Chemical industry

ChemieiconThe production of chemical products poses special challenges for industrial plants. Enormous temperatures, high pressures and, in particular, aggressive materials attack the stainless steel surfaces. Corrosion protection is always the focus here, in addition to the optimum cleaning capacity of, for example, mixing tanks and/or tube systems.
The surface is also of great importance in production areas with heat exchangers. A heat exchanger with deposit formation can no longer transmit the energy optimally so that this circumstance will have an effect on energy costs in the medium term.

The optimum surface finish

For long-term operation of the plants in the chemical industry, the surfaces should be free of production-related welding tarnish colours and should be unable to form any production-related deposits. The characteristic passive layer of the stainless steel is formed only with undisturbed, passive surface conditions. A pickling treatment after welding work is therefore always recommended. A versatile method of surface treatment is electropolishing. Surfaces treated in this way have extensive functional properties:

  • Reduced roughness (Ra)
  • Micro-smooth
  • Minimisation of the real surface
  • Easy to clean
  • Reduced film propensity
  • Metallically pure & chemically passive
  • Increased corrosion resistance

Services for the chemical industry

Chemical pickling processes

We can work on the components by means of traditional bath pickling, as well as by using spraying or circular methods. Small local welding seams are treated with pickling paste.

An overview of the benefits for you:

  • Machining of workpieces of any size (pickling baths up to 80,000 litres)
  • Pickling chemicals for every application from our own production
  • Complete processing documentation
  • Delivery of pickling equipment and spraying equipment + accessories

Here you can get comprehensive information on chemical pickling.
