Valves for Oil & Gas Pipelines — Shanghai

Yes. Vajra Industrial Solutions supplies Trunnion Ball Valve, Slab Gate Valve, Dual-Plate Check Valve, DBB Ball Valve for oil & gas pipelines applications in Shanghai, Shanghai Municipality. Shanghai is China's premier industrial hub — Sinopec Shanghai Petrochemical at Jinshan (15+ million TPA integrated refinery-petrochemical), Shanghai Chemical Industry Park (SCIP, hosting BASF, Huntsman, Covestro, Evonik, and 300+ chemical companies), and Baowu Steel's Baoshan Works (7 million TPA, China's largest steel complex) represent the highest concentration of API and ASME valve demand in Asia; these facilities source API 6D Class 600–2500 trunnion-mounted ball valves, ASME B16.34 gate and globe valves in WCB and CF8M, and NACE MR0175 sour-service valves, while Yangshan Port — the world's largest container port by throughput — drives procurement of marine-grade and seawater-resistant duplex stainless butterfly valves. We offer export documentation and delivery to Shanghai in 7–14 business days with full documentation and third-party inspection.

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

Standard stock sizes: export documentation and delivery to Shanghai 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.

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.

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.
