FIELD: crack detection.
SUBSTANCE: device has control unit and three active supports into one of which detector with spectrum analyzer is built in and into three other ones - piezoelectric plungers with power supplies. Supports representing piezoelectric plungers with power supplies are disposed at ends of pipe in symmetry to support, which has detector with spectrum analyzer. Oscillations are excited in pipe mounted on supports by simultaneous shocks at two symmetrical points of pipe. Quality of pipe is judged from data parameters of spectrum of oscillations generated.
EFFECT: improved truth of crack detection data.
