What should I do if the precision tube is rusted and the color is not good?

Use solvents and emulsions to clean the surface of precision pipes to remove oil, grease, dust, lubricants and similar organic matter, but it cannot remove rust, oxide scale, welding flux, etc. on the surface of precision pipes, so it is only used as an auxiliary in anti-corrosion production means.

2.tool rust removal

Mainly use tools such as wire brushes to polish the surface of precision pipes, which can remove loose or warped oxide scale, rust, welding slag, etc. The rust removal of hand tools can reach Sa2 level, and the rust removal of power tools can reach Sa3 level. If the surface of the precision pipe is attached with firm oxide scale, the tool rust removal effect is not ideal, and the anchor pattern depth required for anti-corrosion construction cannot be reached.


Generally, two methods of chemical and electrolysis are used for pickling treatment. Pipeline anticorrosion only uses chemical pickling, which can remove oxide scale, rust, and old coating. Sometimes it can be used as a reprocessing after sandblasting and rust removal. Although chemical cleaning can make the surface reach a certain degree of cleanliness and roughness, its anchor pattern is shallow and it is easy to pollute the environment.

Tips:ASTM A53 seamless and welded steel pipe is a general, all-purpose pipe used in generator plants, refineries, compressor stations, natural gas transmission, and steam conduction. It is acceptable for welding, flanging, and bending.
