**Product Material Overview** PE (High-Density Polyethylene) environmentally friendly and healthy drinking water pipelines are made from imported PE100 raw materials and manufactured according to GB/T13663 standards. The products exhibit good weldability and environmental stress cracking resistance, meeting both international and national standards. PE pipelines are primarily used for water supply and drainage, mining pipelines, and the transportation of wastewater and slurry in the chemical and pharmaceutical industries, as well as solid or mixed media. The internal resistance of PE pipes is 25% lower than that of metal pipes, significantly improving transportation efficiency. The raw material sources for PE are abundant. From the molecular formula structure (C2H4), PE has a relatively simple polymer structure. During its development, PE pipes have continually overcome their shortcomings. The heating and welding of PE pipes require a certain operational space and skilled technical expertise. Subsequently, electric heating welding sleeves were invented, which connect two pipe sections or fittings through an electric heating welding sleeve. This connection method is used for connecting PE pipes in trenches or in confined construction spaces. The material properties of PE pipes are also improving, progressing from PE63, PE80 to PE100, and will eventually develop to PE115. PE100 refers to the grade of PE material that can maintain a low strength of 10MPa (MRS) after 50 years at 200°C. PE80 has a strength of 8.0MPa. As the grade of PE material increases, the wall thickness of pipes made from PE115 is lower than that of pipes made from PE100 while still meeting requirements. The reduction in wall thickness decreases the amount of PE material used, lowering costs and facilitating the application of PE pipes in large-diameter pipelines. The connection of PE pipelines requires heating and a specific cooling time, with each welding taking about 20 minutes. The larger the diameter of the pipe, the longer the heating and cooling times, thus extending the installation period for PE pipes.
