铸铁管法兰 第1部分：PN系列
Application Summary AI generated
This standard specifies the dimensions, tolerances, and technical requirements for cast iron pipe flanges with PN (pressure nominal) designations. It is applied in fluid systems, such as water supply, drainage, and industrial piping, to ensure interchangeability and sealing compatibility between flanges and gaskets. The standard is used by manufacturers and engineers for designing and procuring flanged connections in low-to-medium pressure piping networks.
