Abstract

1,270,387. Ultrasonic inspection devices. INTERNATIONAL RESEARCH & DEVELOPMENT CO. Ltd. 30 May, 1969 [7 June, 1968], No. 27194/68. Heading H4D. [Also in Division F1] Ultrasonic apparatus for the inspection of the weld between a heat-exchanger tube 2 and tubeplate 3 comprises an expandable plug la, 1b, forming a fluid-tight seal with the inner wall of tube 2, a housing 5 sealed at 9 to the tube plate 3 to define with space 4 a chamber for containing an acoustic coupling liquid, a transmitting/receiving transducer 10 and an adjustable mirror 12 for directing ultrasonic waves from the transducer to the weld, the transducer and mirror being mounted on a common driving shaft 41 capable of rotational and longitudinal movement. In use, plug la, 1b is expanded to fit the tube bore by actuating pneumatic ram 18 to retract rod 16 through coaxial sleeve 15 and so compress the plug axially between discs 15a, 16a; housing 5 is then pressed against plate 3 by turning nut 6. The transducer and mirror orientations are set up at 11, 13 so that the ultrasonic beam is normal to the tube wall at the weld zone. Shaft 14 is rotated back and forth by a pinion 23 meshing with a linear rack which is reciprocated by a pneumatic control system (see Division F1). A cam on the rack drives a cam-follower and pawl for engaging a circular ratchet to index shaft 14 longitudinally between each rotation. Echo pulses from the weld region are fed to conventional ultrasonic flow detectors for display against a time scale: good welds produce little ultrasonic reflection at the tube/tube-plate interface.
