Pipes carrying various fluids are major structural element for every industry. Industries have been facing many problems including failures in the maintenance of pipelines. These problems as well as failures may have been occurred due to excavation, natural forces, material failure, weldment failure, equipment failure, corrosion, improper operations etc. However, the main reason for most of the failures is due to lack of withstanding strength required for the pipe. Good amount of research has been made in the field of pipeline design especially in the area of stress analysis of pipelines by various researchers on design, manufacturing techniques and their sustainability under various operating conditions, but still not answered many of the ground situations. The Reliance Gas Transportation Infrastructure Limited is a Company which is transferring natural gas from Andhra Pradesh state to Gujarat state through gas pipeline named as East-West Gas Pipeline is observed to be a right area for making total analysis and to identify probable optimization parameters and different materials. In this paper the CFD analysis to determine the pressure and velocity of pipeline carrying natural gas, static analysis to determine the deformation and stress at different materials (stainless steel, carbon steel and lead tin bronze) and models of pipeline. After a good amount of study, it is concluded and suggested the most reliable material for different models of the pipeline. Thus, it has provided a sophisticated solution through computerized analysis.
