Abstract

PURPOSE: To reinforce the connection with the connecting flange without being affected by the wall thickness of the metal pipe by clamping the reversed portion of the metal pipe between the inner and outer peripheral walls in an annular groove of the connecting flange.
CONSTITUTION: The reversed portion 10 arranged at the end of a metal pipe 7 is pressed into an annular groove 4 arranged in the surface 3 on the connecting side of a connecting flange 1. At that time, an annular wall 6 formed between the annular groove 11 and a central through hole 2 is pushed to incline outwards so that the inner and outer peripheral walls in the annular groove 4 press on and clamp the reversed portion 10. In this way, it is possible to fixedly connect the metal pipe 7 with the connecting flange 1 without being affected by the wall thickness of the metal pipe 7. It is possible to connect more fixedly by forming the outer peripheral wall 15 of the annular groove 4 of the connecting flange 1 into a tapered shape so that the annular groove 4 becomes narrower toward the interior of the flange 1.
