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 eliminate the mechanical alteration of the replacement or mount dimension of a sensor unit, by calculating the interval between a material to be subjected to flaw detection and a flaw detection probe as the function of the outer diameter dimension of the material to be subjected to flaw detection and correcting the output of the flaw detection probe on the basis of interval correction coefficient. CONSTITUTION:The interval G between the surface of a part to be subject to flaw detection and the valley part of a V-shaped roll 12 is different according to the outer diameter phiof the material 10 to be subjected to flaw detection. The interval G is the product of the function F1(theta) of the open angle (the angle of the V-shaped roll) of the V-shaped roll 12 and the outer diameter phi of the material 10 to be subjected to flaw detection and a horizontal interval D is the product of the function F2(theta) of the V-shaped roll angle theta and the outer diameter phi of the material 10 to be subjected to flaw detection. Therefore, the interval G and the horizontal interval D are different according to the V-shaped roll angle theta and, as the angle theta becomes larger, the difference of the interval G due to the change in the outer diameter becomes smaller and the change of the horizontal interval D also becomes smaller. In order to correct the change in the sensitivity of a sensor caused by the change in the intervals, the interval between the material to be subjected to flaw detection and a flaw detection probe, when the V-shaped roll is contacted with the surface of the material to be subjected to flaw detection, is calculated as the function of the outer diameter function of the material to be subjected to flaw detection and interval correction coefficient is guided from the correlation of the intervals and flaw detection sensitivity and the output of the flaw detection probe is corrected on the basis of said coefficient.
摘要翻译：目的：为了消除传感器单元的更换或安装尺寸的机械改变，通过计算要进行缺陷检测的材料与探伤探针之间的间隔作为受材料的外径尺寸的函数根据间隔校正系数对探伤探头的输出进行探伤和校正。构成：要进行探伤的部分的表面与V形辊12的谷部之间的间隔G根据要进行缺陷检测的材料10的外径角度而不同。间隔G是V形辊12的打开角度（V形辊的角度）的函数F1（θ）和要进行缺陷检测的材料10的外径phi的乘积，水平间隔D是V形辊角度θ的函数F2（θ）和要进行缺陷检测的材料10的外径φi的乘积。因此，间隔G和水平间隔D根据V形侧倾角θ而不同，并且随着角度θ变大，由于外径的变化引起的间隔G的差变小，水平间隔D也变小。为了校正传感器的灵敏度的变化，当V形辊与表面相接触时，由间隔变化引起的传感器的灵敏度变化，即要进行探伤的材料与探伤探针之间的间隔作为受到缺陷检测的材料的外径函数的函数，计算出要进行缺陷检测的材料，并且从间隔和缺陷检测灵敏度与缺陷检测的输出的相关性引导间隔校正系数基于所述系数校正探针。
