UHMW-PE pipes has superior performance over conventional HDPE pipe, such as very highwear resistance,impact resistance, yield strength, self-lubricating, anti-adhesion, low temperature resistance and excellentchemical resistance. The above advantages makingUHMWPE ideal for applications for mineral slurry transport,dredging, chemical fluidtransport.
UHMW-PE pipe is a new type of engineering plastic pipe with excellent comprehensive properties, which can be widely used in the transportation of various powders, slurries, fluids and gases, and has broad market potential. It can solve the problems of serious pipeline wear, corrosion and scaling in the transportation of large-scale and multi-variety industrial materials. UHMW-PE pipes can be substituted for the traditional metal pipes, for it is difficult to meet the requirements.
The Report of Experimental Research on Wear of Plastic Pipes issued by General Research Institute for Nonferrous Metals points out that: the following four kinds of pipelines with different materials are tested under the same conditions of pipe diameter, flow rate, experimental material and concentration.
The results are as follows: The average annual wear thickness of glass fiber reinforced polypropylene pipe is 11.5424mm/year: Engineering grade polypropylene pipe (PP) is 13.5828mm/year; UHMW-PE pipe is 5.0104mm/year; Steel pipe (A3) is 36.2424mm year; The experimental results show that the wear resistance of UHMW-PE pipe is seven times as much as that of steel pipe. The unique molecular structure of UHMW-PE pipe has the advantages of extremely high anti-sliding friction and light weight. The unit pipe length is only one eighth of the weight of the steel pipe, which makes loading, unloading, transportation and installation more convenient. The aging and embrittlement rate of UHMW-PE pipe is very slow, and the aging resistance is superior to PE100. Its mechanical properties are only reduced by 20% after burying 50 years. The UHMW-PE pipe is light, flexible, convenient to transport and install, low in cost, and safe and reliable in linking. The impact strength of UHMW-PE pipe can reach more than 120KJ/M2, which is 10 times as high as that of PE.
