Device for inspecting a pipe, in particular with regard to clandestine tapping

Abstract

A device (1) for inspecting a pipe (C), comprises a scraper carriage (2), substantially cylindrical about an axis (X) coinciding with an axis of the pipe (C) and which is inserted into the pipe (C) and propelled by a liquid transported by the pipe (C), and measuring means carried by the carriage (2). The measuring means comprise a first crown (3), carrying a first set of ultrasound transducers (5, 6), arranged on a first circle centered on the axis (X) and of diameter substantially equal to an inside diameter of the pipe (C), alternating a transmitting ultrasound transducer (5) and a receiving ultrasound transducer (6), arranged so that a wave transmitted by a transmitting ultrasound transducer (5) is reflected, by a wall of the pipe (C) facing it, towards a counterpart receiving ultrasound transducer (6).
