Governing Standards for Propylene / Propene (C₃H₆) Service

What to Avoid in Propylene / Propene (C₃H₆) Service

Non-fire-safe valves in propylene storage areas
Valves with dead legs that could allow propylene polymerisation

Service Considerations

Fire-safe API 607 design mandatory - propylene is a Class IA flammable liquid
ESD (emergency shutdown) valves required on storage sphere connections
Low-temperature service at −47°C requires A350 LF2 or SS 316L bodies
Potential polymerisation in dead legs - minimise dead volume in valve design
