The problems in the processing of stainless steel plate flange

　　1.weld defect: the weld defect of stainless steel plate flange is more serious. If it is made up by the manual grinding process, the grinding marks will cause the uneven surface, which will affect the beauty.

　　2.grinding and polishing passivation is uneven: manual grinding and polishing after pickling and passivation treatment, the larger area of the workpiece, it is difficult to achieve uniform and uniform treatment effect, can not get an ideal uniform surface. Besides, its disadvantages include man hour cost and excipient cost.

　　3.The scratch of DIN2576 Pn10 Stainless Steel plate flange is difficult to remove: overall pickling passivation, in the presence of corrosive medium in the presence of chemical corrosion or electrochemical corrosion and rust, and can not remove the scratch, welding spatter and adhesion on the stainless steel plate flange surface of carbon steel, spatter and other impurities;
