Erosion corrosion of heat exchanger tubes in warm, flowing Persian Gulf seawater containing up to 5 ppm of sulfide ions is investigated. Tube samples were made of copper (Cu)-nickel (Ni) alloys (90% Cu-10% Ni and 70% Cu-30% Ni), Ni-Cu alloy (UNS N04400), and Ni-based alloys (UNS N06022, N06030, and S32550). Visual and optical examinations of the internal surfaces of the tubes were conducted to compare the susceptibilities to erosion corrosion attack of the different alloys, taking into consideration the nature of the product films formed.
