Since the edge of the large-diameter tube is drawn using a second mold whose central axes match those of the first mold, it is possible to easily align the central axes of the large-diameter tube and the small-diameter tube, and it is possible to draw the end edge of the large-diameter tube with ease. There is no need to weld rings to small diameter pipes, reducing the number of welded parts.
It does not take much time to manufacture.
