Carrying out thermal calculations of “hot” oil pipelines, through which highly viscous and high pour point oils are transported, is one of the main ones. Determining the cooling rate of oil in a stopped oil pipeline is of great practical importance. The cooling time is used to calculate the safe stop time of the “hot” oil pipeline. The time at which there will be no freezing of the “hot” oil pipeline, and the station pressure is enough to overcome the shear stresses that arise when cooling highly viscous and high pour point oil. The methods of finding the cooling time of oil in a stopped pipeline are considered, which allow determining the time of a safe stop of the pipeline. Installed thermal stabilizers designed for cooling the soil can affect the cooling rate of the “hot” oil pipeline.
