Specifics of Using Two-Electrode Method of Intensive Measurements for Determining the State of Corrosion-Resistant Coating of Main Pipelines of the Western Siberia

摘要

Integrity of anti-corrosion coating of the main pipeline is a prerequisite for system survival of the entire oil and gas transmission system. Currently, most of the main pipelines of Western Siberia are being operated for 25-35 and more years, and therefore relevance of the problem of controlling their state of isolation is not doubted. Enterprises operating gas and oil pipeline network of great extent, no doubt are interested in qualitative monitoring and adequate interpretation of the results. This paper represents some diagnostic testing results of insulation coating state of main pipelines by a two-electrode intensive measurements method, on the basis of which, recommendations on optimization of this type of work in the conditions of Western Siberia are presented.
