One type of Xi'an stainless steel pipe is called sanitary stainless steel pipe, which is mainly used in food, beverage, wine, biological engineering and other production equipment and assembly lines.

Sanitary stainless steel pipes are mainly required for the surface finish, oil tolerance and passivation layer of Xi'an stainless steel pipes;

1. Surface finish: Polish the inner and outer surfaces of the steel pipe to make the surface of the steel pipe bright; that is, the mirror surface we often say. The main purpose is to prevent the fluid substance in the tube from forming a hanging wall in the tube, which is prone to pollution and clogging in the tube over time.

2. Passivation layer: After the polishing is completed, the steel pipe needs to be immersed in the passivation tank, 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 forbidden degree: After the passivation is completed, oil forbidden cleaning is performed to remove the oil stain on the surface of Xi'an stainless steel pipe. After the completion of the inspection with a grease analyzer. The main purpose is to prevent the oil contamination of the pipe wall from contaminating the fluid substances that go inside the pipe.
