Abstract：In view of the leakage location inaccurate problem caused by interaction of leakage noise between each leakage point, research was conducted to realize the location of multiple leakage points of pipeline. A multi - leakage point location method based on iterative recursion was developed. The influence of the threshold signal to noise ratio and iteration termination condition on the performance of the algorithm was studied, and the best input parameters were optimized. Experiments proved that method can be used to estimate the number and position of leakage points in pipeline, its error was less than 1m.This work had provided a feasible solution for the detection and location of multiple leakage points in practical engineering pipelines.
