We offer export documentation and delivery to Sarnia in 7–14 business days with full documentation and third-party inspection.
What certifications are required for marine & offshore service valves in Sarnia?
For marine & offshore service in Sarnia, the applicable standards are: API 6D, NORSOK M-710 (Elastomer qualification), DNV-OS-D101 (Marine systems), Lloyd's Register, NACE MR0175 / ISO 15156, API 607 (Fire test), ASME B16.34, ISO 14313. All valves are supplied with full documentation including material test reports (EN 10204 3.1/3.2), pressure test certificates, and dimensional inspection reports. Third-party inspection (TPI) by EIL, Bureau Veritas, Lloyd's Register, or the client's nominated inspector can be arranged.
What is the delivery time for marine & offshore service valves to Sarnia?
Standard stock sizes: export documentation and delivery to Sarnia in 7–14 business days. Custom sizes and special materials (Duplex, Hastelloy, P91): 4–8 weeks manufacturing lead time. Express dispatch available for urgent site requirements. Contact us at +91-9979774557 or sales@vajravyuh.com with your specification and required delivery date.
Why is standard SS 316 not suitable for offshore seawater service?
Stainless steel SS 316 (UNS S31600) has a PREN (Pitting Resistance Equivalent Number) of approximately 25, which is insufficient to resist pitting and crevice corrosion in seawater (chloride concentrations 18,000–35,000 ppm). Localised pitting can initiate within weeks in warm seawater. Duplex stainless (UNS S31803, PREN ~35) and Super Duplex (UNS S32750, PREN ~42) provide the corrosion resistance needed for continuous seawater service. For subsea and injection applications, Super Duplex is typically specified.
What is NORSOK M-710 and why does it matter for offshore valves?
NORSOK M-710 is a Norwegian offshore standard specifying qualification testing for non-metallic sealing materials (elastomers and thermoplastics) used in valves and other equipment on offshore installations, particularly on the Norwegian Continental Shelf. It tests resistance to high-pressure gas decompression, chemical resistance to hydrocarbons, and sour gas exposure. NORSOK M-710 qualification is required by most operators on the Norwegian Continental Shelf and is increasingly specified globally for FPSO and offshore topsides applications.
