The Stress Analysis of Buried Nature Gas Pipeline in Abrupt Slopes. Issue 4 (March 2021) - Liang, Jinqiang
Abstract: The landform of the buried long-distance pipeline is complex and variable, especially in case of mountainous areas, the forces acting on the pipeline is not uniform. We make a calculation on how the gravity of pipeline and fluid in pipeline affects the stress in the bend connected to the front end of the pipeline, and make an analysis of how pipeline parameters and soil parameters affects the stress. We make a stress calculation on the bend with the method of the elastic bending method, and make an analysis of how diameter, thickness of pipeline and angle of slope affect the result of the calculation.
