Abstract: Mining and oil and gas enterprises use various pipeline designs and pipe fittings to transport various combustible, explosive, toxic and other hazardous media, both liquid and gaseous. To prevent emergencies leading to production downtime, harming the life and health of personnel, as well as affecting the environmental situation, modern technical means are required to detect emerging defects in a timely manner and with sufficient accuracy. The article justifies the relevance to use nondestructive testing methods in assessing the technical condition and residual life of pipelines and shut-off valves of mining and oil and gas sector enterprises. The prospects of diagnosis by the method of analysis of excited oscillations are proved. The design and algorithm of operation of the Kamerton diagnostic complex produced by the ROS Research and Production Enterprise (Perm) are described. The methodological basis of defect finding using the Kamerton multichannel analyzer are described. The main characteristics of the registered signals are listed that characterize the condition of the elements of the technical facilities based on the results of diagnostics. In terms of efficiency and timely response, the method has no analogues in comparison with traditional methods of non-destructive equipment testing, e.g. the magnetic, eddy current, ultrasonic flaw detection, ultrasonic thickness measurement, radiation, radio wave, penetrating substances control, and other methods. In some cases, for example, for the elements made of ceramics, materials of heterogeneous structure such as polymers or concrete, the proposed method is the only possible diagnostic method.
