This study reports applicability evaluations of microwave inspection technique for cracks on inner wall of metal pipes. The experiment is carried out using the straight brass pipe with a diameter of 11.0 mm and the total length of 18.5 m and artificial slits simulating cracks. Experimental result shows significantly large reflections from the slit compared with no flaw, thereby confirming the detectability of this method for cracks in a metal pipes.
