Abstract :
Negative pressure wave will spread on both sides of the pipeline when a natural gas pipeline leaks, and that will make the pressure in the pipeline reduced. Then a slight deformation will happen to the diameter of pipeline, The Fiber Bragg Grating (FBG) strain sensor which is stuck on the pipeline can detect that and send the signal to us. Based on that signal, by using signal correlation processing method, we can find whether the pipeline leakage.
