case nothing will penetrate. However, wound against the thread thread may be damaged when screwing the nut.

To wind up flax, you need to separate a small strand in one or two matches, smooth it, choose and throw away smallpox. You can twist strand into the lace. Then very tightly winding it on the thread, ranging from the edge of the thread, so that the carbage groove is completely closed. After that, it will be necessary to take a plumbing paste and rotational movements to smear it on Len. If everything was done in the process of work neatly, then everything will definitely. It will only be left to spin the connection by attaching a slight effort. If the nut at the same time is easily spinning, it means that a small amount of flax was wound up, or it turned out too much a gap between the inner and external thread. It will be necessary to disassemble everything and rework. If the work was performed correctly, the flax will not hang out, and it will be a reliable and hermetic connection.

Tangit Uni-Lock's thread is enough to hide the cross-crosswise either to float on a thread on 6-8 revolutions and combine the details among themselves - on this work will be completed.

With a self-name version, the polyamide thread needs to be coated and deceived by plumbing paste or silicone lubricant. It is possible to pre-impregnate with silicone lubricant all the polyamide thread motility, after that it is winding it on the connection and connect the details. You can then put in plastic packaging, so that it does not bother, do not dry, and nothing superfluous to it.

The linen rope should be disconnected by two lace, cut off 40-50 cm from it, climb on the thread, lubricate the plumbing paste and spin the obtained connection. Understand that it is better to use in the process of work - a synthetic thread - Tangit Uni-Lock or another analogue - can only be available in the presence of appropriate experience.

1. Pakly destination and how it works.
2. Varieties of sealing materials.
3. Sealing technique pipe thread Packs.
In the sanitary work, the passage is used to seal pipes and transitions connected by means of thread. It is mainly made, from flax waste and is a rough fiber small sizes. If you correctly apply the pass, protection against leaks will be provided throughout the entire service life of the pipeline. Answering the question of how to wind the passage on the thread, it should be said that the quality of execution prevents the risk of the occurrence of leaks in the plumbing system.
There is a gap between the threaded compounds through which the water is unhindered outside the pipeline. If it is present in it properly laid Pacle Plot, then the gap becomes less, and in the process of water penetration, in such a connection, the flax will swell and the leak stops.

Varieties of sealing materials.

To basic materials that create a hermetic layer between threaded compounds include:
- Pacle Plumbing;
- Fuma Ribbon;
- Liquid Fium.
Silicone is used as additional material to the package, but by itself, because of its properties, will not be able to provide reliable protection Connections from leaks.
Foney is a winding for a thread consisting of teflon tape, not wetted by water and creates a water-repellent layer in connections.
Liquid Fium - single-component sealant of blue colorWhen contacting with air slowly solidifies and forms a sufficiently durable and dense aggregator, which prevents the expiration of water from the system. But, if using the above-listed materials of the water pipes, it can be done at once, then after using a liquid fum, before checking the system, you need to wait a certain time depending on the diameter and ambient temperature.

Methods for sealing pipe thread packles.

High-quality thread winding is carried out using the following materials and tools:
- pipe lever keys in the amount of two pieces;
- Pakli plumbing;
- Fume ribbons.

The procedure for obtaining high-quality hermetic threaded compound Consider on the example of the combination of a cape nut (American) with outdoor thread 1 inch and check valve.
With pacles, we separate a strand long, approximately 5 - 7 turns of diameter of 1 inches and the density of the specified in the photo.

The resulting workpiece we apply to the beginning of the American connecting element, while its thread should be directed at you, and we wind clockwise, along the turns and back. The end of the package is summarized to the beginning of the thread and fingers, clockwise, smooth it. As a result, it should be in the photo.

Then, we wake the FMU clockwise on this item so that it completely overlap Len Santechnic and lay on it in 2 - 3 layers.

Teflon tape does not give a pacle to turn and move from the part. I'm caught up with an American check valve And with the help of keys, we produce their tightness before the occurrence of a tangible load.

Such a combined winding of the thread, with the appropriate skill, almost always provides a reliable bunch of two detachable elements of the pipeline. When all components of the system are assembled, it is necessary to produce its crimping at a pressure approximately equal to 1 bar and inspection of all threaded compounds for leaks.
When using poor-quality parts, the amount of winding should be slightly reduced, since in the process of flax raising, efforts arise that may damage the part.

How to wind the pass (flax) on the threaded connection (video)

When assembling any threaded compound, be it for gas, water supply or heating, you can not forget about the tightness of the entire system. Experienced plumbing is armed with a whole arsenal of funds and tools, and beginners in this matter need to carefully master the most basic techniques and approaches. One of the examples of basic knowledge is the question: how to wipe the passage to the thread? Well, we'll figure it out!

Preparatory stage

Before winding the flax or pass on the thread, you need to prepare the surface of the connection and determine the desired number of packle. Screw the fitting on the thread as it is, without winding anything. This will help determine how much it will be necessary to take a pacle.

If the carving is smooth and smooth (in the case of factory cutting, most likely, it will be), for better clutch it is recommended to apply notches on the turns. This will fit a waterproof key, naphthyl tribbon or ordinary pliers; All you want to do is to apply notches across the thread, while not too diligent. This is done in order to prevent the slide of the pacle on the turns of the thread.

Notches should not be too deep, you do not need to literally prey the metal (watch the video). From how the package is correctly wound, the reliability of the compound in the future will depend. If we put too little and rarely - it will flow, the excess amount may be much more dangerous - too tightly the wrapped area can burst with increasing temperature (as you know, the metal is expanding when heated).

Get ready to winding

From the total beam, a small number of packles should be taken, while the fibers must be smooth, smooth, without nodules and breaks.

Purchase must be twisted into the rope of such a thickness so that it (thickness) is equal to the carving step, i.e., filled with a depression between the turns.

We carry out the winding from the inside edge of the thread;

there are several ways how to wind up the pass - for example, some advise to start winding with an indent and then overlapping the fibers so that they keep them better (see video).

But for beginners it will easier to get out directly from the edge.

So, putting the end of the linen rope to the first turn, make winding in the direction, reverse the turn of the twist - that is, clockwise, if the thread is the right (in the overwhelming majority of cases it is also).

You need to wind tight, but not too abundantly - two layers will be more than enough. As soon as they wound the passage on the thread, you should, without releasing your fingers, impose a paste for fixing. This is often used silicone, paint or glue, but personal experience We recommend paying attention to Unipak - this paste is more neutral with respect to the metal and does not have a taste and smell, which will help avoid problems when installing the water supply.

Flax (Pacle), FMU or Plumbing thread?

The usual package is an old but proven to the plumbing, in fact this is a "grandfather's way." A package is suitable for winding and other works. The modern industry offers alternatives as fluoroplastic (FMU) tape and ready.

While their use may be more convenient for a number of reasons, Len has its advantages: It is more environmentally friendly in comparison with fluoroplastic and much more accessible than a special plumbing thread. It is quite possible that in the future we are waiting for new solutions that will be displaced Len, but as long as knowledge of how to wind the passage on the thread will never be overwhelmed for the economic person.

The question of how to wind flax on the thread occurs in many people, it is also often encountered with the task of choosing between FUM tape and flax. Each variant is preferable for different situations. In this case, in some cases they can be interchangeable.

Benefits

It is a standard seal for it can also be found called Pakle. It has many advantages, among whom it is worth noting the following:

• Resistance to mechanical exposure. This material is optimal option For sealing plumbing reinforcement. When using it, it is possible to adjust the preservation of tightness.
• In the process of wetting flax increases its volume. That is, you can not worry if a small leakage occurs after the connection is completed, as it will be easily eliminated. The material begins to swell from the impact of moisture and, thus, overlaps to flow.
• Universality. The correct winding allows you to use various types for connections.
• Low cost. Compared to other seals, this option costs significantly cheaper. The main thing is to choose a high-quality winding, it should be bright, implemented in the form of bay or pigtails, and there should be no lumps and splashes.

Features

Despite the existing advantages, it did not cost without some points complicating the application:

• It is necessary to be careful in the process of working with bronze and brass, as it is possible to damage the thread when winding a thick layer.
• Before use, the thread must be carefully prepared. Today, the market presents fittings with a thread designed for linen winding. They can be determined by special notches. With their absence, you can use the pliers or file. Shells prevent flax knocked down and his slipping.
• Before winding flax on the thread, it must be treated with suitable compositions - it can be paint on an oil basis, silicone, sealant or solidol. Since this winding is organic materialIt is subject to the development of grinding processes when contact with water and air. The latter is annually in heating and water supply systems during preventive work or repair. Special compositions allow you to prevent the destruction of the material.

Tools for processing

Some special compounds may complicate the disassembly of the compounds, the need for which occurs when the leakage appears, connecting new elements or during the replacement of some parts. Paint and silicone contribute to gluing elements and, as a result, the difficulty of separation, in some cases it becomes impossible. In the absence of related tools or illiterate winding on steel parts, similar problems appear caused by the occurrence of corrosion damage on the connection.

Linen pack should be wound only in accordance with the established rules. To begin with, it is processed suitable toolAlso prepared a thread for it. Direction when winding should go through thread turns. Next, the remaining part is derived from its limits and is stretched, at that time the connection is screwed and delayed. How many flax wove on the thread? This can be determined by the density of the fitting on it.

What is better: flax or fum-ribbon?

Special requirements are presented to the materials used to organize hot water. They concern the means used for winding. Due to the high temperature of the liquid in the pipes, the winding must have high tightness and resistance to temperature effects. Flax meets similar requirements, while FUM tape is not the most best Material. When the connection, it is divided into a plurality of fibers that seal emptiness and prevent water leakage. High temperatures that are characteristic of water supply with hot water and heating system, Specify the fibers. Because of this, the risk of leakage appears.

As for other characteristics, it should be noted that the package of linen costs cheaper than fum-ribbons, even subject to the use of material for processing. If the difference is not so noticeable in minor work, then you can get significant economy. But at the same time, the tape accelerates work. Thus, it is impossible to unambiguously say that it is better: flax or fum-tape, as each material is suitable for various tasks.

Combination of two materials

In some cases, a combination of flax and fum-ribbons are used to obtain a better connection. Perhaps two options: flax is covered with several ribbons, either both materials are wounded in turn. Despite the effectiveness, such a method did not acquire distribution due to the features of winding conditions.

Preparatory work

Before the connection is prepared. It is necessary to prevent the material from knocking or climbing smooth surface. If the flax does not hold on to the installed place, the degree of sealing will be extremely low. For fixing the fibers are applied special jar on the turns. They can be cut with a handwheel for metal, a file or dad. In the absence of such tools, you can use the pliers and, holding the thread as much as possible, to surpassed it - should turn out in a circle of turns, small jar. Also, as mentioned earlier, you can purchase fittings that are specifically made for the plumbing pane.

How to wind flax on the thread: instruction

Fibers are separated by small strands. It is worth noting the need to carefully select the thickness of the strands, since the winding must have an average thickness. When discovery of lumps or foreign elements, they must be removed. Plumbing use various options, For example, winding a strand or woven into a pigtail. This is necessary to simplify the work, while the quality of the connection remains unchanged.

Further santechnic Len.previously processed special composition, wounds on the thread. You can also first apply the composition to the surface, then wind the material, and on top to distribute the additional layer. The effectiveness of both options is on the same level.

Regardless of the method used, the pacting is wound according to the direction of the thread. The first round should act as a castle: for this, it is superimposed by the cross, at this time one side of the strands should be clamped. The compaction of the thread of flax should be the most tight, and between the turns there should be no intervals. Then the strand is supplied to the edge of the thread and is glued using a suitable material.
