Cryogenic Valves for LNG Service - ValvTechnologies

According to most specifications, cryogenic valves for LNG service must be fire tested. Unfortunately, the soft goods in most cryogenic ball valves will not pass the industry standard fire tests. Additionally, some metal seated valves which claim to be "inher-ently fire safe" have not actually been fire tested.

Cryogenic Liquids | Office of Environmental Health and Safety

For this reason, pressurized cryogenic containers are usually protected with multiple pressure relief devices. Vaporization of cryogenic liquids (except oxygen) in an enclosed area can cause asphyxiation. Vaporization of liquid oxygen can produce an oxygen-rich atmosphere, which will support and accelerate the combustion of other materials.

Friction welding - Wikipedia

Friction welding (FRW) is a solid-state welding process that generates heat through mechanical friction between workpieces in relative motion to one another, with the addition of a lateral force called "upset" to plastically displace and fuse the materials. Because no melting occurs, friction welding is not a fusion welding process in the traditional sense, but more of a forge welding technique.
