Scope
This document specifies the structural types, technical requirements, materials, test methods, inspection rules, marking, and packaging, transportation, and storage of steel check valves and lift-type check valves used in the oil, petrochemical, and related industries.
This document applies to the design, production, and inspection of steel check valves and lift-type check valves with nominal sizes of DN15 to DN600 and nominal pressures of PN16 to PN400, as well as those with nominal sizes of NPS1/2 to NPS24 and nominal pressures of Class150 to Class2500, suitable for temperatures ranging from -46°C to 550°C, and with end connections in the form of flanges or welding. The design of throttle valves may be referenced for use.
