What are pickling and 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. Pickling and passivation are processes commonly used to enhance corrosion resistance and remove contaminants on stainless steel. Here at Transflow Industrial Services Limited, we are specialists in pickling and passivation treatments.
What is pickling?
Pickling is a chemical treatment whereby we will treat your steel with a chemical solution. Pickling involves nitric and hydrofluoric acid. This process eliminates type 1 rouge and type 2 rouge, impurities, stains, contaminants, and rust or scale from stainless steels.
What is passivation?
Passivation 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. Passivation is achieved by applying a strong oxidizing agent (nitric acid) or a chelating agent (citric acid) to the stainless steel.
Our pickling and passivation treatments 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.
