With the improvement of people's living standards, environmental protection awareness and health concerns, a green revolution in the building materials industry has been set off in the field of water supply and drainage. According to a large number of water quality monitoring data, cold-galvanized steel pipes generally rust after less than 5 years of service life, and the iron smell is serious. Residents complained to government departments one after another, causing a kind of social problem. Compared with traditional metal pipes, plastic pipes have the characteristics of light weight, corrosion resistance, high compressive strength, sanitation and safety, low water flow resistance, energy saving, metal saving, improved living environment, long service life, and convenient installation. Favored by the engineering community and occupies a very important position, forming an unreasonable development trend.
Plastic pipes are generally made of synthetic resin, that is, polyester as raw material, added with stabilizers, lubricants, plasticizers, etc., and are extruded in a pipe making machine by a "plastic" method. Mainly used for tap water supply system piping, drainage, exhaust and sewage sanitation pipes, underground drainage pipe systems, rainwater pipes and threading pipes for wire installation in housing construction.
Plastic pipes are divided into two categories: thermoplastic pipes and thermosetting plastic pipes. Thermoplastics include polyvinyl chloride pipes, polyethylene pipes, polypropylene pipes, polyoxymethylene pipes, etc.; thermosets include phenol plastic pipes, etc.
Plastic pipes are generally made of synthetic resin, that is, polyester as raw material, added with stabilizers, lubricants, plasticizers, etc., and are extruded in a pipe making machine by a "plastic" method. Because it has the characteristics of light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing, convenient construction, etc.,
It has been widely used in construction engineering. Mainly used for tap water supply system piping, drainage, exhaust and sewage sanitation pipes, underground drainage pipe systems, rainwater pipes and threading pipes for wire installation in housing construction.
