At that, the local hydrogen concentration near crack tip has been measured by method of mass-spectroscopy with laser microprobe. The specificity and mechanism of hydrogenating of long-term operated pipelines were determined and comparative assessment of these processes with respect to the non-exploited pipes was done.
