Dissimilar metallic materials have been used in several piping systems during ship retrofitting. Application of dissimilar alloys may initiate galvanic corrosion of the more anodic, electronegative member that can lead to piping failures. The performance and effectiveness of several galvanic control methods has been monitored in natural seawater using piping mockups for 6--20 months. Results of these methods may provide alternative galvanic corrosion control techniques that may allow selective, reliable use of mixed piping systems with a minimization of shutdowns for removing, inspecting, and replacing system components.
