A NEW METHOD OF RAPID DEFINING POWER CONSUMPTION OF ELECTRIC HEATING OF ABOVEGROUND "HOT" TRUNK OIL PIPELINES

Abstract

The article describes the principle of nomographs building that make it possible to quickly determine the required power consumption of the electric heating systems for stationary thermal operating mode of a pipeline. For pipelines with standard outside diameters, dependency of the linear and power type of the required linear power consumption of heat tracing on the average oil temperature has been shown. Also, tabular and graphical forms that simplify the process of calculating the required thickness of pipeline thermal insulation have been shown. The obtained dependences, charts and nomographs make it possible to calculate the thermal mode of a "hot" trunk oil pipeline with the minimum amount of source data. The results shown in the paper have been obtained with the accuracy sufficient for calculation.
