  According to the principle of deformation during welding of large threaded flange, the influence of welding skill on transverse shortening is analyzed by using low carbon steel and full specification stainless steel. The welding method of selecting section back welding, adding short section or selecting upper thin and lower thick ANSI B16.5 Class 600 Stainless Steel Threaded Flange is put forward. Add sealing points between two threaded flange, and then fasten them with bolts. The first standards are national standards, electric standards, American standards, German standards, Japanese standards, etc.

  Attention should be paid to improving the working environment of hot forging. Always adhere to the dryness and ventilation of stainless steel large threaded flange, adhere to the cleaning and tidiness of the device, and store it in accordance with the correct storage method. The value in brackets indicates the allowable wall thickness error value of the same large threaded flange on different sections. The distance between the two sections is not more than twice the pipe diameter, and the maximum is not more than 300 mm.

  Forged large threaded flange connection is easy to use and can bear large pressure. Butt welding is adopted for the connection of large threaded flange and pipeline. The welding seam is similar to the welding of pipeline and pipeline. Generally, argon arc welding is adopted for the small pipe diameter, and double-sided welding is adopted for the large pipe diameter.
