Abstract
Tests on galvanized steel pipe were conducted which showed that the zinc in the coating behaved as cathode when submerged in hot tap water. This cathodic behavior of zinc could, in general, be definitely established only at temperatures above about 70° C. The experimental results tend to clarify a number of apparently unusual corrosion phenomena observed in practice with galvanized pipe used in hot water service.Keywords
