燃气用埋地聚乙烯(PE)管道系统 第3部分：阀门
Application Summary AI generated
This standard specifies the technical requirements, test methods, and quality control for polyethylene (PE) valves used in buried piping systems that transport gaseous fuels. It is applied in the design, manufacturing, and installation of PE valves for natural gas distribution networks, ensuring leak-tightness and long-term durability under soil and pressure conditions. The standard is critical for gas utility companies, pipeline contractors, and regulatory bodies to verify valve performance in underground fuel supply infrastructure.
