How to remove rust from straight seam steel pipes?
Straight seam steel pipes are made of high-quality steel, but steel-like metals will still rust if they are exposed to the air for a long time. Straight seam steel pipes are often used in oil and gas pipeline construction. The anti-rust treatment on their surfaces will directly affect the use effect and service life of straight seam steel pipes. So how to treat the surface of straight seam steel pipe? How to remove rust? List the following methods for removing rust from straight seam steel pipes and see which one is more suitable for you.
1. Straight seam steel pipe cleaning method
Using chemical substances such as emulsions or emulsions to clean the surface of the straight-seam steel pipe can remove dust, grease and other surface contaminants on the straight-seam steel pipe. The cleaning method is only an auxiliary and preventive function, and cannot really remove the flux, rust and oxide scale of the straight seam steel pipe.
2. Straight seam steel pipe pickling method
Using acidic chemical reagents to rinse the rust of straight-seam steel pipes can clean the surface and remove rust and scale. However, the use of pickling will cause pollution to the ecological environment and exceed national environmental protection indicators. Improper use will also damage the straight seams. Steel pipes affect the use, so this method has been cancelled.
3. Straight seam steel pipe tool rust removal method
Using tools such as wire brushes to polish the surface of straight seam steel pipes can remove superficial rust, welding slag and oxide scale, but deep and strong rust cannot be completely removed and construction requirements cannot be met.
4. Straight seam steel pipe spraying method
The motor is used to drive steel sand, steel balls, wire segments and other abrasives to rotate at high speed, and the oxides and rust on the surface of the straight-seam steel pipe are rubbed away under the action of centrifugal force, and the roughness of the straight-seam steel pipe is ensured to be uniform, and the adhesion of the surface of the straight-seam steel pipe is improved. It will not damage straight seam steel pipes.
