摘要：

Corrosion-resistant alloys are commonly used in offshore oil and as production platforms for process piping and internal vessel claddings. The analysis of a leak in Type 316L stainless steel (UNS S31603) piping showed that it was caused by oxidation of the weld root during welding because of insufficient or improper shielding gas at the root side, improper cleaning before and after hydrotesting, and the presence of untreated water in pockets at lower points of the piping system.
