Polyethylene (PE) pipes are used in a large number of water supply, gas engineering, etc. First, its excellent physical properties, mainly characterized by good rigidity, good flexibility, no water absorption, non-toxic and tasteless, normal temperature Good acid resistance, alkali, salt, organic solvent, good cold resistance and good creep resistance. Second, long-lasting long-life, corrosion-resistant, buried pipes in the temperature range of -60 ° C -60 ° C safely used for more than 50 years. Third, the larger conveying flow pipe wall is smooth, which can increase the flow rate of the medium and increase the flow rate. Compared with the same metal pipe, it can transport more flow and save power consumption. Fourth, significant economic benefits are low in cost and investment is small. Compared with metal pipelines, it can reduce the comprehensive investment of engineering by about 1/3, and the small-diameter pipe that can be coiled can further reduce the project cost. The fifth is convenient construction performance, light weight, density is only 1/8 of steel pipe, easy to handle, easy to bend, simple welding process, small amount of earthwork, no need for anti-corrosion treatment, fast construction speed. Sixth, the excellent stress-resistant cracking polyethylene pipe has better stress crack resistance than the steel pipe. In engineering applications, the leakage and bursting probability of the pipe can be greatly reduced, and the safety of gas transportation can be increased. The polyethylene (PE-80, 100) pipe produced by our company is reasonable in price, complete in specifications and fast in delivery, and is well received by users.
