Abstract: To ensure the safety and reliability of liquefied natural gas (LNG) systems, cryogenic globe valves must withstand extremely low operating temperatures of down to −196°C. Temperature field measurements were conducted on DN15 cryogenic globe valves, and temperature data were collected from the packing glands of 235 valves to characterize and verify the temperature field distribution. The results showed that the temperature distribution in the packing area approximately followed...

Abstract: The development of safe and reliable LNG cryogenic valves under extreme operating conditions requires multidisciplinary analysis and design optimization. In cryogenic environments, issues such as low-temperature material embrittlement, seal failure, and structural deformation can readily lead to valve leakage or malfunction. To address the limitations of traditional cryogenic valve design, including disciplinary fragmentation, overly simplified assumptions, and inadequate verification...

Slab gate valves are critical components of choke and kill manifolds in oil and gas drilling operations, primarily used for well shut-in and flow-path switching. A systematic analysis was conducted on the service history of 189 choke-manifold assemblies covering three specifications and both domestic and international brands in the Tarim Basin over a three-year period. The investigation identified abnormal torque as the predominant failure mode of high-pressure slab gate valves, accounting for 55...
