Key points of fine steel pipe derusting skill

Release time: September 19, 2020 popularity: one

   The key technology of fine steel pipe derusting is to use solvent and emulsion to clean the steel surface to remove oil, grease, dust, lubricant and similar organic matter, but it can not remove the rust, oxide skin and welding flux on the steel surface, so it can only be used as an auxiliary method in government operation.




    Generally, chemical and electrolytic methods are used for acid pickling. Chemical pickling is only used for pipeline anti-corrosion, which can remove oxide scale, rust and old coating. Sometimes it can be used as the re-treatment after sand blasting. Although chemical cleaning can make the surface reach a certain degree of cleanliness and roughness, but its anchor lines are shallow, and a brief pollution to the surrounding environment.

    East and West rust removal mainly uses wire brush and other things to polish the steel surface, which can remove loose oxide skin, rust, welding slag, etc. Manual East-West rust removal can reach SA2 level, and dynamic East-West rust removal can reach SA3 level. If the steel surface is attached with strong oxide scale, the effect of East-West rust removal is not interesting, and the anchor depth required by anti-corrosion construction can not be reached.

    Eruption derusting is to use high-power motor to drive the eruption blade to rotate at high speed, so that steel balls, steel sand, iron wire sections, minerals and other abrasives can be sprayed on the surface of fine steel pipes under the strong centrifugal force of the motor. It can not only completely remove oxides, rust and dirt, but also under the effect of severe impact and friction force of abrasive, It can also achieve the required uniform roughness.
