Optimization and Stress Analysis of Underground Oil Pipelines in High and Steep Slope Areas
نویسندگان
چکیده
Underground oil pipelines are made of pressurized pipes, and when damage occurs, the consequences can be disastrous. Pipeline accidents caused by stress can be attributed to material corrosion, impractical design, manufacturing defect, environmental damage, and man-made destruction. In this study, by utilizing the stress analysis software CAESAR II, the stress of pipelines in high and steep slope areas was analyzed under the same operating conditions and different piping technologies. Comparing the different simulation consequences of each pipeline technology, an optimized laying process was proposed to reduce the stress of underground oil pipelines in high and steep slope areas; this process was named Sectional Pipe Laying Process. According to the results of CAESAR II, the stress and movement of underground oil pipelines in high and steep slope areas were drastically reduced and the safety greatly enhanced.
