Abstract
Ovality is one of the important quality parameters of pipes. If ovality does not meet the standard, the performance and life of pipes will be affected. In order to improve the quality of pipe connections, ovality of pipe ends has higher requirements. Since existing processes cannot achieve continuous and high-efficiency setting-round of pipe ends, this study proposed a three-roller setting-round process for pipe ends. Experiments and numerical simulations were performed to verify the feasibility of the process. In simulations, the Bauschinger effect, the variation of chord modulus, and the yield plateau phenomenon were considered. The results show that residual ovality of the straight pipes, elbow, and tee pipe after setting-round is less than 1%, which is in line with the API standard. Residual ovality of pipe ends decreases with the increase of the reduction, and tends to be stable after reaching the optimum reduction. There is an approximate linear relationship between the relative thickness and the optimal reduction. With the increase of the relative thickness, the optimal reduction shows a downward trend. The proposed process can realize continuous setting-round of pipe ends of straight pipes, elbows, and tee pipes, and improve the setting-round efficiency. In addition, the setting of process parameters is independent of initial ovality, and the process is simple to realize.
