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
