Technological equipment of oil and gas processing under certain technological processes is simultaneously operated both in conditions of corrosive working media and in cyclic loading mode. Under such conditions, the probability of premature destruction increases significantly. Corrosion wear contributes to the exhaustion of the safety margin, and cyclic loading contributes to the formation of fatigue cracks. Regulatory documents regulate control methods for detecting the degree of corrosion wear and fatigue cracks. However, the most interesting scientific topic is the study of the relationship between the rate of metal corrosion and the level of accumulated damage in the aggregate. Therefore, research on the development of new methods, as well as diagnostic features to determine the zones of possible destruction under operating conditions of objects with simultaneous exposure to corrosion wear and cyclic loading, is relevant. The authors suggest that in metal zones with the maximum level of accumulated damage, the corrosion rate may be the most intense.
