Abstract
PURPOSE: To make the device simpler and working time shorter by fetching the pressure signal below the set value for each of pipes, and detecting and displaying the end of the pipe expanding through comparison of the same with the holding- time completion signal of the set pressure, in press-welding the multiple pipes simultaneously to a pipe plate.
CONSTITUTION: In expanding, sealing and sticking a plurality of pipes 11a... to a pipe plate 8 by high-pressure fluid, the pipe expanding devices consisting of automatic on-off valve devices B and sealing devices A for pipe expansion are inserted into the a plurality of pipes 11a... inserted into the pipe plate 8, and the pipes are expanded and sealed by the high-pressure fluid through a high-pressure generating device 12, a boosting device 14 and branch pipes aWd. At this time, the signal of a pressure S below the set pressure P is fetched for each of the pipes and upon arriving of the fluid pressure at the set pressure P, the pressure is held for a fixed time t1 by a timer or the like, after which the signal is sent at the point Q and the completion of the pipe expanding is displayed by a pilot lamp 21. This method permits simultaneous completion of the press-welding of an extremely large number pipes to a pipe plate.
