Valves used in hydrogen applications should be made of hydrogen-compatible materials, such as austenitic steel (e.g., 316/316L), to prevent issues like metal embrittlement, increased pressure, and internal stresses. Non-metallic components, such as gaskets and lubricants, should also be hydrogen-compatible to ensure optimal performance.
This process is achieved by reducing the boiling point of liquid nitrogen below the LNG storage temperature via nitrogen pressurization and by utilizing LNG …
