Hdpe Drainage Pipe Manufacturer in China
‌HDPE drainage pipe is a thermoplastic drainage pipe made of high-density polyethylene resin as the main raw material through extrusion molding process. Its molecular chain is linearly and tightly arranged, with a crystallinity of 80% – 90% and a density between 0.941 – 0.965g/cm³, giving the pipe high strength, wear resistance and excellent chemical stability.
In terms of performance, HDPE drainage pipe has outstanding corrosion resistance, can resist erosion by various chemical media such as acid, alkali, and salt, and does not react with microorganisms in domestic sewage and industrial wastewater, with a service life of up to 50 years
