Characteristics of UHMW PE engineering plastics pipes

UHMW-PE pipes are suitable for water quality fluids, solid particles, powders, slurries, etc. traditional metal pipes are difficult to meet the requirements. UHMW-PE pipes can be replaced with high corrosion resistance, high wear resistance, self-lubricating absorption impact and other comprehensive properties, which are widely used in various industries. UHMW-PE pipes are widely used in solid particles, powders Slurry and gas transportation.

According to the Research Report on the abrasion test of plastic pipes issued by Beijing Nonferrous Metallurgy Design and Research Institute, the following four pipes of different materials are tested under the same pipe diameter, flow rate, test materials and concentration. The results are as follows: the average annual abrasion thickness of glass fiber reinforced polypropylene pipe is 11.5424mm/year; the engineering grade polypropylene pipe (PP) is 13.5828mm/year; the ultra high molecular weight polyethylene pipe (UHMW) is 13.5828mm/year--- PE) 5.0104mm/year; steel pipe (A3) 36.24244mm/year; the test results show that the wear resistance of UHMW-PE pipe is seven times of that of steel pipe (A3).

The unique molecular structure of ultra-high molecular weight polyethylene pipe has extremely high anti sliding friction and light weight advantages. The proportion of unit pipe length is only 1/8 of the weight of the steel pipe, which makes handling, transportation and installation more convenient, and can reduce the labor intensity of workers. UHMW-PE pipeline has very strong anti-aging properties, and it is not easy to be aged for 50 years. Whether it is overhead on the ground or buried underground. Whether it is welding or flange connection during installation, it is safe, reliable, fast and convenient, without anti-corrosion, labor-saving and labor-saving, fully reflecting the advantages of "energy saving, environmental protection, economy and efficiency" of ultra-high molecular weight polyethylene pipeline.
