Abstract
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.
Highlights
Pipeline systems, one of the most important aspects of crude oil transportation, have always been seen as the arteries of the oil energy industry, and the safe and effective operation of these arteries is vitally important
Ductile failure of underground oil pipelines in high and steep slope areas was researched for this paper
The results suggested that under any piping process, bends are the danger points for pipeline stress, and under different working conditions, the causes of stress can be different [2]
Summary
One of the most important aspects of crude oil transportation, have always been seen as the arteries of the oil energy industry, and the safe and effective operation of these arteries is vitally important. The safety of oil pipelines laid in complex areas is threatened by various factors such as natural hazards, local stress, and man-made sabotage Out of these complex areas, the most dangerous areas are high and sleep slopes. Underground oil pipelines in high and steep slope areas were researched. Ductile failure of underground oil pipelines in high and steep slope areas was researched for this paper. In 2014, Wu Xiaonan, Lu Hongfang, and Huang Kun researched the stress of natural gas pipelines in earthquake zones based on spectrum analysis.
