What certifications are required for oil & gas pipelines valves in Nanjing?
For oil & gas pipelines in Nanjing, the applicable standards are: API 6D, API 6FA (Fire Test), NACE MR0175 / ISO 15156, ASME B16.34, API 598 (Testing), ISO 14313, API 607.

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 oil & gas pipelines valves to Nanjing?
Standard stock sizes: export documentation and delivery to Nanjing 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.
What valves are required for API 6D pipeline service?
API 6D (Pipeline and Piping Valves) specifies gate, plug, ball, and check valves for pipeline service. The standard covers design, materials, dimensions, testing, and documentation. All isolation valves on a pipeline must be API 6D certified; this is a contractual requirement in ONGC, GAIL, and most oil company pipeline standards.
What is a fire-safe valve and why is it required for pipelines?
A fire-safe valve maintains seat sealing integrity and stem packing containment in the event of an external fire (tested per API 607 / API 6FA). This prevents a valve leak from feeding a hydrocarbon fire. Fire-safe design is mandatory for all valves handling flammable hydrocarbons under Indian OISD standards and most international oil company specifications.
