Experiment Research on Effect of Leak Point and Load Point's Distribution on Gas Leak Pipeline Network

Abstract:

For studying the difference of gas pipeline’s pressure between leakage condition and normal condition, a simulated network of city gas pipeline network based on principle of similitude was builded. Put this simulated pipe network as a experimental platform, we designed four sets of experiments. In each set of experiments, the pressure of each node in the leaked condition were compared to normal condition, to analysis the characteristics of node’s pressure change and summarize its change rule. It was found that regardless of the leak and load point how distribute in the pipe network, the differenal pressue between normal condition and leakage condition of leak point is largest, the pressure change of the node on the pipe which leak point is located is also large; pressure change of network is small relatively while leak and load point were farther; the closer from the gas source point, the node’s pressure change is more small.
