Treatment of corrosion resistance of stainless steel pipe surface
by yane Yang Sales Manager There are many ways of anticorrosive treatment on stainless steel pipes. By improving the surface treatment methods and processes of stainless steel pipes, many practical applications can be improved.The first is cleaning stainless steel pipe. It can be cleaned with solvent and emulsion, and chemical cleaning agent is recommended to clean the stainless steel pipe surface, so as to remove oil, dust and similar organic matter, and remove the rust of stainless steel pipe surface and the impurities such as oxide skin. In the same way, it is treated only as surface treatment in anticorrosion production. The auxiliary method.
The second is to use tools to remove rust and to wear the surface of stainless steel pipe by means of steel wire brushes, so as to remove the loose or warped oxide, rust or slag. Manual tool rust removal can reach Sa2 level, power tool rust can reach Sa3 level, if the stainless steel pipe surface attached to solid oxide skin, tool rust removal efficiency is not ideal, no corrosion resistance to the requirements of the anchor depth, this time it is recommended to use chemical treatment to remove rust.
The third is stainless steel pickling, usually using chemical cleaning and electrolysis to do two kinds of acid washing treatment, and stainless steel pipe corrosion resistance only use chemical stainless steel pipe acid washing, can remove the oxide skin, rust, coating, and can also be treated as sand removal after the retreatment.
The fourth is jet derusting treatment. Jet removing rust is high speed rotation of jet blade through high power motor, which makes steel sand, steel ball, iron wire, mineral and other abrasives to spray the surface of stainless steel pipe under the action of centrifugal force. It can not only completely remove rust, oxide and dirt, but also the stainless steel pipe is abrasive. Under the action of impact and friction force, uniform roughness can also be achieved. In the process of jet processing, the surface of the dry stainless steel pipe is also beneficial to the separation of steel balls, steel sand and rust and oxide skin, and the surface of the stainless steel pipe after rust removal is cleaner.
In the course of construction, the peeling strength of the corrosion resistant layer of the stainless steel pipe is obviously standard, and the quality of the corrosion resistant layer is guaranteed. On the basis of the same equipment, the process level is greatly enhanced and the production cost is reduced.
