Item PARAMETRIC STUDY OF OIL AND GAS INTERNAL PRESSURES IN BURIED PIPELINES(2014-07-09) SHAALAN, Heyam Hussein; SARI, Yasin DursunThis study presents a parametric analysis of the behavior of buried oil and gas pipelines in different soil condition, subjected to static loading, where the influence of fluid internal pressures is taken into account. The crown steel pipe displacement has been computed numerically with respect to the applied surface loads for different burial depths of soil conditions (dense sand, loose sand and clay). The mechanical behavior of pipes is evaluated by means of a two- dimensional finite element method PLAXIS. A large number of the calculation results were analyzed and evaluated. On this basis, the results were fitted by non-linear regression analysis. This study is concerned with the effect of soil media (dense sand, loose sand and clay), burying depth, fluid materials (oil and gas), location of applied load, adjoin pipes, internal fluid pressure and mechanical parameters of pipe (such as pipe diameter and pipe wall thickness).Comparison was also carried out.
