Which has better sealing performance, PTFE-lined pipes or steel pipes?

PTFE-lined pipes can only be connected using flanges section by section, resulting in numerous potential leakage points. Steel pipes are generally welded. If steel pipes can be used, then there’s no need for PTFE lining. However, tetrafluoro pipes have excellent corrosion resistance.

It mainly depends on what fluid is in your pipeline; if steel pipes can be used, there’s no need for PTFE-lined pipes, and the price difference is also significant
