damage over the last 25 years of operation of the MG. At present, during the industrial safety examination of gas pipelines, the calculation of the residual resource for thinning the wall of the gas pipeline is carried out according to the current regulatory and technical methodology. To do this, measurements are made of the actual thickness of the walls of the gas pipeline in sections with a frequency of 1-2 kilometers of the route. The probability of finding a local focus of corrosion with this technique is very low. The corrosion damage described above at the last stage was accompanied by the occurrence of fistulas and gas leaks. Thus, to detect local foci of corrosion at a critical stage of their development, continuous diagnostics using modern methods for detecting natural gas leaks is recommended. It is also necessary to take into account the growing likelihood of local References Bolshakov, A.M., 2012.
