Claims

[Scope of utility model registration request]

A screw-in structure that allows multiple anti-corrosion pipe bodies coated with an anti-corrosion layer to be threadedly connected to the main body of the pipe joint whose outer peripheral surface is covered with anti-corrosion sleeves made of synthetic resin that extend outward from both ends. In the anti-corrosion pipe fitting, an elastic ring having a substantially rectangular cross section and flat in the axial direction is fitted onto the uncoated outer circumferential surface of each of the outer sheath layers of the plurality of pipe bodies, and this ring is inserted into the outer circumferential surface of each of the plurality of pipe bodies, which is flat in the axial direction. Compressed by a plurality of stepped portions formed on the inner circumferential surfaces of both ends and an uncoated outer circumferential surface of the outer coating layer of the anticorrosive pipe body, including a tapered portion formed at the peeled end of the outer coating layer. A threaded type anti-corrosion pipe joint, characterized in that a gap created between the anti-corrosion sleeve and the anti-corrosion pipe body is hermetically sealed.
