Abstract: The B30 copper-nickel alloy pipe is widely used in the marine heat exchange equipment and seawater pipe system due to its good seawater corrosion resistance, but the corrosion and leakage of the pipe caused by film failure occurs frequently during its service under complex working conditions. In this study, the corrosion resistance mechanism and evolution process of the B30 copper-nickel alloy pipeis surface coating are analyzed, the failure mode and influencing factors of the alloy's surface coating are expounded, and a comprehensive treatment suggestion for failure control and maintenance of the B30 copper-nickel alloy pipe are proposed.
