Derouging

DEROUGING FOR STAINLESS STEEL
But what is Derouging? what is the phenomenon called Rouge?

Rouge is an oxidative phenomenon that appears on the surfaces of stainless steel in austenitic alloy products used for transport, storage and sterilization, for example pipes, autoclaves, tanks and reactors.

The Rouge consists in the coloring of the steel surface ranging from light red to a brown color depending on the quantity and quality of the phenomenon encountered.

It is a particular complex of oxides that forms under the passive layer of stainless steel and in addition to being unsightly, it can also lead to corrosive phenomena over time.

Rouge is a phenomenon that is increasingly becoming a problem for pharmaceutical companies that are subject to strict controls by national and international bodies.

Thanks to its internal research and the equipment at its disposal, Delmet is able to remove this phenomenon and restore the surface of the steel to its original condition.

Removal of the Rouge

Over time, Delmet has specialized in removing the Rouge phenomenon and to date numerous interventions have been carried out for the most important companies. Over the years Delmet has equipped itself with new portable systems of small dimensions that can be brought directly on board the systems to be treated as pipes , sterilization autoclaves, storage tanks, steam production plants and reactors.

The treatment lasts a few hours and is always followed by a passivation to restore the "good" and protective oxide layer on the stainless steel surfaces, making it practically like new.
