What are the specific requirements for air separation and liquid oxygen pipeline piping?

The oxygen generation station design specifications have some regulations, which can be consulted. Degreasing is required; while ensuring compensation for hot and cold deformation, minimize elbows to avoid vaporization; avoid inverted U-shaped structures to prevent freezing; set a safety valve between the two valves; try to avoid using PTFE gaskets; do a good job Insulation; where discharge outlets are required, safety of discharge should be ensured; warning signs should be set up.
