Benefits of pickling of nickel-based alloy pipes
Pickling surface treatment methods of nickel-based alloy pipes
Generally, there are two methods for pickling: chemical and electrolytic. For stainless steel pipe anti-corrosion, only chemical pickling is used, which can remove scale, rust, and old plating. Sometimes this method can also be used as a re-treatment after sandblasting. 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 cause pollution to the environment.
Spraying (blasting) rust removal
Spraying (blasting) rust removal is to use a high-power motor to drive the spray (blasting) blade to run at a high speed, so that steel sand, steel balls, wire segments, minerals and other abrasives are sprayed (blasted) on the surface of the steel pipe under the action of centrifugal force. It can not only remove rust, oxides and dirt, but also the stainless steel pipe can achieve the required uniform roughness under the strong impact and friction of the abrasive.
After spraying (blasting) rust removal, it can not only expand the physical adsorption effect on the surface of the stainless steel pipe, but also enhance the mechanical adhesion between the anti-corrosion layer and the pipe surface. Therefore, blasting (blasting) rust removal is an ideal rust removal method for steel pipe anti-corrosion. Generally speaking, shot blasting (sand) rust removal is mainly used for pipe inner surface treatment, and shot blasting (sand) rust removal is mainly used for pipe outer surface treatment. Several issues should be noted when using blasting (blasting) rust removal.
