ANSI DIN EN BS JIS ISO Forged Steel Weld Flange Stainless Steel Flange
Flange is a common mechanical industrial product, which is also called flange flange plate. Flanges are the parts connecting pipes and pipes, which are used for the connection between pipe ends; The flange on the inlet and outlet of the equipment is also used for the connection between two equipment. So it is also called fastener.
There are two kinds of forging processes for the neck butt welding flange:
1: Die forging; Namely, the steel raw material is heated to 1200 C in the heating furnace, and then put into the mold of corresponding specifications for forging. For 2 "- 10" (DN50-DN250), the inner hole shall be punched with a specific punch.
2: It is free forging. Heat up the raw material in the heating furnace to 1200C, then forge the square material into a round cake shape, punch the hole, and use special equipment (roller and horse frame) to expand the hole of the punched raw material to the required size. Suitable for specifications above (DN300-DN3000).
