Pipe for outdoor sewage: features

The pipe for outdoor sewerage is currently most often made of PVC. This material has proven itself quite well in many industries. It greatly facilitates the weight of the product, which positively affects the convenience during transportation and packing. Absolute resistance of PVC pipes to corrosion is also an important factor.

Pipe for outdoor sewage from PVC can be considered the optimal solution, since in this case there is a better "price-quality" ratio. Such pipelines are able to form a single system with the surrounding ground, which can absorb loads, has the property of self-cleaning, and the expansion coefficient in this case is very low. The external sewerage is subjected to a much greater load than to the internal one, so the pipes for it must be made of a polymer having a high strength. The walls of such pipes are made homogeneous if the diameter is 110-200 millimeters, and three-layered, if the diameter is 250-500 millimeters. In the second case, the middle layer is made of foam material.

The pipe for external sewage can be made from asbestos-cement, cast iron, polyethylene. The first type has such advantages as cheapness and reliability, but it is quite fragile, which is why there may be problems in transportation. Polypropylene pipes can last more than half a century.

You can consider what kind of sewage pipes for outdoor sewage. Asbestos-cement is produced from asbestos fiber and Portland cement. Their weight is small enough, the strength is high, they remain smooth for a long time, so that the throughput remains . Mounting them is very easy.

A pipe for external sewerage ceramic is not used very often. However, in terms of performance, it is capable of even surpassing the cast iron. Such pipes are durable, well maintain the smoothness of the internal surface, are not affected by corrosive processes. A short length and fragility are their main shortcomings. A significant number of joints is unacceptable for long pipelines.

A classic option is cast-iron pipes. They are very reliable, have good mechanical and chemical strength. In the process of their installation, bell joints are used, which can guarantee reliable contact in the conditions of correct sealing. The big weight - here the most significant lack of such pipes, essentially complicating process of their installation. If it is a matter of laying a large- diameter system , then it can not be handled without the use of special lifting equipment.

PVC pipes for outdoor sewage are most often used. This option has a lot of advantages:

• Relatively low cost;
• Simplicity of installation;
• Chemical resistance;
• durability.

All these qualities and made this option the most suitable for various purposes.
