pages 173 - 176, full text

The research involved the performance of a strength analysis of a linear expansion joint of a large internal diameter, used in gas pipelines. Such devices aim to absorb and compensate multi-directional displacements caused by geological activity of the ground or climate conditions. The work involved the development of a numerical model of the expansion joint using the Ansys software programme. The model was verified by means of the digital image correlation system during a pressure test conducted in a testing station. The performed FEM analysis resulted in the obtainment of the states of stress and strain reduced in accordance with Huber–Mises–Hencky's hypothesis. The results of the analysis revealed that the structure of the linear expansion joint meets the safety requirements taking into consideration the service load.
