REVIEW OF CORROSION EXPERIENCE WITH COPPER-NICKEL ALLOYS IN SEA WATER PIPING SYSTEMS

A literature survey of prior information on sea water attack on Cu-Ni piping shows that incidence of attack is a function of exposure to polluted water containing sulphides, a condition that occurs at many fitting-out basins. Deposition of copper sulphide on Cu-Ni surfaces is cited as the probable cause of pitting because the sulphide layer is cathodic to the base metal. Stagnation of sulphide-contaminated water accelerates attack. Other deposits such as carbonaceous films formed from residual drawing compounds during tube manufacture, oxides formed during brazing operations and solids settling out from water at excessively low velocities amy also give rise to pitting corrosion.
