Application Summary AI generated
GB/T 9122-2010 specifies the dimensions, materials, and technical requirements for loose plate steel pipe flanges with lapped pipe ends, pressed collars, and pressed collars with long necks. It is applied in industrial fluid piping systems, such as chemical, petrochemical, and water treatment facilities, where flanges need to be easily disassembled for maintenance or where pipe alignment is critical. The standard ensures interchangeability and sealing performance in low-pressure applications, particularly when connecting pipes made of different materials or requiring frequent inspection.
