PE is the English abbreviation of polyethylene, and the application range of the common PE pipe water supply pipeline is the temperature lower than 40 ℃, so that the PE pipe water supply pipeline cannot be used for a hot water conveying pipeline. PE pipe is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and the micro-thin section is semitransparent to a certain degree. PE has excellent resistance to most domestic and industrial chemicals. Certain classes of chemicals cause chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The plastic pipeline in China develops rapidly and the quality is improved continuously. Plastic pipe industries mainly including polyvinyl chloride (PVC-U) pipes, Polyethylene (PE) pipes, and polypropylene (PP-R) pipes have been primarily formed.
