In China's municipal pipe market, sewage pipes and gas pipes are its two largest application markets. The chemical name in Chinese is polyethylene. The material is widely used in the field of water supply and drainage manufacturing due to its high strength, high temperature resistance, corrosion resistance, non-toxicity and wear resistance. Because it does not rust, it is an ideal pipe material to replace ordinary iron water supply pipes.
Therefore, the National Bureau of Standards has made a large number of revisions in the new standard, stipulating different levels of water supply pipes and corresponding pressure strengths, and removing the tensile strength performance in the old standard and increasing the elongation at break. A rate greater than that emphasizes basic toughness.
