Valves for LNG & Cryogenic Service — Baku

Yes. Vajra Industrial Solutions supplies Cryogenic Ball Valve (Extended Bonnet), Cryogenic Gate Valve (Extended Bonnet), Cryogenic Globe Valve (Extended Bonnet), Cryogenic Check Valve for lng & cryogenic service applications in Baku, Baku. Baku is the historic and current epicentre of Caspian oil production — BP's Azeri-Chirag-Gunashli (ACG) field and the 1,768 km BTC export pipeline terminate at SOCAR's Sangachal terminal requiring thousands of API 6D Class 900–1500 trunnion ball valves, fire-safe isolation valves and NACE MR0175 sour-service gate valves, while SOCAR's Heydar Aliyev refinery and Sumgayit petrochemical complex consume corrosion-resistant SS 316 and Duplex 2205 valves for crude distillation and polymer production. We offer export documentation and delivery to Baku in 7–14 business days with full documentation and third-party inspection.

For lng & cryogenic service in Baku, the applicable standards are: BS 6364 (Cryogenic valves), ASME B16.34 Annex F, API 6D, EN 13942, ASTM A350 LF2 / LF3, ASTM A182 F316L, MSS SP-134. 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 Baku 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.

An extended bonnet (also called a top-entry or long-bonnet valve) has an elongated bonnet section that moves the stem packing away from the extremely cold process fluid. This prevents the packing material from being exposed to cryogenic temperature (where it would lose elasticity and leak), and prevents atmospheric moisture from freezing around the packing gland. The extension length is calculated based on the process temperature and the acceptable minimum packing temperature.

For LNG (−162°C) and liquid nitrogen (−196°C): ASTM A351 CF8M or CF3M (cast SS 316/316L) and ASTM A182 F316L (forged). For liquid CO₂ and −46°C service: ASTM A350 LF2 (forged low-temperature carbon steel), Charpy impact tested at −46°C. Standard A216 WCB carbon steel must never be used in cryogenic service below −29°C.
