Valves for Power Generation (Thermal, Gas, Hydro) — Shanghai

Yes. Vajra Industrial Solutions supplies Gate Valve (High-Pressure Steam), Globe Valve (Steam Isolation / Control), Safety Relief Valve (IBR / ASME Sec. I), Check Valve (BFW / Feedwater) for power generation (thermal, gas, hydro) 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 power generation (thermal, gas, hydro) in Shanghai, the applicable standards are: ASME B16.34 (Class 600–2500), ASME Section I (Boiler valves), ASME Section VIII (Vessel PRV), API 526, IBR (Indian Boiler Regulations), IS 6392, ASTM A217 WC9 / C12A (P91), B31.1 Power Piping. 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.

IBR (Indian Boiler Regulations, 1950) is the regulatory framework for boilers and steam vessels under the Indian Boilers Act. All valves on steam lines with pressure above 3.5 kg/cm² (0.35 MPa) and temperature above 99°C require IBR certification. This includes: boiler drum safety valves, main steam stop valves, feed check valves, blowdown valves, and all steam isolation valves in the turbine hall. IBR documents required: Form III-C (chemical and mechanical test certificate for material) and Form III-E (hydrostatic test certificate for the finished valve).

A217 WC9 (2.25Cr-1Mo) is used for high-pressure steam valves up to 566°C (1050°F) and is standard for most subcritical (Main Steam temp ~538°C) and conventional supercritical power plants. ASTM A217 C12A is the cast equivalent of P91 (9Cr-1Mo-V) forged material and is used for ultra-supercritical (USC) plants where main steam temperatures reach 600–620°C. P91/C12A has superior creep strength but requires more stringent PWHT and welding controls.
