In order to ensure a smooth and beautiful surface, ASTM B729 UNS N08020 Duplex Stainless Steel Pipe is often polished. With the continuous innovation of the production process, several polishing methods have appeared, but each polishing method has its own Advantages and disadvantages and use environment, today we will introduce some of the more commonly used polishing distribution.
1. Mechanical polishing
The advantage of this polishing method is that after polishing, the overall flatness is relatively good, and the surface gloss is high, but it also has obvious disadvantages, that is, the labor intensity is relatively high, and it will cause great pollution to the environment, and the product surface The gloss lasts for a relatively short time, and it is prone to dullness and rust.
2. Chemical polishing
The more prominent advantages of this polishing method are that the equipment is relatively simple, the investment is low, the polishing speed is fast, the processing efficiency is high, and it has good corrosion resistance, but its disadvantage is that the gloss is relatively poor, and the processing The process has high requirements on the environment, and requires it to be used in an open and ventilated environment.
3. Electrochemical polishing
The advantages of this polishing method are that the process is stable, the surface gloss is maintained for a long time, and the pollution to the environment is relatively small. Its disadvantage is that it needs to invest a lot of money in production equipment, and it also needs to be equipped with cooling equipment during the production process. However, it is suitable for mass production.
The above are three commonly used ASTM B729 UNS N08020 Duplex Stainless Steel Pipe polishing methods. Have you learned it after reading it? However, in practical applications, it is very important to choose the appropriate polishing method for different needs.
