Sewage asbestos cement pipeline depressurized

Sewage concrete free-flow pipeline

In fact, pipes made of asbestos does not concede to its metal counterparts strength.They are resistant to various chemical influences, low temperatures and corrosion.Their installation is easy and simple, plus everything, asbestos cement non-pressure pipes have good thermal insulation properties.A particular advantage is its price, which is very accessible.According to GOST defining various, non-pressure pipes such diameter may be ranging from 100 to 500 millimeters.

They are used as drains and sinks in the non-pressure sewer systems.In addition, pipes made of asbestos used for laying telecommunication cables, chimneys, electrical wires and chutes.Also, builders are often used as fence structures, cellars and other structures.

Compare RC pipes with other

Another alternative installing sewage non-pressure pipe, can be mounting the RC pipes.They are placed at a certain depth below ground, where they can carry out transportation:

• atmospheric waste waters;
• groundwater;
• household liquids, non-corrosive to concrete and rubber, which acts as a seal;
• industrial fluids.

They are made of heavy concrete using vibrogidropressovaniya technology.If the comparison with analogues, the RC pipes have increased strength.They are characterized by high crack resistance, frost resistance and water resistance.

inner surface of the bell-mouthed non-pressure pipe is processed by grinding, so they are technologically advanced and are easy to install, and have almost complete integrity.

RC pipes are divided into three categories (the distance to the top of the pipe), relative strength:

• to 6 meters;
• to 4 meters;
• up to 2 meters;

bearing capacity increases due to reinforcement, and the thickness of the wall is the same for the same diameter.

Polymeric materials as sewage non-pressure pipes

PVC pipes are used almost everywhere and are renowned due to its following performance properties:

1. resistant to chemicals;
2. not corrode;
3. Characterized by long service life;
4. easy to install;
5. easily transported.
6. relatively small cost.

Thus, they occupy an important place in the construction market.In the utilities sector, such tubes are used in large quantities for construction and other requirements.Speaking objectively, the pipes of a polymer can be considered as the basis of house sewage networks.They are mounted in the socket, with no special equipment is required.At one end of the pipeline there is the funnel through which the ends are joined.

Non-pressure PVC pipes are divided into two types:

• Sandwich;
• Monolithic.

Depending on the hardness, they are classified into the following classes:

• SN2 - set to a depth of 1 m;
• SN4 - up to 6m;
• SN8 - up to 8m;
• SN16 - do16m.

By type, the polymer tube can be divided into:

• Corrugated - designed for drainage.
• Spiral - used for the organization of technical and livnevki sewer system.
