Plastic pipes are generally made of synthetic resin, that is, polyester, with stabilizers, lubricants, plasticizers, etc., and are extruded in a pipe making machine by the "plastic" method. Due to its light weight, corrosion resistance, beautiful appearance, no bad odor, easy processing, and convenient construction, it has been increasingly widely used in construction projects. It is mainly used as piping for tap water supply systems in housing buildings, drainage, exhaust and sewage sanitary pipes, underground drainage pipe systems, rainwater pipes, and threading pipes for wire installation.
