- Abstract
To prevent upheaval buckling or even leakage of high temperature buried pipe-in-pipe pipeline, it is of significant benefit to properly simulate the global bucking process and take suitable measures, thus to reduce the axial compression force and improve the global stability performance. A high temperature oil-sand pipeline is taken as an example, and dynamic leakage, pipe-soil interaction and upheaval buckling process is simulated using software OLGA and ABAQUS. Technical measures to alleviate high temperature instability of pipeline are put forward. The leakage and upheaval buckling dynamic simulating method can properly simulate the buckling process of the buried pipe-in-pipe pipeline, and can be used in pipeline failure cause investigation.
