Product Details



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

After spraying (throwing), the physical adsorption on the surface of the pipe can be expanded, and the mechanical adhesion between the anti-corrosion layer and the surface of the pipe can be enhanced.Therefore, spraying (throwing) jet derusting is the ideal derusting method of pipeline anticorrosion.Generally speaking, shot blasting (sand) derusting is mainly used for pipe internal surface treatment, shot blasting (sand) derusting is mainly used for pipe external surface treatment.Several problems should be paid attention to when using spraying (throwing) jet derusting.



For the United Spiraling Pipe for POSCO construction process of epoxy, ethylene, phenolic and other anticorrosive coatings commonly used in steel pipe, the surface of steel pipe is generally required to reach nearly white level (Sa2.5).It has been proved that almost all scale, rust and other dirt can be removed with this kind of derusting grade. The anchorage depth is up to 40~100 m, which fully meets the adhesion requirements of the anticorrosive coating and steel pipe, and the spraying (throwing) jet derusting process can meet the technical conditions of nearly white class (Sa2.5) with low operation cost and stable and reliable quality.
