Research Progress in the Shutdown Temperature Drop of Buried Wax Oil Pipelines

New research progress in shutdown temperature crop of buried wax oil pipelines in China was introduced. Influence of latent heat of wax precipitation during the shutdown on crude oil temperature field was discussed as well as the necessity of dealing with solidification latent heat. Based on the heat transfer theory, a new mathematical model was established with the method of apparent heat capacity. The temperature drop of hot oil pipelines is a common phenomenon in oil pipelines, research on the temperature variation of wax oil pipelines will provide some theoretical references for scientific design and economic-safe running of oil pipelines.
