How to improve the durability of spiral steel pipes

spiral steel pipes require exterior treatment to add durability.

1.using solvent and emulsion to clean the surface of the anti-corrosive spiral tube. this can remove the organic material on the surface of the spiral tube, but it cannot remove the surface rust, scale, solder, etc. therefore, cleaning can only be used as an auxiliary means.

2.using wire brushes, sandpaper, etc. to polish the surface of the anti-corrosion spiral tube, which can remove loose oxide scale, rust, welding slag, etc.

3.pipeline anticorrosion is selected by chemical pickling, which can remove scale, rust and old coatings, and can achieve a certain degree of cleanliness and roughness.

4.the high-speed motor drives the spray (projection) blades to rotate at high speed, so that abrasives such as steel grit, steel shots, wire segments, and minerals can be sprayed (projected) on the surface of anti-corrosive steel under the effect of centrifugal force, which can not only completely remove rust, oxides and dirt, and the anti-corrosion steel pipe can achieve the required uniform roughness under the effect of the strong impact and friction of the abrasive.
