Can the local surfaces of operating natural gas and oxygen pipelines be rust removed and repainted?
Thread Content
Since the project is located by the sea, the pipelines are severely corroded. I would like to ask everyone whether it is possible to locally grind and remove rust from the natural gas and oxygen pipelines that are in use If possible, are there any standard documents?
Oxygen pipelines come in two pressure types: 0.045 MPa for DN1.2m and DN700, and 1.2 MPa for DN250
It’s definitely not allowed; hitting or similar actions are strictly prohibited. It’s absolutely essential to prevent sparks or excessive static electricity from forming inside the pipes
Yes. However, there is a requirement to strictly prohibit hitting with ferrous metals and to ensure fire and explosion safety in environments where sparks must be avoided. Because tasks of this kind are issued as a \"General Work Permit for Entering Production Equipment,\" not as a \"Hot Work Permit.\" When using power tools for rust removal, a fire operation permit and an electrical operation permit are required.
Well, I think the same way, but since the factory can’t have its gas supply cut off for long periods of time...
Have there been any successful cases like this in reality? Also, do you have any written documents? Thank you!
