Abstract
The capabilities of the nondestructive ultrasonic method for evaluating stresses are demonstrated by an example of measuring non-design axial stresses in technological pipelines. The results of applying the acoustoelasticity effect, which was implemented in an IN-5101A device, obtained in direct in situ measurements of mechanical stresses in piping structures of the main equipment of compressor stations are presented. The features of applying the acoustoelasticity method for measuring stresses in these objects and its prospects for solving the problem of periodic testing of a stressed state of pipeline systems are considered.
