摘要： PURPOSE:To improve outside-diameter range responsivity and measuring accuracy of a tubular member, by changing a irradiation width of a beam by changing a distance of a plurality of individual radioactive source arranged in parallel in the direction of width of a broad radioactive beam. CONSTITUTION:At the beginning, a threaded rod 24A is turned with alignment with an outside-diameter P of a tubular member 10 to adjust an irradiation width L in such a way that the width L of a broad radioactive beam 14 is larger than the outside-diameter D of the member 10 and ratio of attenuation amount (NO-NS) to the total radioactive emission rate NO becomes optimum. Next, for uniformizing radioactive intensity distribution in the transversal direc tion of the broad radioactive beam corresponding to distances among individual radioactive sources 22A, 22B and 22C, a shielding 26A is turned for adjustment of the radioactive intensity of the central individual radioactive source 22B. Then, the specified standard specimen is inserted in the specimen space and after organizing divisions for wall-thickness measurement, an on-line measure ment is started.

摘要： PURPOSE:To measure thickness accurately even when local fluctuations of external diameter size and thickness size are large by setting odd-numbered measurement points in the section of a pipe wall at the vertexes of a regular polygon and by measuring the transmission intensity of radiation in the direction of each side of the polygon. CONSTITUTION:In the section of a pipe, three measurement points, for example, are set at vertexes 1-3 of a regular polygon, and radiation sources S-1-2-S-3-1, and detectors D-1-2-D-1-3 are provided along sides 1-2, 2-3 and 3-1 of the triangle to measure the transmittivity of radiation. Then when the transmission coefficient of radiation is known in advance and the radius of a circle running through three points 1, 2 and 3 is R0, the nominal radius of the pipe is used while the width of a radiation beam is disregarded, and fine arcs of external and internal circles near the measurement points are made to approximate by arcs concentric with the circle 123, thus calculating the radius-directional thickness easily. Consequently, even when local fluctuations of external diameter size and thickness size are large, the thickness is measured accurately.
摘要翻译：目的：即使通过在正多边形顶点的管壁部分设置奇数测量点，并且通过测量辐射的透射强度，即使当外径尺寸和厚度尺寸的局部波动较大时，也可精确测量厚度多边形的每边的方向。构成：在管道的部分，例如，将三个测量点设置在正多边形的顶点1-3处，并且辐射源S-1-2-S-3-1和检测器D-1-2 沿三角形的侧面1-2,2-3和3-1设置-D-1-3以测量辐射的透射率。然后当预先知道辐射透射系数并且通过三点1,2和3的圆的半径为R0时，使用管的标称半径，而辐射束的宽度被忽略，并且细弧使测量点附近的外圈和内圈与圆123同心圆弧近似，从而容易计算半径方向厚度。因此，即使当外径尺寸和厚度尺寸的局部波动较大时，也能够精确地测量厚度。

摘要： PURPOSE:To measure the thickness of a pipe effectively even when it is rotating or running, by measuring the positions of the external and internal diameters of the pipe actually at the same time by using a photoelectric detector having a high response speed and a beam position measuring instrument. CONSTITUTION:For the measurement of the thickness of, for example, a seamless steel pipe 1 in rotating or running motion, a container 4 containing a radiation source 3 and a frame 9 supporting a radiation beam detector 10 are driven as shown by an arrow 12 or 13 by a motor 7 through a rack 5 couled with the frame 9 and a pinion 6. With a radiation beam 2 entering the detector 10 through collimators 8 and 8a, the internal diameter position L2 of the pipe 1 corresponding to a reference point S2 is measured through a linear scale 25 and a pointer 26. Simultaneously, the internal diameter position L10 corresponding to a reference point S1 is measured by detecting the self-emitted light of the pipe by a photoelectric detecror 11 driven by a motor 7a. Consequently, the thickness of the pipe 1 in rotating or running motion is meaured effectively.

摘要： PURPOSE:To measure the thickness of the pipe wall in a high accuracy and with no contact, by transmitting the radiation beam twice through each point of measurement of the selected tubular material and with variation of the incident angle and then measuring and calculating the intensity of the transmitted beam. CONSTITUTION:The system of measurement is formed with the heat source 1 which radiates the radiation beam 3 in correspondence to the points A-C dividing equally the pipe circumferential length of the tubular material 20 into three parts, the container 2 which gives an orientation to the beam 3, and the detector 4 which detects the beam transmitted through the pipe wall respectively. Thus one beam can transmits through two points of measurement, that is, the two beams transmit through one point of measurement. At the same time, the outputs of detectors 4A-4C detecting the beams transmitted through the pipe wall are defined as I1-I3, and the detection outputs in the case of nonexistence of the pipe wall are defined as I10- I30 respectively. Then the simultaneous equations expressing the thicknesses x1- x3 of points A-C are calculated by the outputs I1-I3 plus I10-I30. As a result, the x1-x3 can be obtained.

摘要： PURPOSE:To enable measurement of correct distance, by using a radiation detector itself in place of an optical rangefinder to measure distance. CONSTITUTION:The gamma ray detection value of a detector 21 is represented by D1 as positioned at a distance L from a radiation cource Q which radiates gammarays in numbers of (q) per sec spherically. The detector 21 is made movable horizontally on a rail 8 through a slide 9. The ray detection value D2 is measured at the point shifted by a distance l from the distance L position. The distance L to the radiation source and the intensity (q) of the radiation source Q are measured by a specified formula based on the gamma ray detection values D1 and D2 and the distance l. Thus, the distance to the radiation source and the intensity thereof fare measured with only one detector 21 thereby avoiding effect of a non-transparent body existing in the cource while eliminating any rangefinder.

摘要： PURPOSE:To ensure a simultaneous and contactless measurement for thickness of a tubular material, by shifting the tubular material toward its axis, decentralizing the measuring systems along the shift direction of the tubular material and then supplying the measurement value signal into an arithmetic device with a time delay and in accordance with the shift of the tubular material. CONSTITUTION:Three sets of measuring systems 1, 2 and 3 in which the ratiation beam sources and the detectors are combined are used, and 1-1, 1-2, 1-3 and 1-4 are used for the radiation beam sources of the 1st measuring system 1. In the same way, 2-1-2-4 and 3-1-3-4 are used for the radiation beam sources of the 2nd and 3rd measuring systems respectively. A pipe 5 to be measured is shifted toward an arrow mark in a speed v and without turning round the axis of the pipe. The systems 1-3 are installed with spaces l1 and l2, and the output signals I1', I2' and I3' obtained from these systems are used to obtain the three points on the tube circumference of the pipe 5. Then the value of lateral section at the same part of the pipe 5 is supplied to a signal processor 10 according to the rotational frequency of a roll 6. Thus the thickness of the pipe 5 is measured.
