| Abstract: | A model of electrical heating buried pipelines is set up on the basis of considering the effect of ground temperature?soil temperature field?pipeline diameter?operating parameter?properties and other relative factors. A computational procedure has been done. The calculated results are well agreed with tests and the computational procedure has been used to the actual project's design. Experiments are worked out for resuming theory in small-scale system of electrical heating buried pipelines. A correlation between the electrical heating power, medium temperature inside pipeline and soil temperature has been developed. |
