Introducing The Fine Polishing Effect And Method Of Stainless Steel Pipe Elbows

Stainless Steel Weld Elbow connection, anti-vibration, make the connection part at one time, avoid the possibility of loosening of the "live joint", convenient construction, avoid on-site welding and threading operations, and the service life of the stainless steel elbow is good. Field corrosion test data show that the service life of stainless steel elbows can reach 100 years, and stainless steel elbows require almost no maintenance. Therefore, its performance-price ratio is good, the operating life cost is low, and the economic benefits are obvious.

The polishing machine used for fine polishing of stainless steel elbows is basically the same as the equipment used for rough polishing, and its speed is 150-200 rpm. Fine polishing uses soft wool fabric, usually fine woolen cloth for polishing. The polishing powder should be finer, and the chromium oxide sold on the market can be used for fine polishing after water selection and floating. If you want the best polishing effect, you can use fine magnesium oxide or aluminum oxide as a polishing liquid for manual polishing on suede. The pressure applied during fine polishing should be lighter than that during rough polishing, the polishing liquid should not be too thick, and the velvet plate should maintain the humidity. If the wool is too dry, the grinding surface will be easily scratched, resulting in deeper scratches. If the wool is too wet, it will also oxidize the grinding surface. The humidity of the wool will gradually decrease as the polishing process progresses. Observe the fine polishing of the sample frequently. After picking up the sample, there will be no polishing liquid or small water droplets on the polished surface. Polish gently while maintaining a water film that dries as soon as it is blown. When the scratches from the rough polishing of the sample disappear, the matrix is ​​clear, and there is no water film on the polished surface of the sample after picking it up, the fine polishing of the sample is appropriate. If magnesium oxide polishing powder is used, it should be prepared as it is used. After use, the wool plate should be removed and carefully cleaned in running water to prevent deterioration. During the polishing process, the sample should not be polished for too long or under too much pressure, whether it is rough polishing or fine polishing. Otherwise, the phases in the alloy will be thrown away, and the deformation layer of the grinding surface will be deepened, thereby affecting the polishing quality and drawing wrong organizational conclusions in the next observation.
