Batch Units Pickling Plants
Shivas
Shivas builds pickling lines for the treatment of batch units. These batch units, which are arranged in cages or in special suspension arrangements, are dipped into the pickling acid or will be sprayed with the acid.

Hereby individual solutions are prioritized. Both the form of the batch unit and the specific material standards require targeted and exact estimation of the possibilities.
Shivas manufacture chemical Containment Tanks to customers’ exact requirements. These can also incorporate integral lip extraction to facilitate the efficient removal of fumes, especially where the chemicals are heated. Tank heaters can be installed in a recessed base to assist in more uniform heating of the chemical when compared with the side mounted heater elements available. We manufacture and install all tank drainage pipework, extraction ductwork and fume scrubbing systems.

Tube Pickling / Structure Pickling Plants
Shivas builds tube pickling lines also called compact units for low throughputs or completely tunneled pickling lines with traversing mechanism or complex system control. The compact pickling line is designed for small space requirements and simple operability. If required a wastewater and a exhaust air treatment unit are integrated into the plant.

Pre-manufactured modules, which allow an extremely short construction time, enhance the concept. Compact pickling lines can be used for simple applications which require only approximately 2-3 treatment stages. Pickling plants with several baths of diverse treatment stages are built for higher throughput efficiencies.

The following treatment stages could be designed :
  • Degreasing
  • Rinsing
  • Hydrochloric acid pickling bath
  • Sulfuric acid pickling bath
  • Activation
  • Passivation
  • Saponification

Depending on the throughput efficiency multiple immersions have to be planned per stage. For the optimal use of the process levels, Shivas plans an intelligent control of the immersions. This control system calculates the optimal treatment sequences according to the principle of logic functions and controls the plant according to that calculation.
Wire Pickling Plants
Shivas
Since many years Shivas engineers are working in the field of wire pickling lines in continuous operation or immersed.
Shivas builds wire pickling lines also called compact pickling lines for lower throughput or complete tunneled pickling plants with carrier and complex process control. The compact pickling line is designed for small space requirements and simple operability. For the collection of the arising vapor the pickling goods are permanently exhausted by a traveling fume hood. If required a wastewater treatment and an exhaust air treatment are integrated into the unit. Prefabricated modules, which allow an extremely short time of construction, enhance the concept.

Compact pickling lines can be used for simple applications, when only 2-3 treatment stages are necessary. For higher throughput efficiencies pickling plants with several tanks of diverse treatment stages are planned.

The following treatment stages exist :
  • Degreasing
  • Rinsing
  • Hydrochloric acid pickling bath
  • Sulfuric acid pickling bath
  • Activation
  • Passivation
  • Saponification
