The device usually includes parts such as a pickling tank, a passivation tank, a cleaning system, a heating system, and a control system. During the pickling process, the oxide layer on the surface of stainless steel is dissolved by the acid solution, exposing the pure metal surface; the passivation process forms a dense oxide film to improve the corrosion resistance of stainless steel. This device is widely used in the surface treatment of stainless steel pipes, plates, parts and other products to ensure that the products have good protective performance during subsequent use.
