In the process of transportating the natural gas, pipeline leakage is one of the important factors affecting the safe operation of the pipeline. In this paper, causes of gas pipeline leakage were introduced, and several common pipeline leak detection methods and leak location methods were discussed, such as direct observation method, ultrasonic method,the method of distributed optical fiber, transient simulation method and negative pressure wave method. According to different leakage causes, corresponding preventive measures were put forward basing on the contrast research.
