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 via an annular packing, there is a gap between the socket and the socket. The annular packing extends to the tip of the steel pipe to form a cylindrical part, and further extends in the direction of the cylinder center axis at the end of the cylindrical part to form a hollow disc part, and the inner surface of the hollow disc part is covered with the resin of the steel pipe. A pipe joint structure characterized by adhesion to the end face of the covering part.
