How to polish thin wall brass tube?As a high-quality tube, thin-walled brass tube is widely used in the fields of electronics, electrical appliances, refrigeration, HVAC and so on due to its good electrical conductivity, thermal conductivity and plasticity. However, it is of great significance to polish the thin-walled brass tubes because the roughness and oxide film on its surface will affect the connection, welding and appearance of the tubes. This paper will discuss the importance and methods around the thin-walled brass tube polishing.

First, the importance of brass tube polishing

  1. Improve the surface finish of the tube: polishing treatment can remove the oxide film on the surface of the thin-walled brass tube, scratches and other defects, so that the surface finish of the tube is improved, which is conducive to the subsequent processing and connection.
  2. improve electrical and thermal conductivity: polishing treatment can remove the oxide film on the surface of the tube, reduce the resistance, improve electrical and thermal conductivity, is conducive to improving the performance of the product.
  3. Improve welding quality: Polishing treatment can remove the oxide film on the surface of the pipe, oil and other impurities, which is conducive to the formation of the molten pool in the welding process and improve the welding quality.
  4. Enhance corrosion resistance: Polishing treatment can make the pipe surface smoother and reduce the microscopic defects on the pipe surface, thus improving the corrosion resistance.
  5. Improve the appearance of the product: after polishing the surface of the thin-walled brass tube is smooth, beautiful, conducive to improving the appearance of the product quality.

Second, thin-walled brass tube polishing methods to discuss

  1. Mechanical polishing: mechanical polishing refers to the use of polishing machines, sandpaper and other tools on the surface of thin-walled brass tube grinding, polishing. The method is simple to operate, but the polishing effect is affected by the operator’s skills and equipment performance, and there is some damage to the surface of the pipe.
  2. chemical polishing: chemical polishing refers to the thin-walled brass tube into the chemical polishing solution, through the chemical reaction to remove the oxide film on the surface of the tube and other impurities. The method of polishing effect is good, but there is a certain amount of pollution to the environment, and the cost is high.
  3. Electrochemical polishing: electrochemical polishing refers to the electrolyte solution, through the role of the current to remove the oxide film on the surface of thin-walled brass tube. The method of polishing effect is good, suitable for mass production, but the equipment requirements are high.
  4. Laser polishing: laser polishing refers to the use of laser beams on the surface of thin-walled brass tube irradiation, through the laser energy to remove the oxide film and other impurities. The method of polishing effect is good, suitable for high-precision requirements of the occasion, but the equipment cost is higher.

In summary, thin-walled brass tube polishing treatment is of great significance, which can improve the performance, appearance quality and service life of the tube. In the actual production process, the appropriate polishing method should be selected according to the specific conditions. At the same time, strengthening the research and improvement of polishing technology can help improve the competitiveness of China’s thin-walled brass tube industry.
