Large items that cannot be immersed in tanks can be treated through spray pickling. This method can be applied to objects up to 4 x 4 x 20 meters. With a portal crane having a capacity of 10 tons, these items can be lifted into the facility for processing.
During spray pickling, a thickened pickling solution containing an indicator color is sprayed onto the object. The pickling time varies from 3 to 4 hours depending on the steel alloy and material thickness.
After the reaction time, the object is high-pressure washed until it is completely clean. All of these procedures are carried out in our pickling center, where both the acid and the wastewater are collected and processed in an internal purification system.
