Long-distance natural gas pipelines can often pass through the common slope safely. However, when pipelines inevitably pass through high and steep slopes(HSS) for some reasons, it is difficult for engineers to predict the stress state of pipelines. Therefore, in order to investigate the safety of natural gas pipelines in HSS areas, the finite element simulation calculation model of the pipeline in HSS was established. The predicted numerical model shows that the maximum Von Mises stress and axial strain of the pipeline in the HSS area appear at the lower elbow of the pipeline, which should be paid more attention to in the risk assessment; The stress and deformation of the pipeline is mainly related with the wall thickness and internal pressure, appropriately increasing the wall thickness and reducing the internal pressure can improve the safety of HSS pipelines.
