Abstract: In the present invention, a pipe joint has housing parts as a housing obtained by dividing the housing into three parts in a circumferential direction. The first housing part has connecting parts. The second, third housing parts have connecting parts, respectively. Connecting parts are provided to be detachably mutually connected by fastening with tightening members, at end parts protruding outward from vicinities of an inner peripheral surface with a sealing member arranged in sides opposite to sides of the first housing part.

Abstract: This pipe joint comprises a hollow cylindrical joint body made of elastic material such as heat-resistant rubber with a prescribed length, and a circular flange for connecting piping attached to the both sides of the joint body, on the side of the inner circumference of the joint body is provided a bellows metal pipe closely contacted with the joint body, and the thickness of the joint body is at least larger than the size of the summit or the trough of bellows of the metal pipe.
