Surface rust removal treatment method for stainless steel special-shaped pipes

1. Surface rust removal treatment of stainless steel special-shaped pipes. The surface of the rusty steel is tilted, scaled and welded slag, and the rust removal method can be used to clean the surface of the tool, that is, grinding the wire brush tool, but if the oxide scale on the steel surface is fixed, the rust removal effect is not ideal because of the power tool cleaning Hand tool rust removal can reach level 3 and reach Sa2 level, so the choice of rust removal method is based on the actual situation.

2. Surface emulsification treatment of stainless steel special-shaped pipes. The use of emulsification and solvent for surface cleaning of stainless steel special-shaped pipes is only used as an auxiliary method for corrosion production, because it cannot remove oxide scale, flux and rust on the surface of the pipe, but it can clean the steel, remove grease, a class of organic compounds, and lubricate the surface oil and dust.

3. The surface of stainless steel special-shaped pipes is pickled. Pickling methods include electrolysis and chemical methods. Chemical methods can not only remove rust, scale and coating on the surface of stainless steel special-shaped pipes, and this method is used after sandblasting and rust removal. However, this method is flawed. Cleaning the anchor is lightweight and can easily cause pollution to the environment.

4. The surface of stainless steel special-shaped pipes is sprayed and rust-removed. Jet rust removal can not only completely remove oxides, rust, and friction and impact forces on the surface of stainless steel special-shaped pipes, but also achieve the required uniform surface roughness when used with abrasives and steel pipes.
