Testing of the developed criteria in laboratory conditions is carried out on the basis of testing of pipe elements with the use of the developed method of diagnosing pipelines, which is based on the phenomenon of change of the electrode potential of a metal depending on the degree of its flooding. The application of the obtained results is shown to develop the methodological bases for the assessment of the technical condition and substantiation of the safe life of the pipelines under the action of hydrogen-containing media.
