Stainless steel is not always as stainless as one would think. When the coating of a piece is damaged, for example if contaminated with iron / welding / torch cutting / work with a grinder, etc., that stainless steel piece’s resistance to corrosion is no longer guaranteed. To restore the anticorrosive properties to the damaged coating, Industry Geel uses a particular technique called “pickling by immersion.” When the piece to be treated is ready, it is immersed in an acid bath for several hours to remove a few microns of impure material, in a process called “pickling.” The basic material is then comes out again without any deterioration or contamination. After this acid treatment, the piece is rinsed with water on all its facets to be restored bare in the atmosphere again. “Passivation,” a totally passive state, is obtained after 24 hours.
Only a few persons in the Industry Geel BU are trained to perform this work. Given the properties of acid, the “pickler” always wears protective gear from head to toe, to minimise the risk of burns and irritation of the skin, eyes, etc.
At SPIE, safety is priority number 1.
The content of the acid bath is renewed entirely every 2 year. “This is done in an ecological manner nowadays. The pickling product and residues are withdrawn and totally destroyed to minimise their impact on nature and the environment. As a Class 1 company, we comply with all the standards and requirements on the matter.”
The Geel pickling bath is one of the largest in Belgium and other welding workshops call on its services to confer stainless properties on their materials.
As the impact of coronavirus on our activities increases and in the face of ever-stricter government measures to halt its spread, SPIE Belgium would like to inform you about the steps it has taken within the organisation.
To this day:
SPIE Belgium has decided not to stop its activities completely, considering that some of these may be essential or even critical to maintaining the activities of companies in critical sectors and essential services that are vital to the smooth running of the country. This is being done, of course, in strict respect of the measures taken by the authorities, and treating the health and safety of our staff, our clients, our suppliers and sub-contractors as a priority.
This unprecedented crisis reminds us of the importance of two of our founding values: responsibility and proximity. By each taking our responsibilities, we will overcome this ordeal.
Drawing strength from our 120 years of experience and from the solidity of the Group to which we belong, we remain confident in the future and in our mutual capacity to adapt and be resilient.
