A study and analysis of problematic issues in the operation of internal house gas supply networks (VDSG), as well as a study of the accident status of apartment internal gas networks. The analysis of problematic issues during the operation of the VDSG showed that when the volume of the necessary initial information and the detailed analysis are limited only by subjective factors. Based on the results of monitoring gas leaks at the VDSG and gas leaks in the gas supply system, the causes of gas leaks are analyzed and recommendations for their elimination are developed. An analysis of the number of leaks showed that the weakest point in ensuring the safety of the VDSG is gas appliances installed in the apartments of citizens, as well as welded joints on the internal apartment gas pipelines. Studies show that the main factor in damage to domestic gas pipelines (VDG) is the electrochemical corrosion of the outer surface of the pipeline, which occurs as a result of its wetting at the points of transition through the building structures (walls and floors), taking into account the properties of crevice corrosion. It is also necessary to develop and implement a methodology for comprehensive technical diagnostics of internal gas pipelines, to introduce modern technologies for the search for gas leaks due to corrosion. The defects of internal gas pipelines in the places of transitions through building structures were investigated; it corresponds (stage 1) to the development of corrosion damage. At this stage, corrosion damage looks, as a rule, in the form of a so-called “neck”, which is an annular recess in the body of the pipe or its case, located at the place of contact with concrete. The introduction of tread cases from B95 alloy to protect home gas pipelines will significantly reduce the risk of local destruction of gas pipes. Installation of cases does not require additional investment.
