Analysis and Simulation of the UOE Pipe Production Processing by Finite Element Method

摘要：

　　Large-diameter pipes used in offshore applications are commonly manufactured through the UOE process.The plate is crimped along its edges,formed into a U-shape and then pressed into an O-shape between two semicircular dies.The pipe is welded closed and then circumferentially expanded to obtain a highly circular shape.In this study,the two-dimensional finite element model of the whole processing of the UOE pipe production has been established,including large deformation and complex contact.The deformed geometries of different steps and distribution of the equivalent plastic strain and variation in load are analyzed.This research is helpful in UOE forming process design and evaluating the capability of the pipe mill.
