Selection of pipes for outdoor Sewerage

For convenience and normal life, you need to ensure your home utilities, including sewer. For private homes wiring external piping is no less important than the construction of internal networks, because it will transport the sewage to the collector. To install such a pipeline uses pipes for outer sewage systems. Manufacturers offer a wide enough selection, however, not to be mistaken in it, you need to know some requirements for pipes and take into account the peculiarities of their operation.

Key selection criteria

Selecting pipe, be aware that they will be subjected to soil pressure and other negative influences.

Therefore, the main criteria in the selection of these tubes must be:

• strength – the capability to cope with the serious stress;
• reliability because repairs on the pipeline of sewage is quite difficult;
• durability – because they are more often subjected to external impacts.
• frost – because they are less protected from the influence of temperature.

Material

For the outdoor sewer pipes used cast iron, concrete, ceramic and asbestos cement. However, in the process of operation of each of these materials has shown far not the best quality. For example, cast iron pipe is too heavy, and therefore require the use of special equipment during installation. The same applies to pipes made of reinforced concrete.

Asbestos is a winning plan, but require compliance with special caution in transportation and installation due to increased brittleness.

Ceramic is also quite fragile material. In addition, these pipes have a length limit, but because the big length of the pipeline have to do a lot of joints, which greatly reduces the reliability index.

Pipes of these materials are becoming increasingly rare. They are replaced by pipes made of polymer materials: PVC, polyethylene and polypropylene. Also used, though less frequently, metal products.

Corrugated pipe

Of all the varieties of the plastic pipes most successful option is a corrugated pipe. She has such design which significantly improves its quality, especially durability.

This double-layered pipe in which the outer surface is equipped with a large number of stiffeners. They make the product capable of withstanding significant loads from the ground and from the movement of cars and people. As for the inner surface, it is made very smooth, to waste water moving through it with the least resistance.

The correct selection of the outer pipes will provide them with reliable and long service, the ability to withstand various loads, durability and wear resistance.
