Abstract

PURPOSE: To swell out the branch part of a pipe without reducing its thickness and to improve the product quality, by pressing the extended parts of the steel plate having extended breadths at its both sides by necessary amount of the swelling out of the branch pipe for the pipe joints.
CONSTITUTION: A steel plate 12 is formed to a semicircular shape except its extended parts 14. And the edges 22 of both the extended sides 14 of a semicircular formed body 15 is applied a force by a working surface 20 of a compressing tool 18, which presses at a breadth δ of the extended part 14 downward of the formed piece 15. Then by the lowering of both the extended sides 14 and by the constraining of die surfaces 23, it is pressed from both sides to its peripheral direction. And a heated shell part 16 seeks its direction to relieve the pressure and swells out of a relieving hole 24 to form a predetermined part for a branch pipe. Then the branch pipe side piece thus obtained is machined and finished and connected to the nonbranch side piece thus making a T-joint.
