Transportation of mixtures of natural gas and green hydrogen is one of the promising ways to use the local gas-transportation system under the conditions of a rapid transition to a sustainable economy. For safe operation of the available main gas pipelines at transportation of gas-hydrogen mixtures of different compositions, it is necessary to take into account the negative influence of hydrogen on the mechanical properties of pipe metal, in particular at evaluation of their technical condition by the results of flaw detection. In this work, the principles of safe operation of pipelines with detected defects of local corrosion loss of metal were studied. For this purpose a numerical procedure was developed for assessment of brittle strength based on finite-element modeling of the stressed state and brittle-ductile fracture criteria. It is shown that under the conditions of static loading degradation of brittle fracture resistance of pipeline metal with the detected defect of local metal loss is relatively small, and it can be compensated by a change in service load. Under the conditions of cyclic loading by internal pressure the regularities of lowering of the load-carrying capacity of a corroded pipeline were demonstrated, depending on the actual brittle fracture resistance of the pipe steel. 18 Ref., 6 Fig.
