継手。[Claims for Utility Model Registration] 1. The inner surface of a metal pipe joint having a female thread at the end is covered with a synthetic resin layer except for the female thread, and a synthetic resin tube is attached from the synthetic resin layer to the end side. A PVC-lined steel pipe whose inner surface is lined with a PVC resin pipe or a polyethylene powder lined with a polyethylene powder resin is provided between the cylindrical member and the female thread. In a pipe joint provided with a pipe insertion part for accommodating the inner and outer surfaces of a lined steel pipe, the outer diameter of the cylindrical part is set to a diameter between the inner diameter of the PVC-lined steel pipe and the inner diameter of the poly powder-lined steel pipe, and A corrosion-resistant pipe joint characterized in that an annular rubber gasket having a wedge-shaped cross section facing toward insertion into the gap between the inner surface of the connecting pipe and the outer surface of the cylindrical body is attached to the outer surface of the end of the cylindrical body. 2 Utility Model Registration Claim 1 of the claims, wherein the end side of the rubber gasket has a wedge-shaped cross section facing toward the side where it is inserted into the gap between the inner surface of the connecting tube and the outer surface of the cylindrical body, and the other side thereof is wedge-shaped. A corrosion-resistant pipe joint characterized by being provided with an extension part that comes into contact with the back wall of the insertion part.
