Anti-corrosion in sewage pipes
Thread Content
I would like to ask whether internal anti-corrosion is required for the sewage pipelines in the LNG process equipment area?
Generally speaking, the sewage pipelines in the natural gas process pipeline area do not need internal anti-corrosion.
I have basically no contact with them. But I understand that it depends on the medium in the pipe. Carbon steel is probably not suitable for highly corrosive pipes. You can consider plastic-lined pipes, cement pipes, etc., depending on the situation.
Pipeline anti-corrosion generally depends on the pipe material and the corrosive liquid inside the pipe.
It shouldn't be used. Yes, it mainly depends on the characteristics of the medium in the pipeline and the properties of the pipeline material.
