Pickling

Damage to the protective passive layer (chromium oxide layer) on Stainless steel components, caused by mechanical and thermal processing (e.g. grinding, brushing, Laser cutting, welding, etc.), leads to the formation of corrosion after only a short time. The best method to prevent this is pickling for high-alloy stainless steels with at least 16% chromium content.

Performance data

Part sizes up to 1,200 x 1,600 x 5,500 mm
Piece weights small pickle: up to max. 200 kg
spray pickling : up to max. 1,300 kg per trolley (4 pieces in total)
Only high-alloy, stainless steels with at least 16 % chromium can be pickled.
For simple, ferritic steels, we recommend glass bead blasting or grinding.

Procedure

The whole thing works like a big oversized dishwasher. The parts are transported into the cabin on rail wagons with baskets, suspended frames or bulk supports. After the degreasing and pickling processes, the detergent residues are removed again by rinsing and vacuuming. A considerable amount of manual work is eliminated.

The processing is also characterised by the fact that it is carried out by hand:

through low consumption of stain
through uniform and effective wetting of large and small parts
through constant contact of the pickling solution with oxygen
and therefore more effective pickling results than with immersion pickling
