Spiral steel pipe is widely used in agriculture, chemical industry, construction, water conservancy engineering, petrochemical industry, and other industries, can be used for liquid transport, gas transport, building structures. In daily use, due to management or improper use often lead to spiral pipe corrosion, shorten the service life. Therefore, it is necessary to master the advanced rust removal technology of spiral welded pipe, so as to avoid the rust of steel products and minimize the loss caused by the rust of spiral steel pipe. There are several methods to remove rust from the surface of the spiral steel tube:

1. Rust removal of tools first use a steel wire brush and other tools to polish the appearance of steel can remove loose or warped oxide, rust, welding slag and so on. Manual tool derusting can reach Sa2 level, power tool derusting can reach Sa3 level if the steel surface adheres to a strong scale, tool derusting results are not ideal, not up to the anti-corrosion construction requirements of anchor depth.

2, picklingCommon chemical and electrolytic pickling treatment, pipeline corrosion only using chemical pickling, can remove the scale, rust, old coating, sometimes used as sandblasting after the treatment of rust. Chemical cleaning is able to make the appearance of inevitable cleanliness and roughness, but its shallow anchorage, and easy to form pollution of the situation.

3. Spray (toss) jet derustingSpray shot derusting (cast) is a high power motor drive spray (cast) blade high-speed twist, make steel shot, steel grit, wire section, minerals and other abrasive under the centrifugal force effect on steel tube appearance spray (cast) disposal, not only can completely eliminate rust, oxides and dirt, and the effect of steel tube in the fierce impact and friction abrasive, can reach the requirements of course degree on average.

After spraying (throwing), the physical adsorption effect on the surface of the pipe can be expanded, and the mechanical adhesion effect between the anti-corrosion layer and the surface of the pipe can be enhanced. Therefore, spraying (throwing) jet derusting is the ideal derusting method for pipeline anticorrosion. Generally speaking, shot peening (sand) derusting is primarily used for pipe internal surface treatment and shot blasting (sand) derusting is primarily used for pipe surface treatment.
