Dear sea friends! As the title indicates, some pinholes were detected on the surface of the austenitic stainless steel containers in our factory (used with acidic media) via PT testing. What type of corrosion is responsible for this phenomenon?

Stainless steel is not resistant to chloride ions. I’m not sure about the conditions in which your pipes are used

Reply to 4# tqg317: The medium is vinyl chloride; are there any good anti-corrosion measures available?

Reply to 5#: I’m H, kind-hearted. I recommend using duplex stainless steel, as it has a high molybdenum content and strong resistance to chlorine
