摘要： A method and apparatus for measuring the thickness of the wall of a tubular object includes a measurement of the intensity of a radiation beam passing through the walls and quantizing the indicated value of radiation detected by a detector with reference to a predetermined period of time. Data is expressed diagrammatically, and inflection points on the graph line indicating when the radiation beam contacts the outer and inner peripheral walls of the tube are determined and processed to thereby determine the wall thickness. There is also disclosed a method for aligning collimator members utilized in the radiation beam scanning equipment.

摘要： 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.

摘要： An apparatus and method for measuring the thickness of a tube wall while the tube experiences motion relative to the apparatus is disclosed. The apparatus comprises means for generating a radiation beam and means for positioning the beam relative to a tube so that the beam sequentially passes along at least three selected beam paths. Each beam path passes through at least two distinct measuring points within the cross section of the tube wall. At least three measuring points are passed through by at least two different radiation beams. Beam intensity detection means are provided for detecting the intensity of the transmitted beam after it passes through the tube wall, and produces a detected value of the intensity, which is supplied to a processing means which determines the tube wall thickness based upon the detected value after it transmitted through the tube and the known intensity value of the beam before it is transmitted through the tube. The invention is also directed to a means for preventing radial deflections of a tube during measuring comprising pairs of rollers, means for pressing the rollers to the tube and control means for regulating the pressing force that the pressing means exerts on the tube.
