Sanitary stainless steel pipes also belong to the category of stainless steel pipes, but the requirements for sanitary steel pipes are more stringent than ordinary stainless steel pipes.
First of all, the requirements for surface finish: the inner and outer surfaces of the steel pipe are polished so that the surface of the steel pipe is flat; that is, what we often call a mirror surface. The main purpose is to prevent the fluid material going in the tube from forming a wall in the tube, which will easily pollute and cause blockage in the tube after a long time.
Secondly, the requirements for the passivation layer: After the polishing is completed, the steel pipe needs to be immersed in a passivation pool, and the surface of the steel pipe is oxidized with an acidic passivation solution to form a passivation layer to achieve the corrosion resistance of the steel pipe. In addition, there are certain requirements for the degree of oil prohibition: after the passivation is completed, carry out oil prohibition cleaning to remove the oil stains on the surface of the steel pipe. After completion, it needs to be checked with a grease analyzer. It is mainly to prevent the oil pollution of the pipe wall itself from contaminating the fluid substances in the pipe. The difference between sanitary stainless steel pipes and ordinary stainless steel pipes Compared with ordinary stainless steel pipes, the main difference of sanitary stainless steel pipes is that the inner surface is polished, which reduces resistance and increases fluidity when transporting fluids, making the fluids stainless and mixed. The debris on the pipe wall peeled off by the impact of the fluid also makes the inner wall of the steel pipe less prone to fouling and ensures hygiene.
