Those displacements cause large deformations of buried pipelines. Then, the knowledge of study and design recommendations related to deformability of the pipes has not been sufficiently provided. A grand number of studies have been reported concerned about the plastic deformations or buckling of the straight pipe. Most of them are performance of column pipe without internal pressure. Therefore, the purpose of this study is clarifying the deformations; steel pipes with internal pressure, axial compression and bending are analyzed. Effect of internal pressure on deformability of pipe is investigated both under compressive or load bending. Stress analysis using FEM is performed in order to simulate the large deformations of the pipes. Consequently, this research has focused on the behavior and study under seismic conditions, of already existing pipelines, located in high risk zones. The seismic actions induced a flexion pattern, causing deformations, strain, curvatures and ovalization along of the pipelines. This research describes in-plane bending the behavior in closing and opening mode to evaluate the response of the pipelines. The study involved a typical 20” internal diameter, API 5L X52 steel pipeline.
