The Influence of Gas Source Conversion on Flow and Reliability of Gas Pipe Network

Maximal operation pressure, minimal allowed pressure, number of source points have greatest impact on flow and reliability of pipe network. The change of the three design parameters before and after conversion are analyzed. Through the analysis of problems on the artificial gas pipeline network in Changchun City, point out that removing extra loops is the main optimization means. The hydraulic calculations have been made for optimized pipe network, and compares the flow capacity and hydraulic condition of the pipe network before and after conversion.
