Polishing method of stainless steel pipe

1. Mechanical polishing
   Mechanical polishing not only polishes the surface and inner wall of stainless steel pipes. When polishing the inner wall of the steel pipe, you need to put the grinding wheel into the steel pipe and polish the inside of the steel pipe through high-speed rotation. If you feel that the stainless steel pipe is not bright enough, you can also add polishing paste during the polishing process, which can improve the brightness of the steel pipe.
   Mechanical polishing can remove a thin metal layer on the surface of the stainless steel pipe. If there are very deep wear marks on the surface of the steel pipe, it will be difficult to remove the wear marks on the steel pipe only by mechanical polishing. When polishing, you also need to add concentrated polishing fluid and apply appropriate pressure. These operations will increase the polishing time.

2.Electrolytic polishing
   To polish in this way, you need to first place the steel pipe in an electrolytic tank, where the anode is a stainless steel pipe and the cathode is an insoluble metal. After the electrolytic cell is supplied with direct current, the tiny protrusions on the surface of the stainless steel pipe can be dissolved, making the surface smoother.

3.Chemical polishing
Place the stainless steel pipe in the prepared polishing fluid to dissolve the convex or concave parts on the surface of the steel pipe, making the surface of the steel pipe smoother. This polishing method does not require complex mechanical equipment. It only needs to configure the polishing fluid to polish multiple stainless steel pipes at the same time, which is more efficient.

4. Ultrasonic polishing
   Soak the stainless steel pipe into the grinding suspension in advance, and then put it into the ultrasonic field together. The stainless steel surface is polished through the back and forth vibration of ultrasonic waves. Polishing using this method will not cause the stainless steel pipe to deform, but it is very difficult to install. Now, ultrasonic and electrochemical methods are combined, and the stainless steel pipe is placed in a chemical solution. During electrolysis, ultrasonic waves are added to oscillate back and forth to speed up the separation of materials on the surface of the stainless steel pipe.

5. Fluid polishing
   This method mainly uses fast-flowing liquid and abrasive particles to flow quickly on the surface of the stainless steel pipe to achieve polishing effect. The flowing liquid used is a special substance with good fluidity, and the abrasive is silicon carbide powder that is more common in processing.
