Today, the installation process of external sewer pipes is carried out using special smooth pipes made from PVC (meaning polyvinyl chloride). A characteristic distinctive feature of all these pipes is that almost all of them have a fairly bright orange outer surface.
In the process of installation, it is necessary to take into account the fact that with increased load on the laid sewer pipes, it is best to use pipes with the so -called enlarged rigidity or special corrugated bilateral pipes, which, as a rule, include polyethylene. Most often, such a need arises provided that the sewer pipes will allegedly pass under the carriageway or will be designed for a very deep falling.
Absolutely all sewer pipes can be divided into three main categories today. Namely for pipes:
? external sewage system;
? internal sewage system;
? Mistine elements of pipelines.
In accordance with this, each of the above pipes needs certain installation works and specific conditions that must be complied with. This applies to an external sewer pipes, since due to certain circumstances (and, in particular, with improper installation), they can be subject to corrosion and various destructive processes.
