Why do oxygen pipeline valves and similar components need to be degreased?

Why do oxygen pipeline valves and similar components need to be degreased? Those pipes also need the same treatment; is an inert gas necessary?
During the transportation of oxygen, if grease is present, friction occurs as the airflow moves and comes into contact with the pipe walls; this friction generates a large amount of heat, which can lead to an explosion. Therefore, the valves in the oxygen pipeline must be treated with grease. . .
The main thing is that there must be no oil stains, otherwise explosions could occur; I’m not too sure about the other aspects. Inert gases aren’t necessary
Thanks, Ang. I see now, it’s like that:victory::lol Thanks
What was said upstairs is correct; generally, oxygen cylinders are required not to come into contact with oils, as there is a concern that this could cause an explosion；
Because a liquid oxygen leak passing through grease can trigger a violent oxidation reaction that causes the grease to burn or even explode. . Moreover, asphalt pavements are also not allowed within 5 meters of the liquid oxygen storage tank.
Oxygen has strong oxidizing properties, and the ignition point of flammable materials is much lower in a pure oxygen environment than in air. Static electricity can be generated due to sudden opening or closing of valves, excessive flow velocity of the oxygen fluid in dead corners, as well as impacts and external friction, which may lead to combustion or explosion in a relatively enclosed environment.
Oxygen, hydrogen, chlorine – all of these need to be thoroughly degreased.
