Mathematical models for the determination of the uplift resistance of a gas pipeline


Dr. Mathew Shadrack Uzoma, Dr. OMO Etebu

Transmission or transportation of gas is usually through piping network. The pipings are close conduits of circular crossection. The gas might be transported above or below the earth surface or below the sea bed. The pipes are required to withstand the internal fluid pressure. Gas transmission lines operates at very high pressures. Subject to the type of material the pipe is made of, there is required optimal pipe thickness to withstand the internal fluid pressure. Pipelines do run through places of diverse temperature gradients and the flowing fluid steam is at a bulk temperature. A laid pipeline is subject to different loads: the weight of the pipe, the weight of gas, the weight of the coating materials, the weight of the overlying water or earth mass for buried pipeline. Under the loading conditions the pipes witness different measures of stresses such as temperature stress, longitudinal stress, circumferential stress and radial stress. To provide the right type of supports for a laid pipeline with the view of avoiding buckling of the pipe in service the different loading conditions and the stresses developed must be properly considered. The scope of this work is to generate mathematical models to enable the determination of the optimal wall thickness for the pipe subject to the different loading conditions and the restoring moment to avoid buckling of the pipe for a laid pipeline.
