The work reveals the features of the decrease in reliability and the state of safety during gas transportation due to changes in the hydrodynamic parameters of the flow and impurity indicators of gas in pressure gas pipelines, the establishment of regularities in the change in the hydraulic and quality indicators of the gas flow, the development of scientifically substantiated proposals for the creation of a reliable and safe gas supply system. The results of experiments prove that a multiple increase in the concentration of impurities of a different nature in the gas supply units is due to a violation of the hydraulic mode of the system. The exponentially increasing, exponentially decreasing, as well as linear laws of regulation of gas supply rates determined the mechanisms of changes in the concentration of impurities of various nature, as well as changes in pressure in the gas supply system along the entire length. It was taken into account that the movement of gas in pressure pipelines refers to the quadratic region of resistance (self-similar movement), hydraulic modeling is carried out using the criterion of dynamic similarity - the Froude criterion. This criterion characterizes the relative magnitude of the force of gravity, it is decisive in cases when gravitational factors play a significant role for the movement of gas.
