Experimental study of roll forming of weld neck flanges
A roll forming situation of a weld neck flange is introduced. Through the test rolling of several flange blanks, it is concluded that the flange is challenging to roll forming. Still, it provides a solid basis for the combination of casting and rolling creating to improve the quality of the flange. The method can be used as a reference for the new process of manufacturing weld neck flanges. Flanges are widely used as pipe coupling parts. The flange is generally produced by casting molding or forging punching. Casting flange internal organization is loose and uneven, strength and quality are difficult […]
