Abstract: On the basis of design throughput of Linji Oil Pipeline and the property of imported oil, the overall thermal calculation is made on with-insulation and without-insulation of the pipeline. According to the geological conditions the pipeline faced wihg, this paper analyzes and compares the heating cost, installation cost and the investment decreased in heating station construction for the two insulation conditions of the pipeline. The results show that the with-insulation program is feasible in technology, but the structure of insulation should be further considered to protect oil burglar.
