Stainless steel reactor in the use of the process of pickling passivation, in order to extend the use of the reactor body and reduce the number of reactor failure.

Stainless steel material is safe and reliable, material quality is excellent, but stainless steel is consumable after all, stainless steel because of its special metallographic structure and surface passivation film, so that it is more difficult to react with the medium in general and corrosion. However, the stainless steel reactor in a special environment, the kettle body maintenance must also be processed.

Stainless steel pickling passivation paste, suitable for pickling and passivation of stainless steel welded joints, remove the oxide skin generated during welding and make the place in a blunt state, improve the surface quality and give full play to the corrosion resistance of stainless steel welding, extend the service life of the equipment. The stainless steel reactor is suitable for the pickling and passivation treatment inside the stainless steel pressure vessel. In the presence of corrosive medium and inducement (such as scratches, spatter, slag, etc.), the stainless steel kettle body can also be corroded by slow chemical and electrochemical reactions with corrosive medium, and the corrosion rate is quite fast under certain conditions and corrosion phenomenon occurs, especially pitting corrosion and crevice corrosion, which requires special attention.
