To seal threaded connections of plumbing communications, it is rational and convenient to use polyamide or fluoroplastic threads impregnated with special lubricants, which give the threads moisture resistance, and also protect the outer surface of the thread from corrosion. In addition, this is a modern, less labor-intensive and reliable solution to the issue of sealing threaded connections in plumbing.

For proper and high-quality sealing and sealing of a threaded connection, it is necessary to strictly follow the technological process for performing this operation, which otherwise will lead to leakage of the connection and its short service life. I place the tip of the thread at the beginning of the thread on the pipe, so that the thread lies completely in the groove between the ridges of the thread to its very bottom.

In this case, the fundamental factor is the direction of the thread. It is worth strictly considering that the thread is wound along the thread. In plumbing, this is an important factor, since depending on the connections made and connections of sanitary fixtures to water supply and heating communications, there are both left and right thread directions. Otherwise, when twisting the parts, the thread will simply be squeezed out of the connection by the screwed part. Having decided on the direction of winding the sealing thread, I lay it in a uniform, dense first layer along the entire length of the thread. Then, in three stretched turns, I return to the beginning of winding the thread, that is, again to the beginning of the thread, and repeat the operation.

By such repetitions of winding, I achieve the required layer of sealing thread sealant, which allows the operation of screwing up the threaded connection to be carried out with interference. Having finished winding the last layer of seal, I return the thread to the beginning of the thread and cut it with a sharp knife. This action is important so that when starting the connection, the wound part initially tightly presses the end of the thread and does not allow it to relax further. Since depending on the manufacturer of the thread, its diameters vary significantly in relation to each other, it makes no sense to recommend the number of wound layers and you only need to focus on the degree of density of the parts being twisted.

Winding the thread crosswise, as in the instructions

The uniform and dense feeling of force during this operation indicates the result of a high-quality connection and optimal adjustment of the thread. When twisting the parts of a threaded connection with an adjustable or open-end wrench, you immediately feel a reasonable force during this action; the parts should in no way be screwed together by hand. Protrusion and squeezing of the thread from the connection indicates an excess of sealant and is fraught with the formation of a defect in one of the parts being connected; often the screwed part can simply burst. The lack of effort when screwing up indicates a lack of application of the sealing thread to the thread, and such a connection will definitely not be airtight and will be guaranteed to leak.

The apparent simplicity of this action at first glance actually requires a serious approach to its implementation. After all, the reliability of the entire system and the absence of emergency situations during its further operation depend on the quality of sealing.

What can you say about sealing materials for threaded connections? Experts divide them into three groups. The first is materials of plant origin. These include flax strands in various combinations - with red lead on drying oil, with paint or sealant. The second is first generation polymers. This is the well-known FUM tape, non-drying sealants and solvent-based sealants. The third is second generation polymers. The most modern, reliable and durable materials. This group includes anaerobic sealants and sealing thread. We'll talk about it today.

Universal sealing thread-sealant

The synthetic sealing thread for threaded connections consists of 280 polymer microthreads and is impregnated with a special sealing compound. All components of the thread sealing composition are balanced and ensure absolute tightness of the connection. Silicone, which is part of the impregnation of the sealing thread, deserves special attention - it protects the threads from corrosion.

The universal thread for sealing threaded connections is simple and easy to use. It is completely ready for use; to work with the sealing thread, you do not need to look for or purchase third-party materials and tools. The thread is packed in a convenient box, with a knife for cutting.

The sealing thread is applied within a few seconds. The technology is intuitive even for a beginner and does not raise any questions - the first turn of the thread is fixed closer to the edge of the thread, and the rest is applied crosswise. Upon completion of the sealing winding, the connection is twisted onto the thread.

If you need to adjust the connection, an adjustment of up to 180° is possible when sealing with thread.

This means that the use of the latest generation of sealing materials allows you to adjust the connections, which was impossible when sealing, for example,.

Advantages of sealing thread for sealing threaded connections

Fast and easy twisting

In the shortest possible time you get a high-quality connection. You don't have to wait for the sealant to cure or "set." The sealing thread seals instantly.

Safety and reliability

The thread is a sealing sealant - a non-toxic material that does not require paint, solvents, or impregnations to work with. Synthetic sealing thread does not absorb moisture and does not swell, and like synthetic material it is not subject to decomposition.

Unpretentious in preparation for work

Thread is used on dirty, wet and rough threads. Winding minimizes thread imperfections, which has a better effect on the quality of the connection. The thread is suitable for very fragile and thin-walled threads, used at low ambient temperatures.

Versatility

You can use pipe sealing thread for use in drinking water, natural and liquefied gas systems. She has all the necessary approvals and certificates for this. Another advantage of the sealing thread is that after finishing twisting and installing the system, you do not have to wash your hands of any remaining material and tidy up your work area.

Sustainability and aesthetics

Such a joint sealant as a thread is resistant to vibrations, mechanical damage, shock and temperature changes. The connection assembled with the thread looks very neat - there are no smudges or protruding fibers from this material. The connection with the sealing thread can withstand pressure several times greater than linen winding or FUM tape.

Of the minuses, only one can be noted - sometimes it is wiser to prefer an anaerobic sealant to the threads. This is relevant when a smooth or canonical thread is selected for the seal. The thread may slip, but the sealant gel hardens and blocks any movement.

The sealing thread also has a number of advantages:

the price of the sealing thread is close to the price of flax strands and FUM tape (based on one connection)
wide operating temperature range - from -60 °C to 150 °C
guarantee against leakage and pipe rupture - 20 years

So, in order, the information is confirmed by test reports from leading manufacturers of polystyrene concrete, I drew a conclusion for myself and wrote it at the end of the commentary. MOISTURE RESISTANCE and HYGROSCOPICITY This is the most important property of any building material, especially in areas with high humidity. The higher the moisture resistance of the material, the more durable, stable and warmer it is. Polystyrene concrete absorbs no more than 6% moisture from the atmosphere; it can be exposed to the open air for an almost unlimited time. STRENGTH Due to the super-strong cement-polystyrene matrix, polystyrene concrete has unique strength characteristics. This material is so durable that a fall from a five-story building will not cause significant damage to the block. FIRE RESISTANCE Polystyrene concrete does not burn; it is able to withstand enormous temperatures caused by fire, due to its unique thermal conductivity coefficient, and does not allow heat to penetrate deep into the wall. Flammability class NG. Fire resistance class EI180. DURABILITY The service life of a house made of polystyrene concrete is at least 100 years. Over the years, the strength of polystyrene concrete only increases. FROST RESISTANCE Tests for frost resistance and the amplitude of temperature fluctuations from + 75°C to - 30°C were carried out on 150 freeze-thaw cycles without loss of integrity and heat-insulating ability. THERMAL INSULATION It has long been recognized that polystyrene (foam) is the best thermal insulator in the world; it is warmer even than wood! A house made of polystyrene concrete does not require insulation: it is cool in summer and warm in winter. SOUND INSULATION Polystyrene concrete provides the best indicator for noise absorption, 18-20 cm dampens sound from 70 decibels. Consequently, a house made of polystyrene concrete has a special comfort: noise from the street and inside from neighboring rooms and bathrooms is not disturbing. ECONOMICAL The cost per square meter of a finished wall is cheaper than other materials. Due to the high level of heat retention, walls made of polystyrene concrete can be built 25% thinner than those made of alternative materials (aerated concrete and foam concrete) and 4 times thinner than those made of brick. Saving on wall thickness leads to overall savings on the construction of the box (foundation, roof and walls) of up to 50%. At the same time, the quality of the house will be even higher, and the house itself will be warmer. EARTHQUAKE RESISTANCE Seismic resistance 9-12 points. Polystyrene concrete has not only compressive strength, but also the highest tensile and bending strength. Therefore, polystyrene concrete is considered the most reliable and earthquake-resistant material. LIGHTWEIGHT A large-sized block of 200x300x600 mm does not exceed a weight of 17 kg, which facilitates the work of a mason and reduces the time for laying walls: it replaces 20 bricks in volume, and is almost three times lighter in weight. ANTISEPTIC The additive used in the production of polystyrene concrete does not allow insects and rodents to enter the walls, and prevents the formation of mold and mildew, which have a negative impact on health. VAPTOR PERMEABILITY Walls made of polystyrene concrete “breathe” similarly to walls made of wood, and there is no danger for them from condensation and waterlogging. This ensures a comfortable environment in houses made of polystyrene concrete. PLASTICITY Plasticity is the only material made from cellular concrete that allows the production of window and door lintels; its flexural strength is 50-60% of the compressive strength; for concrete this parameter is 9-11%. CRACK RESISTANCE Polystyrene concrete, due to its elasticity, is incredibly resistant to cracks. And this guarantees a long period of preservation of the interior decoration and durability of the entire house. TECHNOLOGY High speed of construction of wall structures due to the lightness and convenient geometry of the blocks. They are easy to saw and groove, making it possible to give the building material any geometric shape. ENVIRONMENTAL FRIENDLY The International Building Code (IRC) classifies polystyrene as one of the most energy efficient and environmentally friendly insulation materials. Thus, polystyrene concrete has a lot of undeniable advantages over materials such as expanded clay concrete, autoclaved and non-autoclaved aerated concrete, foam concrete, wood concrete, etc. The disadvantages of polystyrene concrete only appear if the brand is chosen incorrectly and the technology of masonry and preparation for interior finishing is violated. We can say with absolute certainty that there is not a single significant advantage for materials such as aerated concrete and foam concrete over polystyrene concrete. At the same time, polystyrene concrete significantly surpasses them in key characteristics.

In this article we will tell you in detail how to properly pack threaded connections with pipe winding. Record thread is very convenient to work with. It is ideal for urgent repairs or quick installation, because... the connection to be forged does not require preliminary preparation. The threads may be damp, dirty, rusty, or even partially broken. If you know how to wind the thread correctly, then absolute tightness is guaranteed.

How to rewind threads correctly

The end fits into the thread as close to the edge as possible and is secured with an overlap with the first turn. Next, the thread is wound crosswise, crossing the threaded grooves. It is necessary to ensure that the winding is tight, otherwise, during the process of twisting the connection, the thread may be squeezed out of the thread and not ensure the tightness of the fitting.

You can always order high-quality Russian-made sealing thread at a reasonable price on our website in the section. You can also use the "" section, where you can see the address of the store closest to you where you can purchase PCT products.

To protect the thread surface from corrosion, the Record winding is impregnated with a special silicone paste.

When it is wound, you can begin assembling the connection; during the twisting process, a small part of the thread may be squeezed out of the thread, there is nothing to worry about, the main thing is that the main part of it remains in the thread. Excess thread can be cut off with a stationery knife.

Another advantage of working with Record winding is the ability to adjust the assembled connection. That is, the already assembled connection can be adjusted at an angle of up to 180 degrees, unscrewed or tightened without losing its tightness. This is convenient when some kind of system is being installed and during the assembly process the master slightly twisted the ball valve. If the thread was swayed by the Record winding, the tap can be turned back to the desired position and not worry that the connection will leak after starting the system.

If you disassemble the connection, you can clearly see how the thread fills the threaded gap.

The Record pipe winder consists of more than 280 microfilaments. Thanks to this structure, connections sealed with this thread can withstand various loads: shock, vibration, expansion/compression under the influence of temperatures, and maintain absolute tightness under such conditions due to the redistribution of microthreads in the thread.

Now you know how to properly wrap threaded connections with plumbing thread and will always achieve a professional result.

Sealing threaded connections in heating, water and gas supply systems is perhaps the most important task for a plumber or gas equipment installer. Not only the normal functioning of the system, but also the safety of the structure in which it is installed depends on the quality of the work performed. The threaded connection itself is very strong, but it is not capable of holding liquid or gas without special treatment. There are quite a few means for sealing, one of them is a special polymer thread for sealing threaded connections, which will be discussed.

“Moment Germent”, length 15 m.

Application area

Thread sealing thread (or sealing thread) is a new generation universal polymer sealant used for both metal and plastic pipes for various purposes. It is made of two types of material: polyamide or fluoroplastic.

"SantekhNit", length 50 m.

Polyamide is a low-wrinkle synthetic fiber with an upper temperature limit of 130°C. Thread made from this material has increased wear resistance (10 times more than cotton) and resistance to many aggressive environments. When wound onto a thread, it can withstand a water pressure of 16 bar and a gas pressure of 8 bar.

Sprit sealing thread complete with an additional 50 m skein.

Fluoroplastic is a fluorine-containing polymer with an upper temperature limit of more than 200°C. It is characterized by plasticity, heat resistance and high adhesion. Even more resistant to aggressive environments than polyamide. Polyamide thread, when wound on a thread, can withstand pressure up to 30 bar.

"Tangit Uni-Lock", length 80 m.

Any seal for threaded connections is impregnated with a special lubricant to ensure the reliability of the threaded connection. It is hygienic, does not decompose and prevents the development of corrosion. The connections assembled on such a thread are easy to adjust (adjust), which is very convenient if you need to install a tap, pressure gauge or fitting in the desired position.

At the same time, there is a danger that with a sharp change in temperature and increased vibration, the plumbing thread may become deformed, which will lead to a leak of liquid (gas). For this reason, professional plumbers of the Soviet school often prefer - an old, proven product, if handled skillfully, will never fail.

Winding technique

No special preparation of the thread is required before winding (you don’t even have to remove the rust - the connection will not be damaged). The only condition is that the thread must be intact and preferably have a pitch of 14 threads per inch. With a larger pitch (11 threads per inch), there is a real danger of thread breakage due to its small thickness.

"SantekhNit", length 20 m.

The part (pipe, coupling, fitting, etc.) is taken in one hand, and the thread itself is taken in the other to seal the threaded connections. Winding begins from the beginning of the thread and proceeds further along the thread obliquely clockwise. At the beginning of the thread, you should wind a thicker layer, since when tensioned, the thread will “go” deep into the thread. This will ensure uniform distribution of the sealant along the length of the joint.
