Critical Valve Requirements

NACE MR0175 / ISO 15156 compliance for all sour service valves - H₂S partial pressure thresholds define material selection
NORSOK M-630 material qualification - specific hardness limits and chemical composition requirements beyond NACE
Fire-safe design per ISO 10497 for all production valves - metal-to-metal seat backup required in tropical and North Sea environments
SIL 2 or SIL 3 certification for ESD valves - IEC 61508/61511 failure mode and diagnostics documentation required
Cathodic protection compatibility - valves in splash zone or submerged must be compatible with CP system (sacrificial anodes/ICCP)
DNV or Lloyd's Register third-party type approval for safety-critical offshore valves

Express dispatch available for urgent site requirements. Contact us at +91-9979774557 or sales@vajravyuh.com with your specification and required delivery date.
What is NORSOK M-630 and when does it apply?
NORSOK M-630 is the Norwegian standard for Material Data Sheets and Element Data Sheets for Piping Systems, widely used on North Sea offshore installations and increasingly adopted globally by Equinor, Aker BP, and TotalEnergies Norway. It specifies tighter chemical composition limits, hardness caps, and impact testing requirements beyond ASME or API minimum requirements - particularly for duplex stainless steel and carbon steel in sour service. It is mandatory for Equinor-operated platforms and most Norwegian Petroleum Directorate (NPD) licensed fields.
What duplex grade should I specify for offshore seawater service?
For seawater service (cooling, ballast, firewater), specify Super Duplex 2507 (UNS S32750, ASTM A890 Grade 5A) with PREN (Pitting Resistance Equivalent Number) ≥ 40. Standard Duplex 2205 (PREN ≈ 35) is susceptible to crevice corrosion in stagnant seawater above 22°C. For process fluids containing produced water (lower chloride than seawater), Duplex 2205 is usually sufficient. Carbon steel with internal lining is not recommended for offshore seawater - maintenance access is extremely costly offshore.
