Title: Method and apparatus for inspection of inside detect of water-wall pipe
Inventor: KANAZAWA TAKAAKI
IPC: G01N29/04
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus in which the incidental operation of the inside inspection of water wall pipe is reduced and in which the reliability of the inside inspection is enhanced by expanding an inspectable range by a method wherein SH waves (ultrasonic beams) out of ultrasonic waves used in an ultrasonic flaw detection are incident from the surface of the water wall pipe and the SH ultrasonic waves are skipped inside the wall thickness of the water wall pipe. SOLUTION: When a furnace-outside corrosion and fatigue defect 6a is probed, an SH-wave probe 57 is used. SH waves which are oscillated from the SH probe 57 are incident on a water wall pipe 4 in a point O on the water wall pipe. After that, they are reflected by a point B on the inside surface of the pipe and by a point A on the outside surface of the pipe so as to reach a point Z after 1.5 skips. When the surface outside corrosion and fatigue defect 6a exists in the point Z, the ultrasonic waves are reflected by the furnace-outside corrosion and fatigue defect 6a, they are returned so the SH probe 57 by tracing their reverse route, and they are observed as a defect reflection echo by a multichannel ultrasonic flaw detector.  When the SH waves are used, the defect can be probed in a nearly constant ultrasonic incident point without being affected by whether the defect is large or small. In addition, a furnace-inside corrosion and fatigue defect 6b is probed by using an angle probe and a normal incidence probe.

In such a way, it is possible to reduce the probability of invalid incoming connection to the mobile station and to efficiently perform the incoming control on a targeted mobile station.
