Without a high-quality sewerage system, it is simply unrealistic to provide an adequate level of comfort for a modern home. But if you save on building it, you provide yourself with a whole litter of problems, so all the elements of the drainage system must be of the best quality.
External sewer pipes should be chosen especially carefully. Fortunately, modern industry can offer a huge amount of quality and durable materials, so this is not so difficult.
In large drain systems, pipes made of asbestos cement, reinforced concrete, cast iron or polymeric materials can be used. However, recently pipes made of asbestos cement or cast iron have not actually been found, since their cost is somewhat inconsistent with performance. In addition, the recently ubiquitous polymer outdoor sewer pipes are much easier to maintain and install.
In particular, having been so popular relatively recently, metal pipes have a bunch of seriousshortcomings. The most obvious is poor corrosion resistance. It is believed that in just one year a standard steel pipe becomes thinner by at least one millimeter. If we take into account the harsh action of stray currents and the possible features of the soil, then in some areas the service life of such materials does not exceed five to six years. Such a sewer (external) pipe is not only expensive, but also does not justify its high price.
And therefore, when choosing the most suitable material, several important parameters should be taken into account at once:
- strength characteristics;
- durability;
- ability to endure exposure to aggressive chemical environments;
- resistant to temperature extremes.
Consider those outdoor sewer pipes that best meet all of the above requirements.
Asbestos-cement varieties
These lightweight and durable pipes are made from asbestos and Portland cement. Given the smoothness of their inner surface, they do not get clogged too often. Unfortunately, their significant drawback is their somewhat increased fragility, and therefore it is necessary to work with such pipes as carefully as possible.
Polymer Models
These outdoor sewer pipes have been the most used lately. They are very durable, light in weight, easy to mount and almost indestructible.blockages. The disadvantage is that for their correct installation it is often necessary to use special welded machines, which require the presence of electricity at the facility being built. However, given their low price and high performance, these "roughness" can be easily reconciled.
Cast iron pipes
No matter how good polymer materials are, their mechanical strength and resistance to elevated temperatures leave much to be desired. Cast iron, on the other hand, is distinguished by high reliability and longevity, as well as good resistance to aggressive chemical environments. Its disadvantage is the weight, as well as the complexity of the connection.
Thus, outdoor sewer pipes (the price of which depends on their type and manufacturer) must be chosen wisely, focusing on your needs.
