ABSTRACT:
A tubular part wall thickness measuring device includes a radiation source having a plurality of radiation sources disposed in a line. The radiation passes through a collimator to provide parallel radiation beams which pass transversely through a tubular part to a radiation detector. The length of the radiation source and the radiation detector are greater than the diameter of the tubular part to be measured so that the radiation passes through an entire section of the tubular part so that the average wall thickness of the tubular part can be determined from the amount of attenuation of radiation which is detected by the detector.
