Abstract
PURPOSE: The rigidly pipe setting tool capable of rigidly joining and setting the pipe easily, surely to the tube plate, by supplying the pressure liquid to the elastic bulging cylinder inserted into the pipe to cause bulging, and by causing the plastic deformation of the pipe by this bulging of the bulging cylinder.
CONSTITUTION: Under the condition that the pipe 2 is inserted into the tube plate 6, the fitting rod 3 is inserted into the pipe 2, and the superhigh pressure liquid, of 4,000W6,000kg/cm2G for example, is supplied from the unillustrated superhigh pressure generator to the liquid pathway 1. Hereby, the superhigh pressure liquid is fed into the inner surface of the bulging cylinder 4 and this liquid pressure causes the elastic deformation of the bulging cylinder 4 which is then bulged. Accordingly, by this bulging of the bulging cylinder 4, the pipe 2 causes plastic deformation and bulges, so that the pipe 2 is tightly pressure welded to the tube plate 6 and is surely, rigidly set. Next, the operation of the superhigh pressure generator is stopped, and the superhigh pressure liquid of the inside 7 of the pathway 1 is released to contract the bulging cylinder 4, and then, the fitting rod 3 is pulled out of the pipe 2. Besides, the generation of outer gap 19 is prevented by the specified clamping cylinders 5, 5', installed on both sides of the bulging cylinder 4, and hereby, the bite-off damage of the bulging cylinder 4 is obstructed.
