摘要： Rolled steel plate is press-fabricated into cylindrical UO pipe with a large wall thickness, by the steps of crimping, U-ing and O-ing. In the U-ing process, a collapsible U-ing punch, including a center block carrying paired side punches on both sides and a bottom punch at the bottom, is used. The U-ing punch insures that the O-shaped workpiece has the desired butt gap by decreasing the ratio of its height to its width when the gap proves to be smaller than the desired butt edge gap, and vice versa when the gap proves to be larger than the desired butt edge gap.

摘要： An X-ray radiation apparatus comprises a synchrotron 11 that generates X rays, an X-ray reflecting mirror 13 that reflects X rays emitted from the synchrotron 11, a mirror driving mechanism that enlarges the X-ray illumination area by oscillating the mirror 13, a beryllium window 14 that is connected to the synchrotron-side housing base containing the mirror 13 by means of a bellows 17 and that allows the X rays reflected by the mirror 13 to be taken out of the vacuum environment, and a window driving mechanism 18 that moves the window 14 along with the movement of the X-ray illumination position by oscillating the window 14 in synchronization with the oscillation of the mirror 13. With this arrangement, the X rays coming from the window 14 pass through the X-ray mask 15 and fall upon the specimen 16 to replicate the mask pattern into the specimen.

摘要： In the manufacturing of a spiral pipe, there is first determined a maximum curvature which should be imparted to a strip of pipe forming material in order that a desired residual moment will be imparted to the finished pipe after the strip bent to the maximum curvature is allowed to spring back from the bent condition, which maximum curvature is determined based on the thickness, Young's modulus and yield stress of the strip, the desired curvature of the finished pipe, and the residual moment to be imparted to the finished pipe. By adjusting the position of three rows of forming rolls positioned at the apexes of a triangle, the flat strip is continuously bent into a spiral that has the thus determined maximum curvature. Then, the spirally formed strip is allowed to spring back toward its unbent shape to the diameter of the finished pipe, being stopped in the expansion due to the springback if it reaches the finished pipe diameter before completing springback or being expanded if it completes springback before it reaches the finished pipe diameter. Finally, the seam of the formed strip is welded when the strip is at the desired diameter of the finished pipe.
摘要翻译：在螺旋管的制造中，首先确定应该赋予管形成材料条的最大曲率，以便允许在弯曲到最大曲率的条带之后将成品管道赋予期望的剩余力矩从弯曲状态回弹，基于条的厚度，杨氏模量和屈服应力，成品管的期望曲率以及要施加到成品管的残余力矩来确定最大曲率。通过调整定位在三角形顶点的三排成形辊的位置，扁平条被连续弯曲成具有如此确定的最大曲率的螺旋形。然后，允许螺旋形成的条状物沿其未弯曲的形状弹回到成品管的直径，如果在完成回弹之前达到最终管直径，则由于回弹而在膨胀中停止，或者如果在弹回完成回弹之前膨胀达到成品管直径。最后，当带材处于成品管道的所需直径时，形成的带材的接缝被焊接。
