Claims

[Scope of utility model registration request]

In a joint in which the socket of a steel pipe whose inner surface is coated with resin is inserted into the socket of a water supply/drainage port pipe, and the socket and the socket are tightened with a press ring through an annular packing made of an elastic member, the socket and the socket are Between the socket and the socket, an annular packing extends along the outer circumference of the steel pipe to the tip to form a cylindrical part, and the end of the cylindrical part is bent inward to cover the end face of the steel pipe, and a circular seal is formed at the inner corner of the bend. An annular groove is formed, the bent end is made thicker in the longitudinal direction of the steel pipe, and the inner circumferential surface tapers to a larger diameter gradually toward the tip, and the outer circumferential surface is made to have a smaller diameter than the inner circumference of the socket. 1. A pipe joint structure, characterized in that the tip is formed on a cylindrical surface, the annular groove is filled with an anticorrosive adhesive, and the tip is pressed into contact with the socket step of a water supply/drainage port pipe.
