Non - destructive leakage detection of ship pipeline based on dynamic pressure signals

In this paper, a non-destructive leak detection method for ship fluid pipelines is proposed by the means of piezoelectric sensors. The advantages and disadvantages of existing pipeline leakage detection are compared and the working principle of pipeline leak detection based on piezoelectric dynamic pressure transmitter is introduced. The frequency and domain characteristics of the pipeline leakage signal based on the piezoelectric dynamic pressure transmitter are analyzed and the corresponding detection and positioning methods are given as well. Practical applications show that this method can quickly and accurately determine whether a leak occurred and calculate the leak location.
