Abstract
PURPOSE: To obtain a double flanged pipe through a plastic molding of a second flange section by clamping a single-flanged pipe with a pressing mandrel and an external molding roller heating the upper end thereof by a burner being turned as placed on a table horizontally rotatable.
CONSTITUTION: A single-flanged pipe 1 is placed on a table 2 horizontally rotatable with the flange 1a downward. The pipe 1 is grasped between a plurality of side support rollers 3 turning in contact with the outer surface of the pipe middle part, an external molding roller 4 rotating in contact with the outer surface of the pipe upper end while having a truncated-cone-shaped roll surface and a press roller 5 rotating in contact with the pipe upper end. Then, the upper end of the pipe is heated above the recrystalization temperature with a burner 6 turning thereof, while a pressing mandrel 7 having an inverted truncated-cone-shaped periphery is provided properly eccentric with the pipe and turned against the inner surface of the pipe upper end. In this manner, the second flange 8 is plastically molded.
