Abstract
An in-line pipe inspection tool has a sensor carrier carrying a plurality of sensor for monitoring the pipe. In order to permit the sensor carrier and hence the sensors, to conform to changes in the diameter of the pipe being inspected, the sensor carrier is a part cylindrical body which is resiliently flexible. However, to stop one part of the sensor carrier twisting torsionally relative to another part, a bracing unit is fixed to one part the sensor carrier and engages another part of the sensor carrier to resist said torsional twisting.
