Abstract

Under internal high pressure, the stress of the intrados of the elbow is higher than that of the extrados, so the extrados single-welded elbow can withstand greater internal pressure than the intrados single-welded elbow. In this paper, a novel cold stamping process of extrados single-welded elbow is proposed. It mainly includes blanking, U-forming, O-forming, welding, and cutting excess material, which is especially suitable for the production of large thin-walled pipeline elbows. The initial blank shape and size of the 90° elbow with extrados single welded are obtained by the one-step formability analysis of DYNAFORM. The stamping process of the elbow is simulated by ABAQUS. The die structure is designed, and the forming defects such as wrinkling and lack of material are overcome. When the compression ratio is 0.75% during O-forming, the ovality of the central plane and end face of the elbow reach 0.55% and 0.69%, respectively. The maximum thickening rate and thinning rate of the formed elbow are 8.8% and 12%, respectively. All geometric parameters of the elbow meet the API 5L standard.
