Claims

[Scope of utility model registration request]

A pipe with a structure in which the end of a joint pipe is inserted into a joint body with a male thread carved on the outer circumferential surface of the socket, a tightening ring is inserted into the end of the joint pipe, and a union nut is tightened by engaging the male thread and screw. In the joint, the tightening ring is made of a harder material than the joining pipe, and either a pressing surface that transmits the pressing force of the union nut to the tightening ring or a pressing surface that transmits the reaction force from the joint body to the tightening ring. Alternatively, both of the tightening rings are formed into a tapered surface shape that generates a pressing force component in the direction of diameter reduction, and a seal ring is further provided between the outer circumferential surface of the joint pipe near the tip and the inner circumferential surface of the socket of the joint body. A pipe joint characterized by an intervening joint.
