Abstract: An apparatus for monitoring a fault of a pipe according to an aspect of the present invention includes a processor, and a memory configured to store instructions executed by the processor, wherein the processor generates an ultrasonic guided signal in a pipe through piezoelectric transducers disposed on a circumferential outer surface of the pipe which is a target of which a fault is to be monitored, and monitors a fault of the pipe through signal processing for performing correlation analysis and noise removal on a reflected signal generated by the ultrasonic guided signal being reflected at an arbitrary point of the pipe.
