A device ( 10 ) for supporting an ultrasonic transducer used for ultrasonic defect testing of pipe comprises: a transducer locating portion ( 12 ) adapted for positioning adjacent to a pipe to locate the transducer in proximity of the pipe; and a guide surface ( 14 ) associated with the transducer locating portion such that, when the device is moved relative to the pipe, the guide surface can engage and traverse hindrances in the pipe to such relative device movement. Apparatus ( 50 ) for rotationally positioning one or more of the ultrasonic transducer supporting devices ( 10 ) in proximity of the pipe to enable ultrasonic defect testing thereof, comprises means ( 52 ) for rotating the or each device around at least part of the pipe's circumference whilst maintaining the or each device in proximity of the pipe. In addition, an arrangement for ultrasonic defect testing of lengths of pipe comprises: a support frame ( 150 ) in which two or more carriages ( 50 ) can be supported and moved, each carriage supporting one or more ultrasonic transducers for positioning in proximity of the pipe; and means ( 154 ) for positioning a length of pipe in proximity with one of the carriages.
