Dissimilar metals for flange/bolt connections
Dissimilar metals for flange/bolt connections
(OP)
I have had a question from a client, in which he expressed concern that a vessel had used stainless steel bolts on carbon steel red oxide primered channel cover flanges. He was concerned that the dissimilar metals would have corrosion problems. It seems to me that stainless bolts would not have greater corrosion issues than galvanized carbon steel bolts. Am I missing something (carbon contamination perhaps?). Also, this installation is inland and not around any seawater.

Does galvanic corrosion cause significant problems for inland non-submerged applications?
