Small Diameter Bright Seamless 316L Stainless steel MP(Mechanical Polishing) Tube

The methods for polishing stainless steel tubes mainly include mechanical polishing, electrolytic polishing, chemical polishing, ultrasonic polishing, and fluid polishing. Each of these methods has its own characteristics and applicable scenarios.

1. Stainless steel mechanical polishing pipe: Polish the surface and inner wall of the stainless steel tube by using a grinding wheel or a polishing wheel. For inner wall polishing, the grinding wheel needs to be placed in the tube and polished by high-speed rotation. If higher brightness is required, the polishing paste can be added during the polishing process. 12

2. Stainless steel electrolytic polishing pipe: The stainless steel tube is used as an anode and placed in an electrolytic cell. The tiny protrusions on the surface of the steel tube are dissolved by passing a direct current to achieve a smooth surface. After polishing, the surface oxide layer may be damaged and acid passivation treatment is required to prevent rust.

3. Stainless steel chemical polishing pipe: By immersing the stainless steel tube in the configured polishing liquid, the convex and concave parts of the steel tube surface are dissolved by a chemical process to achieve a smooth effect. This method does not require complex mechanical equipment, and multiple stainless steel tubes can be polished at the same time, which improves efficiency.

4. Stainless steel ultrasonic polishing pipe: The stainless steel tube is immersed in a grinding suspension and then placed in an ultrasonic field for polishing. This method will not cause the stainless steel pipe to deform, but it is more difficult to install. Now there is also a technology that combines ultrasonic and electrochemical methods. By adding ultrasonic vibrations while electrolyzing in a chemical solution, the substances on the surface of the stainless steel pipe can be separated faster.

5. Stainless steel fluid polishing pipe: Use fast-flowing liquid and abrasive particles to flow quickly on the surface of the stainless steel pipe to achieve polishing. The flowing liquid used in this method is usually a special substance with good fluidity, and the abrasive is usually silicon carbide powder.

Among the above methods, mechanical polishing is a commonly used method. If higher precision is required, electrolytic polishing may be used. The selection of a suitable polishing method depends on the specific requirements of the stainless steel pipe, the required surface quality, and the available equipment conditions.

MP(mechanical polishing) is a widely used surface treatment technology, polishing wheel or polishing belt with the abrasive polishing agent to polish the surface of stainless steel tubes, to promote the smooth polishing effect of stainless steel tube surface.

Its brightness and effect depend on the type of processing method. The effect of polishing depends on several factors, including the type of polishing wheel and polishing belt, the choice of polishing agent, polishing pressure and polishing time, etc. In addition, although mechanical polishing is more beautiful, it will also reduce corrosion resistance to a certain extent, so when used in a corrosive environment, it needs to be passivated, and the surface of the steel pipe often has residual polishing materials. This may be due to the abrasive in the polish not being completely removed, or due to glue or other residues on the polishing strip.

To solve this problem, cleaning and decontamination treatment can be carried out after polishing to ensure the clean and smooth surface of the steel pipe. The thickness of the steel pipe may be reduced during the polishing process, so precise control is required.
