What is Rouging?
Rouging is a type of corrosion that occurs in some closed water systems made of stainless steel e.g. sanitary water.
There are various theories as to why rouging occurs. The most likely theory is that the passive layer cannot be re-formed if it is worn away in oxygen-poor water. In three different case studies, on three industrial water systems, it has been shown that rouging can be remedied by electropolishing.
