The ASME B16.11 A350 LF2 Socket Weld Tee is a high-pressure branching fitting specifically engineered for low-temperature and cryogenic service. Forged from fine-grained carbon-alloy steel, it is normalized to ensure exceptional toughness down to -46℃ (-50°F). The 3000# rating provides the strength required for high-pressure gas headers, LNG processing, and refrigeration units. Its socket design allows for rapid, precise pipe alignment and a permanent, leak-proof seal in extreme environments.
