Abstract: A device for positioning two threaded pipes being threaded together within a target range of relative axial positions, which device generally includes a sensor base, and a calibrating device for positioning the sensor base a calibrated distance from the end of one of the pipes. The device further includes a sensor head extending from the sensor base, for abutting the end of the second threaded pipe during the threading of the pipes together, to indicate a relative axial position of the pipes. The device even further includes a signal generator that generates a signal once the sensor head indicates the relative axial position of the pipes are within the target range of relative axial positions.
