Ultra High Molecular Weight Polyethylene(UHMWPE for short)pipe was extruded out with 1.5~9.2 million viscosity-average molecular weight material by extruding machine in high temperature and pressure situation. The UHMWPE pipeline is widely applied in the fields of hydraulic reclamation,dredging, mine tailing,ash transporting and so on.
