Abstract

PURPOSE: To increase the strength of pipe and closing, an open end of piping is compressed to form thick wall of a desired length, the thick wall is then squeezed into a closed end.
CONSTITUTION: A mandrel 11 having a recess 10 at its end is inserted into a pipe 12, and is fixed by a chuck 13. A fixture 15 for compressing is provided having the same diameter as the outer diameter of the pipe 12 and having a protrusion 14 with a diameter smaller than the inner diameter of the pipe 12 and an engaging point with the recess 10. The fixture 15 is inserted into the chuck 13 and pressed toward the mandrel 11 by using a hydraulic cylinder or the like. This compression causes an open end 16 of the pipe 12 to form a thick wall 17 of the desired length. The thus forming pipe 12 is supported between a chuck 20 and a mandrel 19 having a mirrored round edge 18. Then, the pipe 12 is rotated, while a spatula 21 is contactingly pressed against the pipe 12 in the arrow directions, thereby to form a closed portion 22. The formed pinhole 23 is brazed and sealed.
