Abstract
PURPOSE: To obtain pipe materials having a uniform quality by efficiently and highly accurately processing weld beads when pipe materials are manufactured from strips, by rolling projected weld beads to thin films along the outer and inner peripheral surfaces of the pipe.
CONSTITUTION: A strip is curled to a cylindrical ring and both edges are welded to each other with a welding machine. Directly after the welding machine, an internal roller 6 and an external roller 8 are installed, and weld beads B projected from the inner and outer surfaces of the pipe material thus formed are pressed. The roller mechanism is built up in such a way that the internal roller 7 is composed of four barrel-shaped rollers 7aW7d contained in a housing 11 and sliding surfaces 10aW10d are formed by grinding at both sides of each roller. On the other hand, the external roller 8 is formed with four rollers 8aW 8d, and press the pipe material along its wall surface together with the internal roller 7. In this way, beads B projected from the inner and outer surfaces of the pipe material are rolled to thin films on the inner and outer surfaces.
