Sound insulation of sewage pipes

Causes of noise

1. The pipe wall width - the most noisy are the pipelines with a small wall thickness
2. The building material from which the communications are made - polymer pipes practically do not absorb noise, which can not be said about cast-iron ones.
3. Placing pipes against walls - the most profitable is the design of sewerage separately from residential premises in special mines.
4. Material used for insulation - application of a mounting foam that conducts sound well is not recommended.

Types of sound insulation of pipes

• Use of pipes of special design. In today's market there are high-tech products made of polymer enriched with mineral materials, which has a high density, and as a result they have a high sound absorption capacity.
• Application of special insulation. Sound insulation of sewer pipes is carried out by wrapping special materials around the pipelines, duly insulating the pipes, and also used as a thermal insulation.

Types of insulating materials

1. The use of foamed PE as not only sound-absorbing, but also heat-insulating material is very effective in view of its high porosity. Also, it does not allow moisture to condense on the surface of the pipes, which prevents the appearance of mold and fungus.
   

   . It is necessary to choose insulation, the outer film of which is highly durable, which will allow it to be used for a long time.

2. A special insulating tape with a soundproofing effect is wound onto the pipeline in several layers, withstanding its closest contact with the surface.
   

   The effectiveness of a particular type of tape depends on its isolation capabilities, which can be recognized from the markings printed on the packaging.

3. Roll-up soundproofing is a bit old-fashioned and is carried out by winding around the pipe and fastening with ties or wire

To increase noise insulation, it is necessary to achieve maximum contact of the material with the surface without forming an air layer.

Insulation of external drainage system

Various materials are used for insulation of external drainage systems, the following are most often used:

• Mineral or glass wool with sheets of large pipes
• Pipe sleeves that are worn on communications, after which they are glued
• Foam shell, which is installedon pipes and fixed due to the design features of the

Building materials used as insulation, most often are foamedny polyethylene, basalt and glass fiber sheets, generally used for neuglublennyh sewer networks, mineral wool, withstanding high temperatures up to 750 degrees, as well as rubber, at which the maximum isolation is achieved by sealing.

Sound insulation of sewer pipes, along with thermal insulation, is an extremely important part of the installation, repair and finishing of the network, must be performed at a high level. The efficiency and longevity of the system depend on the quality of the insulation.
