JB/T 450-1992 PN16.0～32.0MPa forged angle high-pressure valves, pipe fittings and fasteners technical conditions

This standard specifies the structural form, technical requirements, test methods, inspection rules, etc. of forged angle high-pressure valves. This standard applies to flange-connected angle stop valves, external thread angle stop valves, welded angle stack stop valves, pipe fittings and fasteners with nominal pressure pN16.0~32.0MPa and nominal diameter DN3~80mm; DN50~ 200mm balanced angle stop valve and throttle valve. The medium temperature is -30~200℃, and the medium is water, nitrogen-hydrogen mixed gas, urea or methylamine liquid, etc. Forged high-pressure valves with other structural forms and high-pressure valves with temperatures between 201 and 400°C can also be implemented with reference to this standard.
