Annotation:
The article considers improvement of oil and gas pipelines operation coated by graphite-polymer material as well as quality control of the protective layer, manufactured from electrically conductive material. The electrically conductive coating of pipes not only increases their operational efficiency, but also allows effective removal of static stress that occurs when fluids move through pipelines. A model of the medium transfer process in a graphite-filled polymer material, which is a semiconductor with a P-type conductivity, is presented. A model of the process of medium transfer into the bulk of the material and the relationship of this process with the electrochemical characteristics of the material that appear on its surface is shown.
