Application Summary AI generated
GB/T 9118-2010 specifies the dimensions, tolerances, materials, and marking requirements for loose hubbed steel pipe flanges with a welding neck collar. These flanges are used in fluid systems, particularly in industrial piping applications where frequent disassembly is needed, such as in chemical, petrochemical, and water treatment plants. The standard ensures interchangeability and sealing performance for flanges connecting pipes or valves in low-pressure to medium-pressure environments.
