Corrosion issues in the pressure compressor intermediate tank
Thread Content
The intermediate tank of the compressor in my plant is suffering from severe corrosion, and there are also frequent leaks in the pipelines leading to the second stage. I’ve already installed several clamps at those locations. I would appreciate it if experts could share how they resolved this issue in their own plants: Thank you!
We did the same in the previous cycle: during operation, only patch repairs could be carried out; after shutting down, the pipelines were replaced and the welds underwent heat treatment, ensuring that their hardness was below HB200, which helps to effectively prevent this type of wet hydrogen sulfide stress corrosion cracking.
