NOVELTY – The method involves issuing of high-frequency sounds on the evaluating surface. The sound causes the vibration of the mechanical equipment of the constituent components according to the geometry, mass, structure and chemical composition and depends on the frequency and magnitude of excitement caused. USE – Method for non-destructive measurement, particularly ultrasonic measurements of mechanical stress in oil pipelines. ADVANTAGE – The method involves issuing of high-frequency sounds on the evaluating surface, and hence ensures fast measurement at low cost and with little interaction with the operator and also avoids the errors of measurement. DETAILED DESCRIPTION – An INDEPENDENT CLAIM is also included for a system for non-destructive measurement, particularly ultrasonic measurements of mechanical stress in oil pipelines.
