摘要： An apparatus for heat-treating pipes comprising a furnace chamber for accommodating a plurality of pipes as arranged in parallel, a chain conveyor disposed in the furnace chamber for transporting the pipes in a direction at right angles to the axes of the pipes, and a plurality of stopper means for stopping the pipes intermittently at suitably spaced-apart positions in the path of transport by the chain conveyor and causing each of the pipes to rotate about its own axis in cooperation with the chain conveyor. Since the pipe is intermittently stopped and rotated about its own axis during heat treatment, the pipe is free of thermal deformation to an elliptical shape. Pipes can be heat-treated in succession in a small space, therefore with a very high efficiency. The motion of the chain conveyor is utilized for rotating the pipe without necessitating any additional device for the rotation.
