Wax deposition in diesel transportation pipe at low temperatures is one of the harassing problems faced by the diesel transportation companies. In winter, the temperature is very low and the demand of diesel is increasing greatly in northern region of China. This work is focused on proposing a new method to transport diesel at low temperature, by analyzing the operating process of diesel transportation, studying the characteristics of the diesel wax deposition process in pipe by experimental measurements and ensuring the safety of diesel transportation at low temperature. The new diesel transportation method at low temperature built up some key parameters about the process of diesel entering to pipeline and achieved normal operation of the 0# diesel transportation system in winter. This achievement has been added into the operating regulations to promote the application of refined oil pipelines in the northern region.
