Why Dolvi's Integrated Steel Sector Needs LNG & Cryogenic Service Valves

Dolvi in Raigad district is home to the JSW Steel Dolvi Works, a ~10 MTPA integrated steel plant using blast-furnace and Conarc (scrap-DRI) routes with a captive power plant, air-separation oxygen units, and a dedicated Amba-river jetty; steelmaking, oxygen-plant, and captive-power service drives demand for high-temperature A217 WC6/WC9 gate and globe valves for blast-furnace, coke-oven, and steam duty, abrasion-resistant knife-gate and pinch valves for slag, slurry, and dust-laden lines, oxygen-cleaned valves for air-separation and gas-distribution service, and API 6D ball valves for fuel-gas and utility headers; ASME B16.34, IBR, and EIGA oxygen-service standards apply with degreasing certificates and PMI; Vajra Industrial Solutions supplies JSW Dolvi and its maintenance and EPC contractors with high-temperature, abrasion-resistant, and oxygen-service valve packages with Maharashtra logistics. Key facilities in the Dolvi area - including JSW Dolvi steel complex, Amba river jetty, Pen-Raigad industrial belt - rely on Cryogenic Ball Valve (Extended Bonnet) for their oxygen & industrial gases operations. 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 projects across Maharashtra, with full BS 6364 (Cryogenic valves) and ASME B16.34 Annex F compliance documentation - EN 10204 3.1 material test certificates, API 598 pressure test reports, and third-party inspection co-ordination available for every order.

What is an extended bonnet on a cryogenic valve?

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.

What ASTM material is used for cryogenic valves?

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.
