contents This paper presents an analytical and computational framework for optimizing gas withdrawal in reconstructed ring-type pipeline systems under unsteady flow conditions. As urban and industrial energy demands grow, repurposing existing pipeline infrastructure offers a cost-effective alternative to full-scale expansion. The proposed model identifies the hydraulic coupling point (where the pressure gradient vanishes) as the optimal location for connecting new consumers. By employing a one-dimensional unsteady gas flow model with time-dependent mass extraction represented via a Heaviside step function, the system's dynamic response is captured in detail. Numerical simulations demonstrate that connecting additional loads at the pressure maximum ensures stability while minimizing operational disruptions. The model's validation through benchmark comparison and pressure tolerance thresholds confirms its practical applicability. Economic analysis reveals substantial savings over conventional expansion methods. The approach provides a scalable solution for smart gas network design.
