PROBLEM TO BE SOLVED: To provide a device and method for monitoring the inner surface of piping, capable of allowing an inspector to readily monitor the inner surface state of the piping from the outside of the piping, and capable of performing the accurate wall thickness reducing control of the piping by an ultrasonic flaw detection test. SOLUTION: The device for monitoring the inner surface of the piping 11 is equipped with the piping inside moving member 12, which is loaded with a camera for photographing the inner surface of the piping 11 and runs through the piping; a piping surface running member 13 running on the surface of the piping; an alignment device 24 for aligning the piping surface running member 13 with the piping inside moving member 12 so that the piping surface running member 13 may run in connection with the piping inside moving member 12; a projector 25 mounted on the piping surface running member to project the image which is photographed by the camera 23 of the piping inside moving member on the surface position of the piping, corresponding to the inner surface position of the piping; and a remote controller 15 for controlling the running of the piping inside moving member 12 and the piping surface running member 13.
