Summary for cathodic protection buried 316l piping Discussion
Cathodic protection of buried 316L piping is the core question here: Lawrence Goh asks whether polyethylene-tape-wrapped 316L stainless steel pipe buried underground near the sea needs CP, and if so, what type would be suitable in a salty, highly corrosive environment. The excerpt provided does not include any replies or named expert answers, so there is no thread discussion to summarize beyond the question itself. Based on the source shown, the issue is simply whether buried 316L stainless steel near seawater exposure should be cathodically protected despite its corrosion resistance and tape wrap. Because no answers are present in the excerpt, no recommendation can be attributed to a specific responder.

Q. Could any tell me used of stainless steel 316L pipes with polyethylene tape wrapped buried underground require any cathodic protection(CP), if require what are suitable type of CP to be used, the SS316L pipes are buried alongside close to the sea which is very corrosive with the present of salt content.
