ABSTRACT:
A method capable of continuously manufacturing a metallic bent pipe having straight pipe portions at both ends of a bent pipe portion which have been subjected to the same heat treatment as that for the bent pipe portion. The method comprises the steps of: inserting the front end portion of a metallic pipe to be bent into a heating device, and advancing the pipe, with the travel of the heating device suspended, thereby to heat-treat the pipe; retracting the heating device and advancing the pipe to heat-treat the same; suspending the advance of the pipe while retracting the heating device thereby to heat-treat the pipe, and clamping the pipe by a bending operation part; suspending the retraction of the heating device and advancing the pipe as well as applying a bending moment to the pipe thereby to bend the same; suspending the advance of the pipe and heat-treating the same while retracting the heating device, and releasing the pipe from the bending operation part; retracting the heating device and advancing the pipe to heat-treat the same; and suspending the retraction of the heating device and moving the pipe to heat-treat the same.
