Apparatus and method for inspecting pipes and tubes using guided wave probes

摘要

(57) Abstract The tube and the flexible pipe of small diameter or to the dot inside cylindrical structural internal the ultra wave and it is the device and the manner which point the mechanical wave which magnetostriction is generated from the dot outside. At the same time this invention although it interposes into tube 24 where it makes target is sufficiently small size and outside the wave is generated inside cylindrical wave guide cancer/gun 10 where it makes the configuration which can maintain the mechanical contact with the inside diameter of the tube 24 which is made target feature is internalized. The canonical sonicator or magnetism deformation,/outside the tube 24 which mechanical wave generation coil 16, 18 and 20 makes target it is laid out on wave guide and 12 at the same time it generates the suitable mechanical wave to the dot inside the tube 24 which is made target via wave guide 12. Wave guide the mechanical boundary aspect 14 with the inside diameter aspects of 12 and the probe, in order inspection wave 36 and for the tube to be able to transmit with 24 which designates the return signal wave 37 which is received as target and wave guide 12, is laid out in one dot inside tube 24 where it makes target at the same time is offered.
