In order to clarify the significant parameters to control the deformability of high-grade induction bend pipes, finite element analyses simulating the deformation behavior subjected to an internal pressure and bending moment were carried out. Parametric studies were conducted using the finite element models with various mechanical properties and geometric imperfections. The change in the integrity of the buried pipeline due to the quality of the induction bend pipe was then quantitatively examined. Consequently, this study indicated that the mechanical properties, the dimensions and tolerance and the properties of the “transition” part should be appropriately designed in proportion to the ground deformation.
