It is mainly for steel pipelines, which is prone to corrosion reactions, and there is a certain hidden danger to equipment damage after corrosion. After removing all kinds of dirt such as oil, rust, scale, welding spots, etc., the corrosion resistance of steel can be greatly improved.
If there is dirt on the surface of the stainless steel pipe, it should be mechanically cleaned, and then degreased and degreased. The presence of grease on the surface will affect the quality of pickling and passivation. Therefore, degreasing and degreasing cannot be omitted. Alkali, emulsifiers, organic solvents and steam can be used.
Passivation is the last process step in chemical cleaning and is a key step. Its purpose is to prevent corrosion of materials. For example, after the boiler is acid-washed, water-washed, and rinsed, the metal surface is very clean, very activated, and susceptible to corrosion. Therefore, you must immediately passivate the surface to form a protective film on the cleaned metal surface to reduce corrosion.
