The exfoliating corrosion which occurs on the steam side of cupro-nickel feed-water heater tubes is described, together with a laboratory investigation designed to study the effect of operational variables such as condensaiion, temperature, pressure, thermal cycling and oxygen admission on the corrosion of cupro-nickel alloys.
Corrosion similar to that occurring on feed-heater tubes could be reproduced only in high-pressure steam containing oxygen. An explanaiion is given of the incidence and mechanism of corrosion and practical remedies are suggested.
