FIELD: nondestructive testing.
SUBSTANCE: defectoscope comprises magnetic system and Hall-effect transducer. The magnetic system and Hall-effect transducer are mounted in a pressure-tight housing. The transducers are aligned and spaced by (0.3-0.5)T, where T is the thickness of the wall of the pipe to be tested. The top side of each transducer is a tangent to the plane of the faces of the poles of the magnetic system. The planes of the transducers are parallel to the magnetic force lines in the space between the poles.
EFFECT: enhanced reliability.
