How to solve the problems that occur in the process of processing stainless steel flanges? best steel plate flange- GKSTEELPIPE The processing of stainless steel flanges needs to understand and pay attention to some problems: 1. Welding seam defects: the welding seam defects of stainless steel flanges are more serious. If manual mechanical grinding is used to make up for it, the grinding marks produced will cause uneven surface and affect the appearance; 2. Uneven grinding and polishing passivation: pickling passivation after manual grinding and polishing, it is difficult to achieve a uniform treatment effect for a workpiece with a large area, and an ideal uniform surface cannot be obtained. There are also its shortcomings in terms of labor costs and high cost of auxiliary materials; 3. Scratches are difficult to remove: the overall pickling passivation, chemical corrosion or electrochemical corrosion and rust will occur in the presence of corrosive media, and carbon steel
