Increase The Durability Of Spiral Steel Pipes

Spiral steel pipe manufacturers have good anti-corrosion performance for the anti-corrosion spiral pipe produced by them, and in order to improve the service life of the anti-corrosion spiral pipe, appropriate surface treatment should be carried out. The surface treatment of spiral steel pipe is beneficial to improve its service life. The following describes the surface treatment method of the anticorrosive spiral tube:

1. The surface of the anticorrosive spiral tube cleaned with solvent and emulsion, so that the organic matter on the surface of the spiral tube can be removed, but it cannot remove the surface rust, scale, flux, etc., so the cleaning can only be used as an auxiliary means.

2. Use the wire brush, sandpaper and other tools to polish the surface of the anti-corrosion spiral tube to remove loose oxide scale, rust, welding slag and so on.

3. Pipe anti-corrosion uses chemical pickling, which can remove scale, rust and old coating, and can achieve a certain degree of cleanliness and roughness.

4. High-speed motor drives the high-speed rotation of the sprayed (spraying) blades, so that the abrasives such as steel grit, steel shot, wire segment and minerals can be sprayed (throwed) on the surface of the anti-corrosion steel pipe under the action 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 action of abrasive violent impact and friction.
