Ultra-High Molecular Weight Polyethylene (UHMWPE) pipes are made of ultra-high molecular weight polyethylene raw materials with a viscosity average molecular weight of 3.5 million to 9.2 million. They are extruded under high temperature and high pressure by special machinery. Is an extremely tough plastic with high wear and abrasion resistance.
They are widely used in mining, electric power, coal, chemical industry and other special mining enterprises, blow filling, dredging, and mine tailings. Mine, ash and slag transportation and other fields. is ideal for slurry pipe and dredging pipe.
» 40 times the abrasion resistance of steel
» 8 times lighter than steel
» 5 times lower coefficient offriction than steel
» The pressure loss of UHMWPE pipe is 1/10 of steel pipes
» impact resistant which is 5 times that of HDPE pipe
» compressive strength is 2 times to that of PE100 pipe
» friction resistance is 0.009, Improves transmission efficiency by over 20%
» still work on temperature of -70 ℃
» elongation of no less than 350%
