Maintenance of Gas Networks The diagnostics is carried out through technical examination, tracking their route, pressure measuring, mode modelling (computer monitoring), gas balance control, in-pipe diagnostics with intelligent monitoring pigs (next slide). Tracking the gas pipe line route main pipelines with pressure ≤5,5 MPa – once in 2 months; gas pipe line with pressure ≥0.4 MPa – twice a month at least; gas pipe line with pressure ≤0.1 MPa and Main Branch Pipeline from an Automatic Gas Regulation and Measuring Station outside a built-up area– once a month at least. Tracking the route of the distribution networks involves the following activities: measuring of the safety potential of the cathode station for metal gas pipelines; check-up of working pressure in Gas Regulation Station and Gas Regulation and Measuring Installations; reflecting any construction and assembly works under way in the proximity of the gas pipelines; check-up for the presence of natural gas in the shafts of other utilities (communication, sewage) etc. the minimum time span of the technical examination for steel gas pipelines is once in 4 years;
