There are usually two methods of chemical and electrolytic pickling treatment, stainless steel pipeline corrosion protection only use chemical pickling, you can remove the oxide, rust, old coating, and sometimes this method can be used as a reprocessing after sandblasting rust. Although chemical cleaning can make the surface reach a certain degree of cleanliness and roughness, its anchor pattern is shallow, and it is easy to pollute the environment.
Jet removal of rust
Spraying (throwing) jet rust removal is driven by a high-power motor to spray (throwing) jet blade high-speed rotation, so that steel sand, steel balls, iron wire segments, minerals and other abrades under the action of centrifugal force on the surface of the steel pipe spraying (throwing) shooting treatment, not only can completely remove rust, oxides and dirt, but also stainless steel pipe in the abrasive impact and friction force under the action of The desired uniform roughness can also be achieved.
After spraying, not only can expand the physical adsorption of stainless steel pipe surface, but also can enhance the mechanical adhesion between the anticorrosive layer and the pipe surface. Therefore, spraying (throwing) jet rust removal is the ideal rust removal method for pipeline anticorrosion. Generally speaking, shot blasting (sand) rust removal is mainly used for the inner surface treatment of the pipe, and shot blasting (sand) rust removal is mainly used for the outer surface treatment of the pipe. Several problems should be paid attention to when using jet to remove rust.
