Abstract

PURPOSE: To attain pipe junction having required joining intensity simply and reliably without need of special technique in such a way that a telescopic method is applied for the large diametral part formed on each pipe extremity, which are tightly fastened by contracted deformation.
CONSTITUTION: In the first place, at the same time as a large outer diametral part 2 is expandingly formed at a joining extremity 1 a of a pipe on one side, a large inner diametral part 4 is formed to have equal inner diameter to the outer diameter of said large outer diametral part 2 at a joining extremity 3a of a pipe 3 on the other side. Secondly, a joggled part 14 of the pipe 3 is insertedly brought into contact with a surface 15a of a die 15, the large outer diametral part 2 of the pipe 1 is inserted into the large inner diametral part 4 of the pipe 3 in this condition. And it is tightly fastened in the procedures of plastic deformation in such a way that a piston 8 is put to make contracted action in the condition that the large outer diametral part 2 of the pipe 1 is brougth to be fully inserted into the large inner diametral part 4 of the pipe 3, an extremity 4a at the large inner diametral part of the pipe 3 is contracted along the outer figuration of a joggled part 5 of the pipe 1.
