Stainless Steel Acid Pickling and Passivation Stainless Steel Process

Pickling passivation principle:Stainless steel with corrosion resistant performance is mainly due to the surface is covered with a thin layer of the passivation film (about 1 nm).Iron and iron oxide is dissolved earlier than chromium and chromium oxide.The poor chromium layer is removed, causing chromium to be enriched on the surface of stainless steel.The stainless steel pickling passivation technology is varied, and the enterprises should adopt appropriate methods according to different product types and field operation conditions.

Here we take the pickling passivation process of tank tainless steel tas an example:

The main process of pickling and passivation : pre-treatment (purification surface) ------ pickling passivation and washing ---- post-processing (finished product protection).

The main contents of the pretreatment are to purify pickling, passivating the surface of the article, remove the various grease,weld spatter, burr, scale on the surface of workpieces.

Pickling passivation can pickling, passivation treatment separately, it also can be combined simultaneously pickling passivation process.

In the process of separation of pickling and passivation, it is used to soak the workpiece in the acid washing passivation liquid, suitable for the small parts or the internal circulation of the pipeline, linear equipment.

Combined pickling passivation treatment , can use liquid immersion method (suitable range ditto ) , paste can also be used for daubing , because of the convenient daubing paste paste, it can be maintained for a long time without loss and wetness in different positions.Thus ensuring the pickling passivation necessary time , widely used in the pickling passivation treatment for the scene of the large equipment.

The volume of stainless steel storage tank is large, so the overall immersion method can not be used to make the acid passivation, and the acid cleaning passivation liquid also can not be recycled in the tank.Therefore, it can only be used for acid washing and passivation.The pickling, passivation two processes into one step, saving step, ease of construction, and keep the paste in a wet state for a long time, will help to ensure effective passivation pickling time and ensure that the passivation films can be formed compact.

So the whole process for pickling passivation of stainless steel storage tanks: scaffolding set-up - cleaning the surface of the plate - pickling passivation paste daubing- water rinsing - neutral detection (PH value) - pickling passivation quality inspection - drying, sealing, product protection.
