In many pipe materials, the coefficient of friction of UHMWPE is minimum, especially since the ultrahigh molecular chain is long, the wear resistance of UHMWPE is 4 -7 times than steel and stainless steel when when conveying various slurry, and about 10 times higher than PVC pipe and polyethylene pipe, it greatly improve the life of the pipeline.
wear rate of UHMWPE pipe is 21 (pipe is 100), which is five times the wear resistance of the steel pipe, steel lined ultrahigh molecular weight polyethylene pipe (1.0MPa or more working pressure use composite pipe , 1.0MPa or less use single-walled pipe) combines the advantages of the ultra high molecular weight polyethylene and overcomes the shortcomings of low pressure.
Under the same operating conditions, UHMWPE pipe's life is 4-6 times of steel, greatly reduces the cost for the use unit. Based on the use of an iron and steel group:. Steel pipe, whose working pressure is 3.0MPa, the life is generally about one year, but the lined ultra high molecular weight polyethylene pipe's life is about three years, it shows that its cost is 25-30% of steel pipe.
