Valves for Crude Oil Service
Crude oil is a complex mixture of hydrocarbons, water, gases (including H₂S), sediment, and wax. Corrosivity depends on H₂S and CO₂ content (sour crude), water cut, chloride content, and temperature. API 6D ball valves dominate pipeline crude service.
Pressure Range
5–250 bar (pipeline to wellhead)
Temperature
Ambient to 180°C (refinery crude distillation up to 350°C)
Industries
Oil production, Petroleum refining, Crude oil pipelines
What valves are used for Crude Oil service?
API 6D trunnion mounted ball valve are recommended for Crude Oil service: Pipeline standard for crude - proven in HPHT crude service.
Key Properties - Crude Oil
- Sour crude (>0.05 mol% H₂S) requires NACE MR0175 materials
- Wax deposition at low temperatures - pigging required
- Water cut increases with field age - raises corrosion rate
- Naphtenic acid corrosion above 220°C in distillation
- High pour point crude may solidify in valve body

Material Compatibility - Crude Oil
Ratings are indicative. Actual compatibility depends on concentration, temperature, velocity, and presence of contaminants. Always consult corrosion tables or a materials engineer.
| Material | Rating | Notes |
|---|---|---|
| Carbon Steel (WCB/A105) | Good | Standard for sweet crude. NACE MR0175 hardness limits for sour service. |
| SS 316L | Good | For sour crude where pitting resistance is needed. Not required for sweet crude. |
| Duplex 2205 | Excellent | Sour crude with H₂S - superior to 316L with better H₂S cracking resistance. |
| 13Cr / Super 13Cr | Good | Common for moderate sour service in oil production wells. |
| Inconel 625 | Excellent | For highly sour or high-temperature naphthenic crude. |
| Monel 400 | Good | For high H₂S content. |
| Rubber-lined | Poor | Crude hydrocarbons attack most elastomers. |
