Plastic sewage gradually replaces outdated solutions from cast iron, concrete and steel. In this sewage, substances such as polyvinyl chloride, polyethylene, polypropylene are used for the manufacture of pipes. The main advantages of plastic pipes include the following features:- small weight of the structure;- lightness in installation and movement;- good resistance to aggressive chemical compounds;- non-misconduct of corrosion;- smooth surface (as a result- lack of deposits on the walls); – safety for humans and the environment;- high-quality isolation;- durability.
Plastic pipes can be laid at a short distance from power lines – they are reliably protected from current exposure. You can lay them as simple and convenient for you, they do not need constant care (for example, regular painting). With a long service life (and this is about 50 years), they cost much cheaper than steel and cast -iron analogues. The disadvantages of plastic pipes include low frost resistance, low operating temperature (overheated boiling water cannot be allowed through them).
