The commonly produced stainless steel decorative pipe has a length of 6 meters. During production and transportation, the surface of the stainless steel pipe may be affected by lifting tools, production tools and the environment. When this phenomenon occurs, what impact will it have on stainless steel pipes?
After the stainless steel pipe is scratched, the surface protective layer is damaged, and the damaged surface is combined with air to oxidize, which will corrode for a long time and affect the service life of the stainless steel pipe.
So how to improve the service life and corrosion resistance of stainless steel pipes?
Regularly remove rust from stainless steel pipes. However, there are many reasons for corrosion of stainless steel pipes, and the treatment methods are also different.
One of the scratches on the surface of the stainless steel pipe is that the welder strikes the arc on the surface of the stainless steel pipe, which causes the protective film on the surface of the stainless steel pipe to be damaged, and the potential corrosive materials remain on it, resulting in damage to the stainless steel pipe.
In this case, the corrosive stainless steel pipe can be repaired by mechanical cleaning (solder spot polishing) or welding defects. In addition, rough surfaces of stainless steel pipes should be repaired or re-welded. The scratched part can clean the stainless steel pipe to prevent the product or process lubricating oil from being left in the scratches of the stainless steel pipe to corrode the surface of the stainless steel pipe.
