Straight seam steel pipe in addition to embroidery methods are mainly the following:
1, cleaning -
Solvents and emulsions are used to clean steel surfaces to remove oil, grease, dust, lubricants, and similar organics. However, they cannot remove rust, oxide scales, and soldering flux on the surface of steel materials. Therefore, they are used only as an aid in anti-government operations.
2, pickling -
General use of chemical and electrolytic methods for pickling, pipe anti-corrosion chemical pickling only, can remove oxide scale, rust, old coating, and sometimes can be used as a blasting rust after reprocessing. Although chemical cleaning can achieve a certain degree of cleanliness and roughness on the surface, its anchorage pattern is shallow and it is easy to pollute the surrounding environment.
3, tool rust -
The main use of wire brush and other tools on the surface of the steel, can remove loose oxide, rust, welding slag and so on. The manual tool derusting can reach Sa2 level, and the derusting of power tools can reach Sa3 level. If the steel plate surface is attached with a solid iron oxide scale, the rust removal effect of the tool is not satisfactory, and the depth of the anchoring lines required for anti-corrosion construction cannot be achieved.
4, spray rust -
Jet rust removal is driven by a high-power motor to drive the high-speed rotation of the jetting blade, so that abrasive particles such as steel shot, steel grit, wire segment, and minerals are sprayed on the surface of the straight seam steel pipe under the powerful centrifugal force of the motor. , rust and dirt, and straight seam steel pipe in the abrasive impact and friction force, but also to achieve the required uniform roughness.
After rust removal by spraying, not only can the physical adsorption of the pipe surface be enlarged, but also the mechanical adhesion of the corrosion protection layer to the surface of the pipe can be enhanced. Therefore, spray rust removal is an ideal rust removal method for pipeline anti-corrosion. In general, shot rust removal is mainly used for inner surface treatment of tubes. Shot blasting is mainly used for outer surface treatment of straight seam steel tubes. During the production process, relevant technical indicators for rust removal must be strictly required to prevent accidental damage to the straight seam steel pipe. Straight seam steel pipe is subjected to the de-embroidering process. The appearance of the straight seam steel pipe will be smoother than that before the embroidering, and the straight seam steel pipe will be removed. Embroidering in the steel pipe industry is a frequently used technology.
