Relevant knowledge of weld neck flanges

　　Weld neck flanges can be divided into free forging, upsetting, extrusion, die forging, closed die forging, closed upsetting.Weld neck flanges forging can be divided into free forging, upsetting, extrusion, die forging, closed die forging, closed upsetting. Closed die forging and closed upsetting have high material handling rate because there is no flash.

　　Finishing of weld neck flanges can be roughly completed by one or several processes. Because there is no flash, the force area of forgings will be eliminated, and the required load will also be eliminated. However, the blank should not be completely limited in detail. Therefore, the volume of the blank should be strictly controlled, the relative position of Customized Precision Forging Raised Face Weld Neck Flange should be controlled, and the wear of the forging die should be measured, so that the wear of the forging die can be eliminated happily.

　　According to the style of forging die, weld neck flanges can be divided into rotary forging, rotary forging, roll forging, cross wedge rolling, ring rolling and skew rolling. Rotary forging, rotary forging and ring forging can also be used for precision forging. Roll forging and cross rolling can be used as the preceding process to improve the material handling rate.

　　Torsional forging, like free forging, is also locally formed. Its benefits are compared with the size of forgings. Weld neck flanges can also be formed when the forging force is small. This forging style, including free forging, expands the material from all around the die surface to the free profile during processing, so it is difficult to guarantee the accuracy. Therefore, if the object of weld neck flanges and the rotary forging process are controlled by a computer, the products with huge shape and high precision can be obtained with lower forging force.
