Whether it is the construction of urban construction in modern or ancient society, there will always be the problem of sewage discharge. If the sewage treatment is not done well, it will have a great impact on the future life. The commonly used types of sewage pipes are, plastic pipes and their pipe fittings, rigid polyvinyl chloride pipes (UPVC), rigid polyvinyl chloride pipes are the most widely used plastic pipes at home and abroad, which has excellent impact resistance and chemical resistance.

Rigid polyvinyl chloride pipe (UPVC) is essentially a plastic pipe, and the interface is generally bonded with glue, and the heat resistance and frost resistance of UPVC pipe are not very good. Therefore, it is rarely used as hot and cold water pipes, PVC pipes are suitable for sewage pipes and wire pipes. In fact, it is a kind of plastic pipe, and the interface is generally glued together, and the frost resistance and heat resistance of UPVC pipe are not good. Therefore, hot and cold water pipes are rarely used, PVC pipes are suitable for wire pipes and sewage pipes.

PP spiral wound pipe is a plastic pipe using winding molding process, which has the advantages of light weight, strong stiffness, high flexibility, low temperature resistance and corrosion resistance, which can effectively make up for the shortcomings of three traditional materials, and can be widely used in urban drainage, sewage and industrial water transportation and other fields.

It is understood that the pipelines traditionally used in urban drainage and sewage systems mostly use cement, PE (polyethylene), glass fiber reinforced plastic and other materials, but there are problems such as poor rigidity, poor connection, easy leakage, and easy collapse. If you want to solve the problem of urban drainage and sewage discharge, you can't completely solve it by relying on three traditional materials.
