【 摘 要 】

To assess the resource of safe operation of process of technological pipelines, it is proposed to control the technical condition of the pipeline metal using the method of dynamic identification. The method is based on the analysis of the coordinates of the roots of the denominator of the transfer function on the complex plane. The transfer function of the system "object of control-electromagnetic-acoustic transducer" is an integral quantitative parameter characterizing the state of the metal.
