Food grade stainless steel tube

Food grade stainless steel tube is mainly used in food, beverage, wine, bioengineering and other production equipment and assembly line. It is mainly aimed at the surface finish, oil prohibition and passivation layer of stainless steel tube;

1. Surface finish: the internal and external surface of the steel pipe is polished to make the surface of the steel pipe bright; that is to say, the mirror surface. The main purpose is to prevent the fluid material from forming wall in the pipe, which is easy to pollute and form blockage after a long time.

2. Passivation layer: after polishing, the steel pipe should be immersed in the passivation pool, and the surface of the steel tube should be oxidized to form a passivation layer with acid passivation solution, so as to achieve the anti-corrosion effect of the steel tube.

3. Oil prohibition degree: after passivation, the oil prohibition cleaning shall be carried out to remove the oil stain on the steel pipe surface. After completion, it needs to be inspected by grease analyzer. It mainly prevents the oil pollution of the tube wall itself to the fluid substance in the tube.
