Spiral steel pipe surface rust removal treatment has several met
Views: 121 Update Date: Nov 23 , 2022
1、Cleaning
Apply solvents and emulsions to clean the exterior of steel to remove oil, grease, dust, slicker and similar organic substances, but it cannot remove rust, oxidation skin, welding powder, etc. on the exterior of steel, so it is only used as an auxiliary trick in anti-corrosion production.
2、Spraying (throwing) rust removal
Spraying (throwing) rust removal is driven by a high-powered motor spraying (throwing) injection blade twisting at high speed, so that steel sand, steel shot, wire segments, minerals and other abrasives in the effect of centrifugal force on the steel pipe exterior spraying (throwing) injection disposal, not only can completely purge rust, oxides and dirt, and steel pipe in the abrasive fierce impact and the effect of friction, but also to reach the required average roughness.
After spraying (throwing) rust removal, not only can extend the physical adsorption effect of the tube exterior, but also can strengthen the mechanical adhesion effect between the anti-corrosion layer and the tube exterior. Therefore, spray (shot) descaling is the ideal descaling method for pipeline corrosion protection. Generally speaking, shot (sand) descaling* is to be used for pipe inner appearance disposal, and shot (sand) descaling* is to be used for pipe surface face disposal.

3, tool rust removal
To use tools such as wire brushes to polish the steel exterior, which can remove loose or buckled oxide, rust, weld slag, etc. Hand tool rust removal can reach Sa2 level, power tool rust removal can reach Sa3 level, if the steel appearance attached to the solid iron oxide skin, tool rust removal results are not ideal, not up to the depth of the anchor pattern required for anti-corrosion construction.
4、Acid washing
Commonly, two methods of pickling disposal are used: chemical and electrolytic. Pipeline anti-corrosion only uses chemical pickling, which can remove oxidized skin, rust and old coating, and sometimes it can be used as re-disposal after sandblasting rust removal. Chemical cleaning can certainly make the appearance to a certain degree of cleanliness and roughness, but its anchor pattern shallow, and easy to form pollution to the situation.
