White Paper: Current Methodologies & Chemistries Utilized In Effective Passivation Procedures

Chemical cleaning and passivation treatments on stainless steel tubing and equipment are an important aspect in the preparation of surfaces used in corrosive and critical environments. The formation of a higher chromium to iron (Cr/Fe) ratio in the passive layer will result in improved corrosion resistance and lowered rates of iron oxide formation (rouge). Clean process and transfer system surfaces are required to maintain purity of processes and products. A corrosion resistant surface insures continuous fluid quality with a lack of impurities generated at the stainless steel surface.
