Learn from the advanced practices of the *Brothers section; there are prizes for correct answers – any answer earns a reward, allowing us to grow and mature through these Q&A sessions. Briefly; additional comments are welcome: Inspection and maintenance of process oxygen pipelines (1) Oxygen pipelines must be degreased and cleaned, and thoroughly purged. During maintenance, the flange connections of the disconnected oxygen pipelines should be sealed to prevent debris from entering ； (2) Regularly inspect the anti-static measures to ensure that all anti-static flange crossconnections are in good condition. (3) Strengthen the inspection of oxygen pipelines, and address any leaks as they are detected ； (4) The oxygen tube is pressurized with high-pressure nitrogen before receiving oxygen, to isolate it from the process system.
As a combustion aid, oxygen possesses strong oxidizing properties; in actual operation, oxygen pipelines are highly prone to combustion and explosion, which plays a crucial role in the safe operation of the facility
