    What is Passivation?

    As one of the best pickle and passivation companies in the UK, we can assist in a huge range of industrial cleaning including passivation. Stainless steel is protected against corrosion and other damage by a naturally forming passive layer called the Chromium Oxide layer. If this is disrupted or damaged by cutting, welding, heating, grinding or through contact with chemicals, the stainless steel loses its protection against corrosion. The passivation process is a chemical treatment for stainless steel that is proven to enhance and restore the ability of the treated surfaces to be resistant to corrosion. With Transflow, the passivation of stainless steel is achieved by applying a strong oxidizing agent (nitric acid) or a chelating agent (citric acid) to the stainless steel for maximum results.

    derouging and passivation
    derouging

    What is Derouging?

    Although the passivation of stainless steel can improve the corrosive resistance, manufacturing can leave behind several imperfections that it can’t eliminate such as heat tint or oxide scale left behind by welding and heat treating. The pickling of stainless steel is a chemical treatment whereby we will treat your steel with a chemical solution, usually hydrochloric or sulfuric acid and aims to eliminate impurities, such as stains, contaminants, and rust or scale from ferrous metals, copper, precious metals and aluminium alloys.

    Our passivation and pickling services include:

    Quality control with comprehensive RAMS, COSHH reports and support documentation.
    High-quality equipment individual to each job – pumps, tanks, hoses, adaptors.
    Ferroxyl test to confirm the presence of a passive layer after the process.
    Off-site baths and immersion tanks with a clean room for drying, testing and wrapping.
    Vessel entry/confined space access.
    Professional cleaning services if required.
    Paste passivation of small blemishes in clean rooms.
    Control of waste chemicals and disposal according to Environment Agency legislation.
