The phenomenon of diameter shrinkage in the beginning of expansion pipe occurred after expansion, which made it difficult to separate expansion cone from the expansion tube. The structure of the expansion tubular was improved to resolve the problem, and the finite element method(FEM) software ABAQUS was used to compute the expansion process. The expansion experiment showed that the phenomenon of diameter shrinkage disappeared and the expansion cone could fluently separate from the tube after expansion. So the optimized structure of the expansion tubular is significant to resolve the diameter shrinkage problem. The research achievement in this paper is important for the application of the expansion tubular. ©, 2015, Beijing Res. Inst. of Mechanical and Elec. Technology. All right reserved.
