Governing Standards for Crude Oil Service
What to Avoid in Crude Oil Service
- Ball valves with PTFE seats in high-temperature crude above 180°C
- Check valves with rubber discs in crude service
- Globe valves for mainline isolation (use gate or ball)
Service Considerations
- Sour service (H₂S): all wetted metal hardness ≤ 22 HRC per NACE MR0175
- ESDV (emergency shut-down valve) with fire-safe design per API 607
- Pigging requirement: full-bore, no bore reductions
- Antistatic device required for ball and butterfly valves
- Wax-prone crude may need heated valve enclosures
