The process of sealing pipes is strategically important, ensuring an impeccable and reliable operation in the future. Modern materials for sealing do not look like their ancestors at all - linseed, a band with impregnation and oil paint. What are the current materials for pipe sealing?

Main characteristics of sealants
High technologies of the construction industry always make special demands on materials. This applies fully to sealants, especially since they are widely used for a wide range of repair and installation works. The sealant is a special composition made of polymers.
Characteristics of sealants are the basis of their properties:
• strength and resistance to deformation
• resistance to moisture
• Retention of elasticity during shrinkage and curing.
With the help of sealants, cracks and seams are filled, and pipes are sealed. What are these pasty materials?
Types of sealants
Depending on the base material, the following types of sealant are distinguished:
• Acrylic
• silicone
• Bituminous
• sealing tapes
• grease
There are sealants for indoor and outdoor work.
The place of application of the sealant can be various:
• universal for gluing any surfaces
• for sealing cracks in batteries (heat-resistant)
• roof sealant
• for pipes (threaded)

Silicone sealant
The most demanded material for sealing pipes is silicone. This type of sealant has considerable strength to the effects of climate change, chemicals and sunlight. Can be used for outdoor and indoor work. Silicone sealant shows adhesion to non-porous materials: plastic, tile, enamel or surfaces coated with a layer of paint.
Therefore, it is used to eliminate leaks in the kitchen, bathroom, dachas. Silicone sealant is the guarantee of elastic and long-term sealing of pipes. What is the reason for this qualitative sealing?
The basis of silicone sealants is synthetic rubber. Before applying the sealant from silicone, no preliminary surface treatment with primers is required. Depending on the type of hardener, the sealant for sewer pipes is divided into:
• neutral
• Acidic.
Neutral sealants are considered the most versatile.
The neutral sealant emits ketoxime during vulcanization. After the vulcanization process, upon curing, the ketoxime is converted into a thin film with a slight shrinkage. The strength characteristics of such a film exceed the performance of all existing sealants. However, it should be remembered that for metallic surfaces such a sealant can not be used.
Acid sealants are characterized by the possibility of interaction with a certain type of surface. Therefore, when choosing the acid, it is necessary to specify the type of the working surface and to guess which sealant to choose.
With the help of silicone sealants it is possible to seal the joints of sewer pipes from the following materials:
• plastic
• metal.
Transparent silicone sealants are made of silicone polymer - acetoxy and belong to the acid type. Silicone sealants are universal and sanitary grade. Sanitary silicone used for plumbing, as well as for the repair of bathtubs and showers. The sealant is applied at a temperature of +5 to + 40 degrees. In the process of operation, it does not lose its positive qualities even at negative temperatures. The most famous manufacturers of silicone sealant are brands:
• The Moment of Henkel
• Ceresit
• "Macrosil"
• Penosil
At the end of the vulcanization process, the silicone paste is converted into a substance similar in its properties and properties to rubber during the chemical reaction. The catalyst of the vulcanization process of silicone sealant is moisture in the air.
In addition to silicone sealants, sealing tapes are used throughout the sealing of pipes.
Sealing tapes
Tapes for sealing are manufactured by the industry in the form of self-adhesive tapes. Perhaps simple and foil-made waterproofing tape with protection from natural copper. The composition of the sealing tape includes bitumen-polymer materials. Self-adhesive tape is the know-how of modern sealing means.
Suffice it to recall that sealing films, due to the synthetic high-strength basis of polyethylene, have excellent performance. In support of this, try to break off the tape with your hands for sealing, you are unlikely to get it. Among other things, sealing tapes have the following properties:
• anti-corrosion
• Dielectric.
Sealing pipes with the use of tape is possible when sealing the joints of sewer pipes, plugs, turning corners, taps and notches, not to mention the linear sections and elements. When sealing pipes using a tape, a working surface is prepared. The tape is superimposed in a spiral with tension, providing an overlap. The insulated surface will thus be under the sealing layers.
Sealing tapes are very popular:
• Bande Adealu
• Ecobit (Ekobit)
• Butylene.
Sealing lubricants and threads
The need to fill the thread gap, eliminating the slightest leakage, fully provide beneficial and practical hermetic greases. The help of sealing lubricants is indispensable when it is necessary to ensure a high density of the threaded joint on the pipes. Therefore, of the majority of modern sealants, lubricants are most in demand. What are the exclusive properties of sealing lubricants?
Hermetic greases of one-component content, having an anaerobic structure, differ the following qualities:
• increased flexibility of lubricating properties
• sealing of threaded parts and incisions with minimal effort.
With the use of sealing lubricants, it is possible to seal the pipes even in conditions of increased pressure. You just spread the grease and that's it!
Sealing threads are a ready-to-use sealing fiber.
The sealing fiber is wound directly onto the turns of the pipeline fittings. A convenient plastic dispensing container is a storage of threads and a distributor. Sealing threads are designed for sealing pipes with conical and cylindrical threads. The sealant does not require full curing and instantly performs sealing.
