A potential-integral-index algorithm for analyzing the pressure fluctuations of gas flows in complex pipelines is proposed. Pressure fluctuations characterize the turbulent structure of gas flows, which exert shock effects on the walls of pipelines, which is one of the most important causes of a dangerous mechanical phenomenon—vibration, leading to the mechanical destruction of the pipeline. At each point in the gas flow, ordered sequences of pressure fluctuations form time series, which can be analyzed using the statistical method of a one-dimensional and two-dimensional time sweep of pressure fluctuations formed when the size of the sliding window, covering different regions of stochastic pulsations, changes. It is shown that the proposed algorithm allows one to find the singular points of the time series that are not detected using the traditional continuous wavelet transform, which plays an important role in assessing the dynamic stochastic structure of pressure fluctuations in pipeline flows.
