摘要
Abstract
Based on the research of the practical application of two pipelines laid in one ditch in projects ,according to actual projects ,appropriate technical parameters were chosen and the method of numerical simulations was adopted to analyze the feature and discipline of thermal distribution of hot oil pipeline and cold oil pipeline laid in one ditch .On the basis of it ,the thermal stress impact distribution along the two pipelines was respectively studied ,and the variation regularity of thermal stress impact along two pipelines was obtained .Then the increase of the maximum thermal stress impact of the two pipelines laid in one ditch compared with the maximum one of the pipelines laid separately was obtained ,which provided references in application of engineering design ,construction ,maintenance and other periods .关键词
