Claims

[Scope of utility model registration request]

A pipe joint that is externally fitted onto the headless pipe A at the joint between the headless pipe A and the flange pipe B, which has a flange portion 4 erected on the end 3 facing the end 2 of the headless pipe A. In the joint fitting for preventing separation of the flange pipe B, a bulging part 16 is integrally formed on the fitting main body 1 having a flange part 8 facing the flange part 4 of the flange pipe B, and the inside of the bulging part 16 is The headless tube A
A retaining mechanism 6 is provided for press-welding the outer circumferential surfaces of the pipe, and the inner circumferential surface 11 of the fitting main body 1 immediately below the flange portion 8, the outer circumferential surface IC on the end 2 side of the headless pipe A, and the flange pipe 5. A housing 12 for accommodating the packing 7 is formed between the end face 5C of the flange pipe B and the flange part 4.8 of the fitting body 1, and the flange parts 4.8 of the flange pipe B and the fitting body 1 are tightened to draw each other together. A joint fitting for preventing detachment of a pipe joint portion, characterized in that it is constructed so that when the headless pipe B is brought to the side of the headless pipe A and joined, the packing 7 is pressure-sealed to each wall surface of the housing 12.
