Product Details



used spiral weld steel pipe The raw material of spiral steel pipe is steel plate, if it is not treated, it will rust.The anticorrosion of steel pipe is a key link in the production and application of steel pipe.In order to achieve the ideal rust removal effect, the abrasive should be selected according to the hardness of the steel tube surface, the degree of original corrosion, the required surface roughness, coating type, etc. For the single layer of epoxy, two or three layers of polyethylene coating, the mixed abrasive of steel sand and steel shot is easier to achieve the ideal rust removal effect.

The steel shot has the function of strengthening the steel surface, while the steel sand has the function of etching the steel surface.During the production process, relevant technical indicators of rust removal should be strictly required to prevent secondary damage to straight seam steel pipes caused by operational errors. Straight seam steel pipes will be smoother after embroidery removal, and the appearance of products will be smoother than before embroidery removal. The embroidery removal of straight seam steel pipes is a frequently used technology in the steel pipe industry.



Jet derusting is an ideal method for pipeline corrosion control.Generally speaking, shot peening and derusting are mainly used for inner surface treatment of pipes, while shot blasting and derusting are mainly used for outer surface treatment of straight welded steel pipes.Spray derusting is driven by high-power motor jet high-speed rotating blade, steel shot, steel grit, wire section, minerals and other abrasive in motor power under the action of centrifugal force of the straight seam steel pipe surface spray processing, not only can thoroughly remove oxide, 



rust and dirt, and straight seam steel pipe under the action of abrasive violent impact and friction, also can achieve the required uniform roughness.After spraying and derusting, not only the physical adsorption on the surface of the pipe can be expanded, but also the mechanical adhesion between the anti-corrosion layer and the surface of the pipe can be enhanced.No matter what method is used to remove rust, our goal is to extend the life of steel pipes and make the users get value for money. Now what we should do is to constantly improve the surface treatment method of straight seam steel pipes and try to find the most convenient, time-saving and low-cost method.
