Chemical Cleaning and Passivation

RES provides cleaning and passivation services for large and small companies in diverse industries and processes. We follow international engineering standards and practices for the utmost in safety and efficacy.

Passivation: The removal of exogenous iron or iron compounds from the surface of stainless steel tanks and piping by means of chemical dissolution, that will remove the surface contamination but will not significantly affect the stainless steel itself, for the purpose of enhancing the spontaneous formation of a protective, passive, oxide film. These contaminants are potential corrosion sites which, if not removed, result in premature corrosion and ultimately result in deterioration of the component.

There are many variations of passivating solutions and technology. The type of alloy being treated, determines the optimal treatment method.
