Shanghai Petrochemical's Black High-Density Polyethylene Special Material Obtains Nuclear Power Application Qualification
On July 28, Shanghai Petrochemical disclosed that its self-developed black high-density polyethylene special material YGH041TLSH has passed the certification of the American Plastics Pipe Institute (PPI). After passing this certification, Shanghai Petrochemical has become the first domestic supplier of high-end polyethylene pipe materials with nuclear power application qualifications, marking a breakthrough in China's long-term reliance on imports for polyethylene pipe raw materials used in nuclear power water supply and drainage systems. Nuclear power pipelines are one of the important supporting systems of nuclear power plants, with significantly higher requirements for material reliability and safety compared to ordinary municipal pipelines. Taking the 813 mm large-diameter pipeline used in the cooling system of a nuclear power plant as an example, its wall thickness is more than twice that of ordinary pipelines, and the design life requirement reaches...
