SS Sanitary Welded Seamless Tube with Low Price
Stainless steel sanitary pipes are mainly used in beverage, wine, bioengineering, food and other production equipment and lines. People mainly require the surface finish, passivation layer and oil resistance of stainless steel sanitary pipes:
1. Surface finish: Polish the inner and outer surfaces of the stainless steel sanitary pipe to make the surface of the steel pipe smoother and brighter, which is what we often call the mirror surface. The main purpose is to prevent the fluid material in the pipe from forming a hanging wall in the pipe, which is easy to contaminate and cause blockage in the pipe after a long time.
2. Passivation layer: After polishing, the steel pipe needs to be put into the passivation tank for immersion, and the surface of the steel pipe is oxidized with an acidic passivation solution to form a passivation layer to achieve the anti-corrosion effect of the steel pipe.
3. Oil-free degree…
