If we talk about sewage, then all of it can be divided into two types: cast -iron and plastic. It is customary to use cast-iron sewage in the construction of large buildings: business centers, supermarkets, high-rise buildings of various purposes. It is also customary to use cast -iron sewers when laying various communications at construction facilities, which are presented by special requirements regarding sound insulation and fire safety.
It has long been known that a breakthrough of communications in the building can create big problems, such situations are especially unpleasant if the buildings have several floors and they are located in a modern metropolis. Dozens, and sometimes hundreds of people will be placed in terrible conditions if an accident occurs. Such situations can be excluded if you use the pipe from cast iron when laying. Such pipes are simply indispensable in structures, the load of which goes beyond household. Such buildings include catering and food industries, meat processing plants, farms and other other places where animals are contained. You can not do without such cast -iron sewage in the sanatorium, especially if they have a mineral or thermal water yield, in health and education facilities.
Modern cast -iron sewage is made from very durable cast iron using the newest technologies. Such pipes are easily processed and cut, they are durable, durable, fireproof, heat resistant and tight. The disadvantages include great weight, laborious installation and some others.
Plastic sewage can be made of polyvinyl chloride, non -plasticized polyvinyl chloride and polypropylene. Polyvinyl chloride is excellent material for modern sewer systems. These pipes retain their properties even after many years of operation. They have increased mechanical strength and resistance to heat, but at the same time, at low temperatures, they become fragile, which in the conditions of Russian winter is not the most attractive quality. Unplastified polyvinyl chloride is best suited for the water supply of household, pressure or non-pressure sewer and so on. .
