How to deal with rusted oxygen pipelines in air separation units that have been out of use for a long time?
Measure the wall thickness; replace it if it needs to be changed. If it meets the requirements, proceed with rust and degreasing treatment~~
During operation, the air compressor is used for extensive purging, and the purging process continues until the target criteria are met. After parking, it is generally protected by nitrogen filling.
By rust, you’re referring to carbon steel pipes used for external compression, right? Stainless steel pipes shouldn’t have this problem. It depends on the pipe diameter; if it’s very long, it’s best to remove it, treat it, and then reinstall it – safety first.
