Abstract
Tube inspections are performed by combining the use of APR technology with GW technology. The reflections measured by both technologies are compared to each other and used to more specifically identify the type and location of a flaw or anomaly that appears in the interior of the tube. Further, embodiments of novel probes to be used in GW technique for inspecting tubes with mechanical waves having bandwidth that is equal to 150 KHz or more are disclosed.
