Metal Pickling Plants

Dipping systems for surface treatment of

  • tubes & pipes
  • rods & bars
  • wire coils
  • contract pickling
The tanks can be used for all kinds of pickling agents, including mixed acids composed of hydrofluoric, sulphuric and nitric acid (HF, H2SO4 and HNO3, respectively). Of course, they serve as well as tanks for rinsing, degreasing, passivation etc. We deliver the whole plant.
KVK tanks have been developed and improved for over 20 years to meet the highest demands! This experience pays off in the highly corrosive atmosphere in pickling plants, where mixed acids are employed.

  • long service life of the components
  • compliance with the strictest environmental regulations
  • minimisation of production costs

Complete Hot-Dip Galvanising Plants

Encapsulated Pickling Plants with the KVK System
Heating up the pickling baths yields a considerable reduction of process time and hence a reduction of the number of pickling tanks.

However, in traditional open plants, the benefits that can be derived from this effect are very limited, since the higher bath temperatures result in an increase to the acidic emissions and consequently increased corrosion on cranes, the building and stored material. On top of that, workplace safety (maximum working site concentration) cannot be guaranteed even when employing suction systems on the lateral sides of the tanks.

More than 20 plants set into operation worldwide prove the advantages of this system in practice. Koerner is the only plant supplier that can simulate and predict the flow conditions in each encapsulated plant using its own calculation modules.

The automatic crane and other sensitive plant equipment such as pumps and sensors are protected from the emissions. Thus, it is possible to employ the best available instrumentation, an automatic handling system and to run a fully automated pre-treatment plant. During regular operation, no personnel work inside the pre-treatment plant.

  • A sole source supplier
  • Use of the highest-quality components
  • Plant concepts specifically adapted to the requirements of the customer
  • Low production costs
  • Low maintenance costs
  • Perfect galvanising quality
  • Minimum zinc consumption
  • Compliance with the DAST guidelines
  • Training of production personnel

KVK tanks have been especially designed to withstand the rough working conditions in tube pickling plants. Tank walls are made of our proven KVK panels, which are manufactured as one continuous seamless piece suiting the individual tank geometry. Thus, there are no weld seams that would cause additional stress.

Special manufacturing processes and the robust design of KVK tanks guarantee an operational life span far above average.

Numerous reference plants both in Europe and overseas, some of which have been in operation for 10-20 years now, prove the chemical and wear resistance of our KVK tanks.

KVK tanks can be equipped with a variety of optional equipment.
