Abstract
Determination of oil and gas pipeline design coefficient based on experience was conservative in the previous strength design. Most studies at home and abroad demonstrated the feasibility of improving oil and gas pipeline design coefficient in theory, but it didn't give calculation method of design coefficient based on reliability. In this paper, stresssirength interference theory was introduced to the research on design coefficient of oil and gas pipeline. Taking the West to East Gas Pipeline Project and its second project for example, the reliability of pipeline without defect or with volume defect was calculated quantitatively under design coefficient of 0. 72 and 0. 8, practical measures were proposed, and the theories were provided to reduce the oil and gas pipeline wall thickness increase the transportation pressure and save the pipeline cost.关键词
