摘要： PROBLEM TO BE SOLVED: To stably and accurately measure the wall thickness configuration of a pipe having a portion of which wall thickness changes largely at not only a bead cut portion but also a seam-welded pipe welded portion including a thickened wall portion. SOLUTION: This wall thickness configuration measuring device of a pipe measures the wall thickness configuration of a seam-welded pipe 2 while running the ultrasonic beam generated by each ultrasonic probe 1-1 to 1-N of a linear array type ultrasonic probe 1 arranged outside the seam-welded pipe 2 in a cross section which crosses the seam-welded pipe 2 in the axial direction. In the linear array type ultrasonic probe 1, the plurality of ultrasonic probes 1-1 to 1-N are array-arranged which generate ultrasonic beams, each of which forms a cylindrical wavefront extending in the cross section and is radiated toward the axis of the seam-welded pipe at least, and whose axial component BMC has intensity larger than a predetermined value. The device includes a wall thickness operation part 8 detecting the seam-welded pipe 2 outer surface echo and seam-welded pipe 2 inner surface echo of the axial component BMC of the scanned ultrasonic beam and measuring the wall thickness configuration of the seam-welded pipe 2.

摘要： PROBLEM TO BE SOLVED: To realize tandem flaw detection even for a steel pipe with thickened wall portions on inner surface.
SOLUTION: This device is provided with a transmitting part 6 for making an ultrasonic wave incident into the weld zone of a welded part 2 in a pipe axis direction of a pipe (steel pipe 1) and a receiving part 7 for receiving a part or whole of the reflected wave 9 reflected by the welded zone 2. The transmitting part 6 and the receiving part 7 are equipped with a transmitting/receiving part arranged in a circumferential-direction of the pipe composed of one or two or more different oscillator groups on the array probe 5 for detecting flaw. When flaw of the pipe 1 is detected with this ultrasonic flaw detecting device, the wall thickness of the pipe 1 is measured and the propagation path of ultrasonic for scanning in the thickness direction of the pipe 1 are computed using the array probe 5 for detecting flaw based on the measured thickness distribution. Based on the computed propagation path, the oscillator groups corresponding to the transmitting part 6 and the receiving part 7 on the array probe 5 for flaw detecting are changed, or the angle of the array probe 5 for detecting flaw is controlled to be changed for scanning in the thickness direction of the pipe 1.

摘要： PROBLEM TO BE SOLVED: To prevent the generation of excessive displacement upward from the pass line and nose break, tail end break or the like due to the displacement by making a hot-rolled steel strip stably run on a run out table. SOLUTION: By jetting a fluid jet stream so as to pass through the upper part of the hot-rolled steel strip without contacting with the surface of the hot-rolled steel strip which is passed through on the pass line ( provided the steel strip conveying face of the run out table ) and making the steel strip part where is upward displaced exceeding a prescribed level from the pass line collide against the fluid jet stream, the displacement in this steel strip part is straightened. The displacement of the steel strip by the fluid jet stream is also suitably prevented because the fluid jet stream is passed through the upper part of the steel strip perfectly without contacting with the hot-rolled steel strip which is normally passed through.

摘要翻译：要解决的问题：为了防止由于通过使热轧钢带在耗尽台上稳定地运行而导致的位移，从通过线和鼻部断裂，尾端断裂等产生过大的位移。解决方案：通过喷射流体喷射流以穿过热轧钢带的上部，而不与在通过线上通过的热轧钢带的表面接触（提供钢输出台的带状输送面），使得从通过线向上移动超过规定水平的钢带部件与流体喷射流碰撞时，钢带部分的位移被拉直。由于流体喷射流完全通过钢带的上部而不与通常通过的热轧钢带接触，所以也适当地防止了由流体喷射流引起的钢带的位移。版权所有（C）2005，JPO＆NCIPI
