FIELD: ultrasonic testing.
SUBSTANCE: ultrasonic testing of threaded joints of drill pipes. The essence of the invention is that a piezoelectric transducer is introduced into the pipe from the side of the nipple and the thread and the body of the upset part are controlled from the inside. The technical result is providing the possibility of eliminating the need to use the outer surface of the pipe during ultrasonic testing of threaded joints of drill pipes, wherein cleaning from dirt and oil is required on the outside, where the pipe also has many scratches, rough surfaces and other damages after drilling, such damages not allowing for good contact of ultrasonic sensor with the surface of the controlled object.
EFFECT: possibility of eliminating the need to use the outer dirty surface of the pipe during ultrasonic testing of threaded joints of drill pipes
