ActiveGrooved metal gaskets with covering layers for pipe flanges—Part 1：PN designated
管法兰用金属齿形组合垫片 第1部分：PN 系列
Application Summary AI generated
This standard specifies the dimensions, materials, and performance requirements for grooved metal gaskets with covering layers used in pipe flanges under PN (pressure nominal) designations. It is applied in industrial fluid systems, such as petrochemical, power generation, and general pipeline installations, to ensure leak-tight sealing under high-pressure and high-temperature conditions. The standard is critical for procurement and engineering design of flange joints in pressure-containing piping systems.
