Ordinary honed carbon seamless steel tubes are basically not resistant to corrosion. If there is no good storage site but placed outdoors or in a humid environment, honed carbon seamless steel tubes will rust, which requires rust removal.
Several methods of derusting honed carbon seamless steel tube:
The first way: pickling
Generally, chemical and electrolytic methods are used for pickling treatment. Only chemical pickling is used for pipeline anticorrosion, which can remove scale, rust, and old coatings. Sometimes it can be used as retreatment after sandblasting and rust removal. Although chemical cleaning can achieve a certain degree of cleanliness and roughness on the surface, its anchor pattern is shallow and it is easy to pollute the environment.
Two: cleaning
Use solvents and emulsions to clean the surface of honed carbon seamless steel tubes to remove oil, grease, dust, lubricants and similar organic substances, but it cannot remove rust, scale, welding flux, etc. on the steel surface, so in anti-corrosion production As an aid only.
Three: tool derusting
Mainly use tools such as wire brushes to polish the surface of honed carbon seamless steel tubes, which can remove loose or raised scale, rust, welding slag, etc. If the iron oxide scale is firmly attached to the surface of the steel, the derusting effect of the tool will not be ideal, and the anchor pattern depth required for anti-corrosion construction will not be reached.
