Corrosion Testing in New York Reservoirs and Investigations of In-Service Corrosion

Source

Immersion tests of various duration were performed on copper-based alloys,nickel-based alloys, cast irons, and stainless steels. Specimens were exposed at two upstate New York reservoirs as well as in a laboratory environment. The type of corrosion as well as the amount of corrosion varied with heat treatment condition and composition of the sample. All stainless steel samples showed minimal corrosion of any kind except a martensitic grade which exhibited crevice attack with attendant pitting. In-service corrosion of water mains has been also examined. Metallurgical failure analysis of cast iron water mains has revealed waterside corrosion to be only a minor contribution to the cause of failure in a majority of the breaks.
