PROBLEM TO BE SOLVED: To provide a pipe joint with which there is no failure in generating vibrations of a tube or a heat exchanger to which a tube is connected during a device operation.SOLUTION: In a pipe joint 10, an opposite-side member 6 includes a male screw screwed with a female screw 4a of a nut 4. A collar part 1a is fastened between the bottom surface of the nut 4 and the opposite-side member 6 by screwing the female screw 4a with the male screw. A pipe body inner circumferential member 1 has a first end surface 1c and a second end surface 1d, which are two axially faced end surfaces. An outer diameter Dof the first end surface 1c and an outer diameter Dof the second end surface 1d are the same. |
