How to Improve the Corrosion Resistance of Plate Flange?

  Plate Flange consists of a flange with a flange inner hole at the center of the flange and a plurality of screw holes on the plate flange. The screw holes are centrally symmetrical distributed with the center of the plate flange inner hole. On one side of the plate flange inner hole, there is an annular convex platform. The inner diameter of the annular convex platform is equal to the inner diameter of the plate flange inner hole, and the annular convex platform is equal to the inner diameter of the plate flange inner hole. The outer side is provided with an inclined plane with an inclination angle of 35 to 45 degrees from the plate flange. A sealing welding ring is arranged on the top of the ring convex platform. The inner diameter of the sealing welding ring is equal to the inner diameter of the ring convex platform, and the top surface of the sealing welding ring is provided with several welding grooves.

  A sealing welding ring is installed on the annular convex platform of the ASTM B16.5 WPB CL300 Stainless Steel Plate Flange. The sealing welding ring can be welded after the flat welding between the pipe and the plate flange. Thus, a complete sealing structure is formed between the pipe and the plate flange, and the external gas and liquid can not enter, which greatly improves the corrosion resistance of the plate flange.
