Abstract
Abstract
For a long transport pipeline in service in the east, the thermodynamic change rules along the pipeline during shutdown and restart were simulated and analyzed respectively, and the characteristics of soil temperature field during restart were clarified. The change of the dangerous section position was analyzed emphatically, and the reasonable shutdown time was determined according to the temperature of the dangerous section position. The research of this paper can provide theoretical support for the determination of shutdown time in the process of shutdown.
