What material should a check valve for Propane (C₃H₈ - LPG Component) be?

Carbon Steel (Excellent): Standard for propane storage spheres and pipeline service. SS 316L (Excellent): Optional - better corrosion resistance for propane with moisture. PTFE seals (Excellent): Best for propane. A350 LF2 (Good): Required for cryogenic propane below −29°C. Viton (FKM) seals (Good): Good chemical resistance to propane. NBR seals (Good): Acceptable for propane service at moderate temperature.

Governing Standards for Propane (C₃H₈ - LPG Component) Service

API 607 (fire-safe, mandatory)NFPA 58 (LPG code, USA)OISD-116 (India LPG storage)API 6D ASME B16.34EN 13786 (European LPG valves)

What to Avoid in Propane (C₃H₈ - LPG Component) Service

Non-fire-safe valves in propane storage areas
Cast iron valves for propane service - brittle failure risk

Service Considerations

ESD (emergency shutdown) valves mandatory on all propane storage sphere nozzles per OISD-116 (India) and NFPA 58 (USA)
Fire-safe design API 607 mandatory - propane vapour cloud explosion risk
Pressure relief valves must be sized for fire case heat input to storage vessel
Cryogenic storage: A350 LF2 or SS 316L bodies required for extended-bonnet valves
