Analysis of Suspended Pipeline Stress Sensitivity

Abstract:

Natural gas pipeline laying process will inevitably go through some of the earthquake-prone areas, these areas of soil subsidence, will cause the pipeline vacant, vacant section of the pipeline failure may cause pipeline rupture. Effects of suspended pipeline stress safety usually have two factors: suspended length and the buoyancy of water. In order to explore the sensitivity of these two factors on suspended pipeline stress, we do numerical simulation of XX suspended pipeline using the general stress analysis software CAESAR II. Research shows that suspended length of pipe is having a greater sensitivity on pipeline stress, and the buoyancy of water is relatively small. The results provide some reference for safety management and selection of pipeline.
