Claims

[Scope of utility model registration request]

A spherical sealing material is interposed between one side flange provided at the end of one exhaust pipe and the other side flange provided at the other end of the exhaust pipe, and the spherical seal material is interposed between the one side flange and the other side flange. In a spherical pipe joint in which the spherical sealing material side spherical part is pressed against the inner surface of the flange side spherical part of the one side flange by narrowing the interval, the other side flange is placed on the other side flange side of the spherical sealing material. The spherical cover is formed along the outer periphery of the formed flat part, and the other side inner periphery of the spherical cover, one side of which is the cover spherical part, is screwed onto the outer periphery of the other side flange. A spherical pipe joint characterized in that a spherical part is engaged with an outer periphery of the flange side spherical part.
