What certifications are required for lng & cryogenic service valves in Dar es Salaam?
For lng & cryogenic service in Dar es Salaam, 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.

Express dispatch available for urgent site requirements. Contact us at +91-9979774557 or sales@vajravyuh.com with your specification and required delivery date.
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.
