Claims

[Scope of utility model registration request]

(1) A joint structure formed by inserting and joining an inner-lined metal pipe into a socket-type metal pipe joint with a lining layer formed on the inner surface of the central part, the joint structure comprising a socket inner part of the pipe joint and the lining metal pipe. A sealing filler is filled into the annular groove-shaped gap formed between the tip and the tip of the insertion opening, and the filled portion is abutted from the inner side by a short tubular core.
Internal lining metal tube joint structure.

(2) Utility Model Registration Scope of Claim 1 In claim 1, an annular groove-shaped gap is filled with a hardening type filling adhesive held by a holding member, an inner lining metal pipe is entered into the annular gap, and A joint structure of inner-lined metal tubes, wherein the filling adhesive flows out from the holding member and oozes into the gap due to the entrance pressure.
