Industry applications of antibacterial stainless steel precision tubes after internal and external polishing

1. External polishing antibacterial Stainless Steel Precision Tube: most of the mechanical polishing process processing, the purpose is to improve the outer tube wall corrosion resistance, remove the surface oxidation, remove the scrapes generated during processing and improve the smoothness of the tube wall.

Electronic products tube shell: most of the requirements of the tube wall is 2B surface, that is, a kind of matte effect without brightness, wall roughness Ra0.4μm or so. This requirement of the pipe fittings basically no obvious oxide, rust, scratches, etc., the process requirements are not demanding, the cost is not high.

Bathroom mirror tube: many bathroom products manufacturers are choosing mirror effect antibacterial stainless steel pipe, we often say 8K mirror tube, roughness Ra0.1 ~ 0.2μm between. The surface gloss is very high, also accompanied by a high-grade fashion visual effect, due to the high surface precision requirements, the process cost will also increase.

2. Inner polished antibacterial stainless steel precision tube: This is a kind of antibacterial stainless steel tube with requirements for the smoothness of the inner wall, and the process difficulty of inner polishing is higher than outer polishing, and it is more difficult to control the quality when processing the inner wall, so the cost is also relatively high. In addition, antibacterial Stainless Steel Tube size is generally mechanical polishing method, the size of the specification is smaller generally used electrolytic polishing or electrochemical polishing method.

Food fluid tube for example: because in the process of use will be in direct contact with food, so the smoothness of the inner wall of antibacterial stainless steel is very important, if the antibacterial stainless steel tube wall is too rough will lead to scaling and blockage in the fluid tube. Antimicrobial stainless steel fluid tube requirements: wall roughness Ra ≤ 0.8μm, internal weld Rz ≤ 12.5μm, this standard reference "QB/T 2467-2017 stainless steel tube for the food industry". Antimicrobial stainless steel precision tube an antimicrobial stainless steel tube with more requirements for tube precision, the roughness of the inner and outer polish alone is also divided into more than a dozen standards; in addition, different types of tubes, their applications are different.
