HDPE Pipe HDPE Pipe is made from high density polyethylene resin, belongs to flexible plastic pipes. HDPE pipes have good rigidity and toughness, excellent corrosion resistance and the high impermeability and strong molecular bond help it to have high mechanical strength to bear high pressure. HDPE Pipe is made from high density polyethylene resin, belongs to flexible plastic pipes. HDPE pipes have good rigidity and toughness, excellent corrosion resistance and the high impermeability and strong molecular bond help it to have high mechanical strength to bear high pressure. HDPE pipes are usually used for fluid transmission, such as, water, slurry, rurual irrigation, sea water and drainage, etc. Furthermore, HDPE pipes have wide application to work as gas lines, electrical and comminication conduit, etc.
