Tape for sealing pipe joints. Modern waterproofing materials for pipes

Pipelines are exposed to various factors: moisture, aggressive environments and ultraviolet radiation, which significantly reduce their service life. To protect highways. This material must be applied to pipes that are laid underground, outdoors and in rooms with high humidity. When passing through the pipeline of the heat carrier and hazardous liquids, additional thermal insulation is used. Insulating tapes are used in all sections of the pipeline, including in places where fittings are inserted and at joints.

Waterproofing materials

There are ready-made pipe protection solutions on the market that provide reliable waterproofing of the pipeline. Correct determination of the optimal type of pipe insulation tape is a guarantee of reliability and durability of the insulation layer.

The main criteria that determine the choice of waterproofing tape:

  • product material;
  • temperature regime in the system;
  • place of installation of waterproofing;
  • temperature environment;
  • carrier characteristics and operating pressure in the system.

The choice of tape for waterproofing pipes, the material for their primary processing and the type of additional protection is based on the initial data.

Shrink Tapes

Heat shrink tape is a two-layer insulating material that is designed to protect pipes and difficult sections of the pipeline. The setting of the material occurs at a temperature of +80 ℃ - +100 ℃. The laying technology requires the use of a special tool and is carried out by qualified specialists with skills in working with heated materials.

Joints, seams and joints with fittings are processed using heat-shrinkable cuffs. This material is used when carrying out current repairs of areas where the tightness of the system is broken. The base and the adhesive composition are two inseparable layers included in the design of the cuffs. The outer layer is designed for protection and is made of polyethylene, and the inner adhesive layer is made of vinyl acetate and ethylene, which have a low melting point. Processing pipes with this insulating material increases the service life of the line by 3 times.

The pipe insulation tape is suitable for processing heat-resistant materials such as copper, steel, cast iron. It cannot be used to seal PVC and plastic pipes.

Tapes based on bitumen and PVC

Roll materials consist of three layers: a bitumen-based compound, a base and a film with adhesive properties. The material in the roll does not stick together due to the use of a protective polyethylene film. The waterproofing properties of tapes for pipeline insulation are provided by asmol mastic, which is securely fixed on the surface of the material being processed. The outer layer is made of PVC film, which protects the mastic from moisture.

A universal material that has no restrictions on the material of the pipeline. It can be applied not only to cast iron, steel, copper, but also to PVC and plastic pipes. The maximum pipe diameter reaches 1.5 m. The service life of the material is from 35 years. Application on the treated surface can be carried out at a temperature of +10℃.

Bituminous tape is typically used to insulate underground pipelines. The use of this material outdoors is limited due to the possible overheating of the protective layer. The surface of the pipeline requires pre-treatment. A primer layer is preliminarily applied, and then the waterproofing is wound.

Adhesive tape size: length - 3m/10ft, width - 25mm/1”, thickness - 0.5mm/20mil.

Degree of electrical insulation: 800 Volts.

Material: silicone.

Permissible temperature range: from -60 to +260 degrees Celsius.

Withstands the maximum allowable pressure: up to 5 bar.

The tape does not support combustion. Differs in water tightness and moisture resistance.

Silicone adhesive tape is designed for emergency repair of hoses, pipes, insulation of electrical connectors and terminals.

Once wrapped around the hose, the tape vulcanizes and becomes part of the hose, making the repair site resistant to repeated damage.

Can be applied and fixed on wet, dirty and greasy surfaces.

In case of unforeseen emergencies, it can be used for medical purposes - as a tourniquet to stop bleeding, or fix limbs in case of injury.

Designed for storage in vehicle, or as part of a set of equipment for the repair of hoses and pipes.

Latest reviews from Aliexpress

46 days to Moscow time from the date of payment! Packed in a cellophane envelope. We have such a tape in Leroy costs 450-500 ?. After winding around the hose, it vulcanizes and becomes part of the hose! The perfect solution for home and garden! I didn’t remove the star for the delivery time, because the price tag is good and the tape itself is of excellent quality!)

Very surprised by the quality of the film. They thought that she would be barely alive, but it turned out that she stretches very well and accepts quickly former form. Very soft. We did not even expect that for such money we would buy a high-quality film from leaks.

A good thing! For those who do not understand how to use it, you just need to understand how this tape works. The tape is designed for winding with an overlap, in two or three layers. Do not forget to degrease the surface on which we apply the tape. With stretching and subsequent heating (the warmth of the hands is enough), the polymerization process is activated and after 10 minutes, we get an almost monolithic, rubber structure. It will be impossible to separate the layers after that. Follow all these principles and you will succeed)

The goods came exactly 2 months to Kazakhstan! In general, the tape is similar in appearance and to the touch - like double-sided tape. . . I don't know how it will work. . . The protection was already ending, I wrote to the seller to extend it, but he ignored it. . . Minus 1 star for that!

and so the delivery from the seller is fast for 20 days, I took 2 at once, just in case, the price for 2 pcs 3. $ 14 stretches well, somewhere 3 times it sticks to itself well, so I think that it should fulfill its functions

The order came in two weeks, everything is fine, I have not tried it yet, I think everything will be fine. Thank you seller for fast shipping and well packaged item!

Delivery was very long, almost two months. Package torn, one clip was lost. The seller needs better packaging. The tape itself has not yet been tested for leak retention. I'll write back later.

The packaging is good, the product is not damaged, it seems larger in the description, the width is 1.3 cm. Haven't used yet. Thank you seller.

everything according to the description has not yet been tested in practice, it’s better not to come in handy, and let it be at hand

Delivery is fast - reached Kyiv in 16 days. Haven't used it in practice yet. Thanks to the seller for the efficiency.

Tape for pipes is a modern sealant designed for use in water supply, sewerage, gas pipeline systems, as well as critical systems with aggressive and high-temperature environments. The tape is convenient, does not require additional preparation of the workplace, is indispensable in a situation of emergency pipeline repair and in the absence of sealing experience.

Types of tapes and applications

The sealing tape for pipes differs in composition, size, color, but most importantly - in the scope and method of winding. talking plain language, tapes are for external and internal use. "External" tapes are wound over the pipe, they are both additional and main sealant. Tape for pipe joints is relevant for detachable connections without threads and flanges, as well as for sealing pipe bends, tie-ins, plugs, fittings and other line elements.

"Internal" tapes are applied to the thread, i.e. sealing of the site occurs from the inside. For threaded connections, a plumbing tape is used, which is much smaller and thinner than the external sealing tape and has slightly different technical and operational characteristics.

Let's explore them in more detail...

Sealing tape for pipe joints is a multi-layer self-adhesive material, usually with a bitumen-polymer composition. Differs in waterproof properties, protects a pipe from corrosion, mechanical, chemical, temperature influence, excludes leaks.

Depending on the temperature of the transported medium and the place of sealing, there are:

summer ribbon

Operating temperature range - up to +300˚С. Suitable for high temperature environments, applied to areas located underground or indoors.

winter ribbon

Works at a temperature of -200˚ to +100˚С. Designed for outdoor work when laying the main or municipal pipeline.

heat resistant tape

Retains its properties at extreme temperatures up to +1500˚С. Used for sealing critical systems, including oil pipelines.

Polymer-bitumen tapes are effective in laying heating mains and sealing not only the joint, but also a large straight section of the pipe. Reliable, durable, environmentally friendly and convenient. Due to the elasticity and pliability of the material, it is possible to seal the required section the first time and quickly, which is important when the construction or repair of the pipeline is limited.

Apply the sealing tape to the cleaned, dry pipe with the adhesive side inward. Winding is carried out according to the type of spiral overlap. It is important that the tape fits snugly around the pipe, does not bubble and lays down smoothly. Before each turn, the tape is slightly stretched and laid with a wide overlap, capturing half of the previous turn to make a double layer.

The service life of the outdoor belt is about 30 years. This is an adequate figure for main pipelines that need 100% sealing.

FUM tapeand plumbing thread

These materials are intended for sealing threaded connections of plastic and metal pipes. Widely used in domestic pipelines in the assembly and repair of gas pipelines, water pipes, installation of plumbing equipment, connecting household appliances ( washing machines, dishwashers, gas boilers, etc.)

FUM tape:

  • Varies in width and thickness
  • Effective for hot and cold water systems, operating temperature range is from -70 to + 200-250 ˚С
  • Resistant to pressure up to 100 atmospheres, copes with pressure surges in the system and water hammer
  • Most effective on plastic threads
  • Suitable for temporary connections
  • Shows good results as an alternative to rubber gaskets and O-rings

In addition to the fact that a high-quality tape is not easy to choose, two main disadvantages are distinguished from it - uneconomical consumption and the complexity of winding. Anyone who works with FUM for the first time needs to make several test connections to get used to it, find out the number of turns for a particular thread, measure the flow rate and select the appropriate tape size for different types works.

Another feature of sealing the connection with the FUM is the impossibility of adjustment. If, during the assembly or operation of the thread, its unwinding, albeit small, is expected, there can be no question of tightness. That is why the FUM tape is chosen for simple non-hazardous connections.

In addition, the FUM tape does not tolerate vibrations. If the connection is periodically subjected to it, sooner or later it will leak.

Winding Record is also a variant of the sealing tape. This plumbing thread is designed to seal threaded connections in natural and liquefied gas systems, cold and hot water, drinking water and compressed air. With the help of this thread, a wide range of domestic work related to the assembly of engineering systems, installation and connection of equipment is performed. including something as complex as pumping station or heating double-circuit boilers.


The Record thread is much more convenient than the FUM tape, primarily because it is wound randomly - along the thread or crosswise. The simplest instruction is clear even to a beginner, besides, the thread does not slip and “does not wobble” on the thread. Due to the impregnating composition, it adheres tightly to the sealed surface.

Winding Record:

  • Instantly seals any connection
  • Does not require preparation and even thread cleaning
  • Protects the joint from corrosion
  • Does not contain plant components, synthetic and hygroscopic
  • Suitable for fine and thin-walled threads
  • Works at temperatures from -60 to +120 °C

The shelf life of the connection with winding up Record is 20 years. If this seal is used to assemble a pipeline with detachable threaded connections, then the need for additional external sealing disappears. Tests have shown that the winding can withstand a pressure of 40-50 atmospheres and can be used in critical systems - for example, automatic fire extinguishing systems.

You can rewind Record, and directly from the manufacturer and at an affordable price!

Greetings, my dear readers!

Many people know that when creating and repairing various engineering communications, it is important to reliably seal all elements. The reliability and efficiency of systems depends on this. Today I will tell you how to choose a sealant for pipes for water supply, sewerage, heating and smoke removal.

Category No. 1: materials for sealing water and sewer pipes

For sewer and water pipes, there are several types of seals.

Sealing tapes

Self-adhesive tapes specially designed for sealing pipe joints are a modern means of sealing. They have such merit.

  1. Self-adhesive films are easy to use and have high efficiency.
  2. Sealing tapes on a durable polyethylene base have good performance characteristics.
  3. They are universal, they can be used to seal different types of pipelines (sewer and water), because they have anti-corrosion and dielectric qualities.
  4. Tapes can be used not only for sealing pipe joints, but also for sealing system elements: tie-ins, plugs, corners, etc.
  1. Prepare its surface for winding sealant: it must be cleaned of dirt, dust and dried.
  2. When applying the tape to the pipe, make sure that it is constantly stretched, in addition - do not allow the formation of wrinkles and folds.
  3. Wind the film, creating an overlap of 50 percent in a spiral. As a result of this, the entire surface to be sealed should be under the two-layer protection of the tape.

Plumbing Tape poorly resistant to ultraviolet radiation. As a result, if the sealed section of the pipeline is exposed to the sun, it should be additionally protected from ultraviolet radiation over the film.

Silicone compounds

Silicone-based plumbing pipe sealant is another common sealant. Rubber silicone compounds are a composite of different substances providing high quality sealing. They have good adhesion to the surfaces to be sealed and do not require pretreatment with a primer.

I want to warn you that according to the type of hardener, silicone sealants for sewer pipes are divided into the following types:

  1. acid compounds. Their price is relatively low. However, they cannot be used to seal certain surfaces that may come into contact with acids.
  2. neutral counterparts. They are universal and can be applied to all types of materials from which pipes are made.

With the help of silicone sealants, both metal and plastic pipes are sealed, but only sewer pipes.

Following the vulcanization of the silicone gel, after its application, it is converted into a material similar in quality to rubber. This process is directly affected by the moisture content in the air.

At the moment, they are of the highest quality, which is why sealants of the Tytan, Moment and Sinicon brands are popular. They are used not only for sealing joints of metal and plastic pipes, but also for repairing fistulas and cracks.

Let me show you how to use them:

  1. Make sure the surface is dry and clean before sealing.
  2. Next, carefully distribute the silicone gel along the junction of pipes or elements of the system.
  3. The composition should not be smeared additionally. Apply it in 2-3 layers, slightly going beyond the borders of both sides of the joint.
  4. It is highly undesirable to moisten the pipe not only before and during work, but also until the polymerization of silicone is completed.

Squeezing and distributing the sealant is extremely simple - using a special mounting gun. If not, you can use a regular hammer.
Insert its handle into the tube and press this kind of piston.

Epoxy resin

It serves, as well as adhesives based on it, the most used means for water and sewer pipes:

  1. In water supply and wastewater systems, epoxy resin is used for cast iron and ceramic piping, which require a stronger mating than plastic counterparts.
  2. The advantages of this sealant include its long service life and resistance to more than fifty chemically aggressive compounds.
  3. "Epoxy" is not resistant only to sulfuric and nitric acids, hydrogen peroxide, methyl ethyl ketone, acetone and fluorine compounds.

Hemp, jute rope

Another common sealant for water pipes made of metal and sewer analogs made of ceramics and cast iron is a jute or hemp rope, as well as a resin strand (kabolka). They are used to seal network sockets. I want to give you advice - the use of resin-impregnated rope is the preferred option.

Previously, only jute impregnated with resin was used to seal household communications. The principle of its operation is the same as that of self-adhesive tapes, but they are fixed in different ways.

Jute is an ordinary twine, tow. However, if it is impregnated with bitumen or resin, it is converted into a durable and strong sealant for sockets of ceramic and cast iron sewers.

Other funds

  1. Cement is a common element in some sealants. It is most often used for the manufacture of asbestos-cement mixtures and for caulking sewer sockets made of cast iron.
  2. Asphalt mastic and an analogue from petroleum bitumen are used for the production of casting compounds. They are needed to seal the joints and sockets of ceramic networks. For different types of pipelines, the following mastics are used: talc-bitumen, asbestos-polymer-bitumen, rubber-bitumen, polymer-bitumen, etc.

  1. Technical sulfur is used to seal the sockets of cast iron sewer pipes. Before using, it must be crushed, then heated until melted. It should be said that this method is now rarely used, because. sulfur has a very pungent and unpleasant odor.

Category No. 2: seals for the heating system

We all have to install a new heating network, change radiators and threaded joint seals shortly before the heating season. Find out from my article which sealants can now be used for this.

Linen tow

At the moment, there are many seals for radiators and pipes of heating systems that belong to different generations. One of the oldest sealants is linen tow, planted on paint.

However, this material was good many years ago, now it is of little use. I'll explain why:

  1. Flax is natural, i.e. degradable, hence short-lived sealant. Previously, cast-iron radiators were quietly operated for 40 years. However, now the conditions for the service of heating networks have become different. This sealant will have to be changed after 3-4 years.
  2. The current paints have a composition that is different from what the Soviet counterparts had. They are absolutely not suitable as impregnation of flax fibers. Silicone doesn't work for this either. It contains vinegar, which will corrode the threads.

  1. Modern high-rise buildings are not Khrushchevs with 2-5 floors. During pressure testing (testing pipelines for strength and tightness) and operation of the network of such a building, pressure up to 16 atmospheres is turned on. Linen sealant can be used at pressures up to 8 atmospheres.

As a result, the connections on the linen seal burst due to its swelling or cannot withstand the operating pressure in the heating system.

For apartments in a 1-5-storey apartment building, linen sealant can be used. There are only a few connections in the dwellings.
In your own house, cottage, the number of threaded mates on pipes can approach several hundred. It is highly undesirable to use linen sealant in them.

More modern means - polymer threads and anaerobic sealants

The photo shows the sealing of a pipe fitting with a polymer thread.

Linen, planted on paint, is gradually becoming a thing of the past. Now there is a more modern, reliable, safe and durable method of sealing pipes and elements of heating systems. It is based on the use of polymer threads and anaerobic gels.

  1. The anaerobic sealant for heating polymerizes in conjunction when in contact with metal, completely filling the entire thread. The connection will last as long as the pipes, without replacements and leaks. He will not be afraid high pressure and temperature, shock and vibration loads.
  2. Polymer threads are also an excellent sealant for threaded assemblies of heating systems. They are suitable for sealing metal, PVC and polypropylene pipes, whose conjugation is undesirable using gel materials. The operating temperature of the threads is not limited, and dismantling is easy.

In the table below, I present to you the technical characteristics of high-quality anaerobic gels from the Russian company PCT (Region Spetstechno).

Name purpose Characteristics

dimethacrylate polyglycol and modifiers. Fork operating temperatures -60/+150º.

Category No. 3: sealants for furnace equipment

Furnace equipment may crack due to temperature differences.

What are oven sealants for?

  1. Through cracks can reach the chimney. Then soot on its walls and increased fuel consumption will not be all problems. The living rooms will begin to penetrate harmful products burning.
    Chimney problems are not as common when made of quality ceramic or sandwich, but they are dangerous. For optimal traction, its channel must be sealed. This directly affects fire safety. Why?
  2. Soot often settles on the chimney walls. If it is not cleaned in a timely manner, it can catch fire with the access of air oxygen. The ignition temperature will be quite high - up to + 1500º. If the thermal insulation of the heated pipe is poor, then the ceilings or the roof will light up.
  3. Incomplete tightness of the chimney channel also leads to the fact that the fire of the gas burner goes out. This problem is widespread when using gas boilers.

To cover the cracks, as well as join the elements of the channel, it is best to use a pasty chimney sealant. The basis of such materials is different polymers that give different technical characteristics to the sealant.

They are packed in tubes of different configurations and volumes. There are packages that look like tubes of toothpaste. The sealant just squeezes out of them.

Tubes for mounting guns are also produced. In this case, on the cone of the lid, you need to cut off the spout, insert the sealant into the fixture and squeeze out the required amount of paste using the trigger lever.

Varieties of material

According to the release form, high-temperature seals are divided into two- and one-component.

The first of them must be mixed before use. In most cases, they are used by professional builders.
This is due to working conditions: when mixing components, you need to measure them very accurately. The maximum permissible error is only one gram.

In addition, with an accidental hit and a small proportion of the components into each other, the reaction begins, and the viability of the resulting mixture is only a few hours. Based on all this, for non-professional builders, I recommend using ready-to-use paste sealants.

Oven sealants are divided into two groups according to the area of ​​application and maintained temperatures.

  1. Heat-resistant seals are used for areas that are heated up to + 350º. The scope of their use: external surfaces of fireplaces and stoves, masonry joints (however, not between laying and casting the stove). They are also suitable for sealing joints between hot water and heating systems, sandwich chimneys and bricks with roofing.

  1. Heat-resistant and heat-resistant counterparts are able to resist to the limit high temperature- up to 1500º. The scope of their use in fireplaces and stoves is the interface between brickwork and furnace casting. In boilers, they are used in furnaces and combustion chambers. In chimney channels - at seams and mates, including those that go immediately after the outlet pipe.

These pastes can be used in direct contact with an open flame. However, then the sealant must have an additional characteristic on the packaging: “fire-resistant” or “fire-resistant”.

Heat resistant seals

This type of high temperature seals are silicone based. The temperature regime that the composition is able to withstand may vary, based on the exact composition of the paste. So, to increase the thermal resistance, silicone is modified with iron oxide.

Such a paste keeps the temperature well up to +250º, with a short increase to +315º. Iron oxide colors the sealant in a brownish-reddish tone.

Therefore, using a similar composition for a brick oven or fireplace, you will not spoil their appearance, it will not be visible. It can also be used to seal the joints of heating pipes. However, aesthetics suffer here.

Based on its composition, the silicone material can also be neutral or acidic. The latest analogues, drying, release vinegar. As a result, such seals must not be used for corrosion-resistant cements, concretes and metals.

In this case, a reaction occurs between the base and the seal, which leads to the appearance of a layer of oxides or salts, they destroy the tightness. Then the seams and joints cease to play their role, starting to let air and moisture through.

Cement, concrete and metal can be sealed with silicone-based neutral seals, as when cured, they release alcohol and water. The main properties of neutral heat-resistant sealants are below.

  1. UV resistant. As a result, they can be used outdoors, for example for sealing roof penetrations.
  2. Moisture resistance. This parameter makes it possible to use such a composition for chimney channels. For example, to seal the seams and cracks in the passages of the roof, at the junctions of its flooring, to seal the threaded joints when installing heating.
  3. Good adhesion to the base of different materials: concrete, brick, glass, metal, plastic, ceramics, wood.
  4. After hardening, the seal retains some elasticity, therefore it does not crack with slight vibration and deformation. However, plasticity also has its drawback - paint is not retained on silicone sealant. She peels and cracks.
  5. The drying period of the material can be equal to several hours and several days. This parameter is affected by the composition of the sealant and its storage time. The fresher the sealant, the faster it dries. The drying period is indicated on the packaging.

Manufacturers measure this parameter at a humidity level of 50 percent and a temperature of 23º. Changing their values ​​shortens or lengthens the drying time. The lower the humidity and temperature, the longer the sealant hardens.

The polymerization of the sealant starts from its surface and continues inward, it requires air moisture. Based on this, do not make the seams deeper than necessary, the silicone at the bottom simply may not harden. In this case, the joint or seam will let water or smoke through.

In order for the sealant to have a good adhesion to the base, I strongly advise you to prepare it.

  1. First, clean the surface to the very foundation: remove dirt, dust, salts and oxides.
  2. Then wash it with water and thoroughly degrease.
  3. Silicone-based seals must not be used on damp surfaces. Therefore, before sealing, wait until the base is completely dry.
  4. Silicone seal holds well on a smooth surface. However, to improve the grip, I recommend that you sandblast it, sandpaper it, or some other abrasive. Then wash the base again, wipe with a solvent and dry. Next, you can work with sealant.

All silicone-based oven materials are painted red or brown-reddish.

Heat-resistant analogues

Universal heat-resistant sealant is made on the basis of silicates. The operating temperature regime, which it withstands - up to +1300º, is able to endure short-term exposure to +1500º. This type of furnace sealant can be used in areas where there is direct contact with an open flame. In this case, the packaging of the sealant should be marked: "refractory".

Heat resistant seals are used:

  • for repair of leaks in heating boilers;
  • for sealing chimney pipes and sealing cracks in them;
  • for sealing areas of contact between brickwork and furnace casting;
  • for sealing fireclay masonry furnaces;
  • when installing a chimney from sandwiches, it is also highly desirable to coat their modular joints with a similar agent.

The exception is pyrolysis and condensing boilers, at the outlet their smoke temperature is up to +150º. Here you can use heat-resistant seals.

When it is planned to make a chimney channel or another element collapsible, apply sealant only at the joints. By loosening the two sections and crumbling the seal, you can separate them.
If you apply a layer of the agent to the entire surface, then the structure will become monolithic. You can't take it apart without damaging it.

Materials based on silicates have good adhesion to stone, brick, concrete, metal, cement mortar. However, I warn you that they are not firmly held on a smooth plane, as a result of which such surfaces require abrasive processing before applying the sealant.

I also want to note one point - it is possible to apply a sealant only at a range of positive temperatures: +5 / +40º. The best option is a temperature of at least + 20º, in which case the composition dries faster.

Once cured, the heat-resistant composition creates a strong and rigid, i.e. non-elastic seam. Based on this, silicate sealants can be used in areas that are not subject to vibration or are subject to it in small degree. Otherwise, the material will crack.

However, non-plasticity has its plus - it makes it possible to paint the sealant. The silicone composition is distributed using a mounting gun and a thickness of not more than one centimeter.

I ask you to pay special attention to the fact that some types of heat-resistant sealants, once on the skin, can cause chemical burns. Based on this, when working with your own hands, wear rubber gloves on them and be careful.

Fire-resistant and heat-resistant oven sealants are painted in black or gray. They don't have any other colors..

  1. They are not pure sealants, but a sealing adhesive.
  2. These funds are transparent, they can withstand extreme temperatures up to + 200º.
  3. Such compositions are chemically neutral, i.e. they do not react with salts and acids. The period of their drying is not affected by humidity and temperature. Thanks to this, they can be used outdoors and in the winter season.
  4. Sealing adhesives are waterproof. Therefore, they can be used in rooms with a high level of humidity - in the shower, bath, bath, etc.
  5. The relative disadvantage of such compositions is that they are not high-temperature.

Of these seals, I can recommend Soudal's "Fix All" sealing adhesive. It does not directly relate to heat-resistant counterparts, but it is perfect for repairing leaks, cracks in heating networks, as well as hot water supply, both in the pipes themselves and in fittings.

Popular brands of funds

Almost always, manufacturing companies write on the packaging of heat-resistant sealants their main purpose. For example: "sealer for chimneys, fireplaces and stoves." So, with a choice you will not be mistaken.

  1. Soudal-C. The Belgian company Saudal manufactures a diverse range of sealing materials. Among them are heat-resistant analogues, there are also heat-resistant stove, fireplace seals "Soudal-Calofer". Such compositions are painted in black.
  1. Penosil manufactures Penosil/+1500, a heat resistant oven sealant. It is black in color and can withstand temperatures up to +1500º. It polymerizes within 15 minutes.
    The company also has heat-resistant analogues of red color, holding temperatures up to + 300º. They are acidic, so they cannot be used for concrete, cement and metal.
  2. In the middle price segment, you can also find seals that have good quality. For example, heat-resistant sealants of the Tytan and Bau-Master brands.

Under the Titan brand, Selena-Group, a group of companies from Poland, produces professional-grade building and finishing materials, including oven sealants. They are standardized and certified by DIN and ISO No. 9001.

Tytan high temperature seal is modified with fiberglass, it informs the material a high degree gas and smoke tightness. It is able to withstand temperatures up to +1250º. This composition is suitable for chimneys and stoves.

Conclusion

Without pipe sealants, the effective operation of many engineering networks is impossible. Depending on the type of network, different types of seals should be used.

Elements that heat pipelines are expensive. But this does not prevent them from being very popular. These elements are able to warn when the pipes will be defrosted. Of course, if they are applied, the cost will be less than changing pipelines later. Basically, these elements will automatically respond to temperature, which is very convenient.
The main elements for are cable and tape.
As a rule, a heating tape or cable is used to heat pipelines that are intended for cold or hot water disposal and water supply. Of course, pipelines that are designed to supply hot water will not freeze. However, heating tape should also be used to avoid heat loss. It will perfectly prevent heat loss.
If we talk about cold water supply, then this tape gives an excellent effect. The heating system will make the line at a shallower depth. This will save a lot of money, as the earthwork will be much less, and the tapes will make it possible to secure the pipes.

Market Review


Insulating tape for water supply and heating pipes

Tape systems are of different types. They will differ in the technology by which it is made and technical specifications. Let's look at what tapes are.

stranded

Pipe Sealing Tape

This tape is made of fiberglass. A large amount of wire is fixed on it, which is made of a material with high resistance. Usually use nichrome made with organosilicate composite. This type will be supplied with low-temperature outputs. This is necessary to connect the power supply.
Atel heating nye tapes are made by high-tech methods, so they have a certain length. Also, a thermostat will need to be installed through the system, which will monitor the temperature of the cable so that the pipes do not overheat.

This pipeline heating system is made of copper conductors. They are installed in parallel. Between them there is a special material that must change its resistance. From what the temperature will be, the resistance will also change. This is located on the outer armor shell.
The main advantage is that for heating pipelines it is not necessary to install special temperature sensors and temperature control devices. The self-regulating cable will judge the temperature itself.
These tapes are quite simple. They are sold by the meter or in reels. Connect to the network using simple control devices.
Helpful advice. To install the heating tape in a spiral way, overlapping edges must not be allowed. This is dangerous because it can lead to overheating.

Infrared film

This material is quite new, of high quality and very promising. The infrared tape for pipelines consists of a conductive polymer film, and it in turn consists of a carbon composition with the copper wire method discussed above. The heating effect is based on the fact that infrared radiation is transmitted directly to the heating cable.
For infrared tape, additional thermostats and temperature sensors are needed. They also need to be covered with an additional layer of thermal insulation.


Required power

To calculate the required power of the heating tape for pipes, and in what quantity it is needed, it will be necessary to take into account some factors:
Pipeline diameter.
The depth to which you plan to lay.
It is necessary to calculate the temperature difference between the pipe wall and the external environment.
The length of the pipeline to be heated.
Type of seal and installation method


PVC Pipe Tape

Working mode

Helpful advice. If you increase the layer of the tape, then it will be possible to strengthen the protection of the pipe from mechanical pressure. You will be able to buy them in good quantities, but less power. Over time, you can save on electricity with these tapes.

Heat-shrinkable tape for heating pipes

You will also need to take into account the operating mode of the heater:
1. Continuous heater will be able to maintain required temperature in the pipe. Usually this mode is used for hot water pipelines.
2. Periodic mode - from time to time allows the pipes to cool down to ambient temperature or drops to the desired value, which is set in advance.
The required amount of material can be calculated using special formulas established by manufacturers.

Installation instructions


Adhesive tapes (adhesive tapes)

Installing a pipe heating system is quite simple. The desired cable must be pressed against the pipe and fixed with aluminum tape (see). It also provides additional thermal insulation.
When installing the tape, you need to carefully treat it. It is sensitive to damage, and the cable must not be allowed to cross or overlap, so that this does not lead to breakage. This applies to heating cables.

Self-adjusting tape is not as sensitive. It is more difficult to break it, since it is not very afraid of crossing and overlapping.
As soon as it is installed, you need to immediately take care of a layer of additional thermal insulation and, in some cases, you need to install a waterproofing layer. Thermal sensors should be installed in the main sections of the water supply. Installing them is simple, you just need to fix them with adhesive tape on the pipe.
When installing in winter, you need to remember that the systems will become rigid and flat. But in this case, you can connect the cable to the network. The system will warm up a little and become more flexible, which will allow you to continue installation.
As a rule, the pipe heating element can be separately installed inside the pipe. So installation will become more difficult, but the efficiency of this device will become greater.
Such a system will allow you to spend less electrical energy. At internal system cable heating, you will heat the liquid, not the walls of the pipe.
The technology by which pipelines are heated has been used recently. Although, heating cables are already considered obsolete. But tape is the material of the future, as many experts say. And, however, it is very promising, since many of its variations have already appeared and it is quite reliable and durable.
