PURPOSE: An apparatus for forming pipe connection part is provided which improves stiffness of the pipe and solidly connects the pipe to the other pipe by integrally forming a connection part of pipe and flange. CONSTITUTION: The apparatus comprises a pipe supporting implement for fixing a pipe; a high frequency heating device for heating one side of the pipe; an upper die(31) on which an upper pipe receiving part(33) for supporting the outer surface of the pipe is formed, and in which an upper connection part receiving groove(35) for forming a connection part of the pipe is continuously formed on a front part of the upper pipe receiving part; a lower die(32) on which a lower pipe receiving part(34) for supporting the outer surface of the pipe by forming a cylindrical groove as a whole along with the upper pipe receiving part of the upper die is formed, and in which a lower connection part receiving groove(36) for forming a connection part of the pipe along with the upper connection part receiving groove is continuously formed on a front part of the lower pipe receiving part; a punch(40) for forming a connection part of the pipe by coming in and out of the connection part receiving grooves(35,36) of the die(30); and a press device(50) for moving the pressed punch by pressing the punch in a longitudinal direction of the pipe.
