How to solve problem pickling and passivation of stainless steel reaction kettle

Stainless steel safe and reliable to use, selection of high quality, stainless steel belong to consumables, stainless steel because of its unique microstructure and surface passivation films, makes it generally difficult with media reaction and corrosion, reactor is not under any conditions, not be corroded. Pickling and passivation of stainless steel cream is best used for pickling and passivation of stainless steel welded joints, remove the oxide during welding and the Department is in passive state, improved surface quality full corrosion resistance of stainless steel welding, and extend equipment life. Metal stainless steel reactor pressure vessels within the acid cleaning and passivation. Corrosive media and incentives (such as spatter, slag cut and scratch) existing conditions, stainless steel can also be slow with the corrosive medium of chemical and electrochemical reactions are corroded, and under certain conditions the corrosion speed rusting, pitting and crevice corrosion in particular. Corrosion mechanism of electrochemical corrosion of stainless steel parts.
