Low temperature resistant gas delivery uhmwpe pipes

Ultra high molecular weight polyethylene pipe（UHMWPE Mining pipe、UHMWPE Dredge Pipe、UHMWPE Roller Pipe）, as a new type of engineering plastic pipe with excellent comprehensive performance, can be widely used in conveying various powders, slurries, fluids, and gases, and has broad market potential. It can solve problems such as severe wear, corrosion, and scaling of pipelines in the transportation of large quantities and multiple types of industrial materials. The requirements that traditional metal pipelines are difficult to meet can be replaced by ultra-high molecular weight polyethylene pipes. The "Research Results Report on Plastic Pipeline Wear Experiment" of Beijing Nonferrous Metallurgical Design Institute points out that the following four different materials of pipelines are tested under the same pipe diameter, flow rate, experimental material, and concentration conditions, The results are as follows: the average annual wear thickness of glass fiber reinforced polypropylene pipes is 11.5424mm/year; engineering grade polypropylene pipes (PP) are 13.5828mm/year; Ultra high molecular weight polyethylene pipes 5.0104mm/year; Steel pipe (A3) 36.242424mm annually; The experimental results show that the wear resistance of ultra-high molecular weight polyethylene pipes is seven times that of steel pipes. The unique molecular structure of ultra-high molecular weight polyethylene pipes has the advantages of high anti sliding friction and lightweight. The unit pipe length is only one eighth of the weight of the steel pipe, making loading, unloading, transportation, and installation more convenient. The aging speed and embrittlement speed of UHMWPE pipe are very slow, and its anti-aging performance is better than PE100. After 50 years of underground use, its mechanical property is only reduced by 20%. It is light, flexible, convenient for transportation and installation, low in cost, and safe and reliable in connection. The impact strength of ultra-high molecular weight polyethylene pipes can reach over 120KJ/M2, which is 10 times that of PE.
