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. UHMWPE engineering plastics pipe technology has matured gradually in China, more and more projects start to use this kind of wear-resistant material, and it becomes a new engineering thermoplastics with moderate price and excellent performance. It can be widely used in mining, mineral powder, pulp, tailings discharge pipeline), metallurgy, electric power, petroleum, textile, papermaking, food, chemical, mechanical, electrical and other industries.
