Select outdoor sewer pipes

Without a quality sewer system, to provide the proper level of comfort for a modern home is simply unrealistic. But if you save on its construction, then provide yourself with a whole brood of problems, so that all elements of the drain system should be of better quality.

Especially carefully you should choose external sewer pipes. Fortunately, modern industry can offer a huge amount of high-quality and durable materials, so this is not so difficult.

In large drainage systems, pipes made of asbestos cement, reinforced concrete, cast iron or polymeric materials can be used. However, in recent years, pipes from asbestos-cement or cast iron have not actually been found, since their value does not correlate with operational qualities. In addition, ubiquitous polymer outdoor sewer pipes are much easier to maintain and install.

In particular, formerly so popular relatively recently, metal pipes have a lot of serious flaws. The most obvious is the poor resistance to corrosion. It is believed that in just one year the standard steel pipe is thinned by at least one millimeter. If we take into account the stiff action of wandering currents and possible features of the soil, in some areas the service life of such materials does not exceed five to six years. This sewer pipe (external) is not only expensive, but also does not justify its high price.

Therefore, when choosing the most suitable material, several important parameters should be taken into account at once:

• Strength characteristics;
• Durability;
• Ability to withstand the impact of aggressive chemical media;
• Resistance to temperature changes.

Let's consider those external sewer pipes, which in a greater degree meet all the above requirements.

Asbestos-cement varieties

These light and durable pipes are made from asbestos and Portland cement. Given the smoothness of their inner surface, they are not clogged too often. Unfortunately, their considerable disadvantage is somewhat increased fragility, and therefore it is necessary to work with such pipes as accurately as possible.

Polymer Models

These outdoor sewer pipes have recently been used most often. They are very durable, light in weight, easy to assemble and almost unaffected by blockages. The disadvantage is that for their correct installation, it is often necessary to use special welded machines that require the presence of electric power at the object being erected. However, given their low price and high performance, these "roughness" can easily be reconciled.

Cast-iron pipes

No matter how good the polymer materials, but their mechanical strength and resistance to high temperatures leave much to be desired. Cast iron is distinguished by high reliability and longevity, as well as good resistance to the influence of aggressive chemical media. Its lack of weight, as well as the complexity of the connection.

Thus, external sewage pipes (the price of which depends on their type and manufacturer) must be chosen with intelligence, focusing on their needs.
