Abstract
PURPOSE: To accurately detect a leakage defect part by a simple constitution by a method wherein a travelling body equipped with a sensing element for a high frequency sound noise is traveled within an auxiliary pipe which is attached along a pipe line so that a part of the outer wall of the pipe line may become a part of an inner wall thereof.
CONSTITUTION: A notch part 7 having a constant width is installed along the whole length of the longitudinal direction of an auxiliary pipe, and both ends thereof 61, 61 are bonded or fixed with welding to the outer wall of the main pipe line and further, a part of the outer wall of the auxiliary pipe 6. And then, within the auxiliary pipe 6 a self traveleing type or a pressure type travelling body 5 equipped with a detecting element 4 of a high frequency sound noise is traveled. When a defect part exists in the pipe line 1 and a fluid is leaking, a high frequency sound noise generated by the leakage is directly transferred to the inside of the auxiliary pipe 6 and the detection element 4 equipped on the travelling body 5 in running detects said leakage, and the leakage defect part can be detected, based on the detected results.
