METHOD FOR ASSEMBLING PIPE GROUP OUTER TUBE, METHOD FOR ASSEMBLING STEAM GENERATOR, AND DEVICE FOR MOVING PIPE GROUP OUTER TUBE

摘要

With respect to a method for assembling a pipe group outer tube, a method for assembling a steam generator, and a device for moving a pipe group outer tube, in a method for assembling within a body part (41) a pipe group outer tube (44) supporting a heat-conducting pipe group (49), the body part (41) is formed with an upper body part (42) and a lower body part (43), and the pipe group outer tube (44), which is supported lying on its side, is inserted from the upper side of the lower body part (43) into the lower body part, which is supported lying on its side, and the pipe group outer tube (44) is moved to a prescribed insertion position and affixed to the lower body part (43). Thus, the operability of the assembly operation is improved.
