In-home decoration, kitchens and bathrooms are places where thin-walled stainless steel water pipes play a role. There are more and more types of stainless steel water pipes, however, the quality is different. There are many defects in thin-walled stainless steel water pipes. So what caused the surface defects of these water pipes?
Reasons for surface defects of thin-walled stainless steel water pipes:
1. Uneven polishing and passivation
Pickling passivation treatment is carried out after manual polishing, especially for blunt parts with a large area, it is difficult to achieve a uniform effect, and an ideal uniform surface cannot be achieved.
2. Inadequate pickling
It is difficult for pickling passivation to remove the black oxide scale caused by plasma cutting and flame cutting.
3. Scratches caused by human factors
In the process of hoisting, transportation and processing, bumping, dragging, hammering, etc. can damage the thin-walled stainless steel water pipe, which is also the main reason for the defects on the surface of the water pipe.
