Today our country devotes much attention to the problems of efficiency and quality of operation of pipeline transport, as for transportation companies of Ukraine on the issue of gas delivery to the consumer without a loss it is still relevant. The article describes the results of numerical simulation of flow regimes of gas through the pipeline section of the method of characteristics. This method differs from the existing way of solving systems of nonlinear equations obtained after the application of the method of characteristics to the original system of equations of the mathematical model. The method allows for the calculation of the gas flow parameters with the required accuracy and desired performance.
