Abstract: The Jing′an-Xianyang pipeline is 463km long with 6 pump stations and monitored and managed with SCADA system. PIPELEAK3.1 software, which is written based on the priciple of negtive pressure wave by Beijing SinoCanadian Cheng-xin Pipeline Co, is used there for warning and monitoring pipe leaking. Valve stations in three pipe segments are choosed for leaking experiment to validate the applicability of PIPELEAK3.1 software at Jing′an-Wangyao section, Yangshan-Luochuan section and Yaoxianxianyang section. The experiment result shows that the system can have timely and accurate orientation and calculate the leaking amount when pipe is full of fluid. However, the actual condition is complicated because of the disbennifit caused by the full fluid condition and application distraction caused by oil stealing. Therefore, operators should make particular analysis based on actual condition and combine with other monitoring ways to put the system in good use.
