Electropickling & Electropolishing

Stainless Steel Solutions


Delmet stainless steel excellence since 1949

Delmet portable systems for the electropickling and electropolishing of stainless steel are a true technological evolution in the stainless steel treatment of welds.

The DLT machines electropickle, electropolish and passivate welds on stainless steel, duplex and superduplex products with an immediate and lasting result.


Portable systems for electropickling stainless steel are a true technological evolution for cleaning welds. With the portable DLT electropickling system it is possible to electroclean, pickle, electropolish and passivate the welds on stainless steel, duplex and super duplex products with immediate and safe results.

Why true technological evolution?

Why electropickle instead of pickling and passivating, as we have always done? Because electropickling and electropolishing with Delmet portable systems means: effectively saving time and money, ensuring flexibility and ease of use thanks to the versatility of the applications, and means obtaining a high quality finish on the welded areas - the areas thermally altered by welding on the stainless steel - and simultaneously achieving effective passivation of all stainless, Duplex and Superduplex steels.

Specific sectors of application:

  • Food and Dairy Machinery
  • Pharmaceuticals and Cosmetics Machinery
  • Packaging machinery and conveyor belts
  • Tanks for Winemaking, Breweries and Olive Oil
  • Bottling and bagging systems
  • Chemical and Oil&Gas plant engineering & piping in general
  • Nautical, furniture and stainless steel carpentry

Why should I use Delmet DLT machines?

Because it would mean effectively replacing pickling and passivating gels - eliminating the problem of acid waste and the disposal of rinsing water containing dangerous environmental pollutants. With Delmet electropickling, the waste is minimised by using a rag to clean up the small quantities of residue from the treated surface and the rag used can be easily managed with the dirty-clean recycling service. The ease of use of Delmet machines has become proverbial, both for use on the bench and on site, and for the well-known qualities of portability and safety of insulation, for the reduced consumption of electrolyte liquid and energy, for the lack of of moving parts and unnecessary cooling, blowing or suction systems. Our machines benefit from an unprecedented current delivery system that ensures a concentration of current to the brush which is transmitted to the surface with fast and excellent results, without overheating the system.

Our compact, powerful and effective machines are the winning choice of the shrewd buyer, having become, given their performance, the benchmark for customers in many sectors of stainless steel processing.
