する危険性を生ずる。2. Description of the Related Art As a conventional method for lining the inner surface of a pipe, a hard tube having a smaller diameter than that of the tube is inserted over the entire length of the tube, and then the tube is heated and pressurized from the inside to expand and line the inner surface of the tube. A method of doing so has been proposed.
In the hard tube lining formed by applying this expansion method, a gap is inevitably formed between the tube and the tube due to thermal contraction that occurs after the heating and pressurizing expansion. Therefore, if a water faucet is bored in such an inner hard tube lining pipe, the water faucet and the gap will communicate with each other. There is a risk of water leakage.

The stepped portion (5) and the portion having a smaller inner diameter therebelow are expanded, and by the expansion of the core (1),
A rubber cylinder (6) fitted and held on the outer peripheral portion of the core (1) is strongly attached to the inner peripheral surface of the pipe (a) and the water diversion port (b) of the hard tube lining (a 1 ) on the inner surface thereof. It is pressed and crimped. Therefore, the gap (a 2 ) between the pipe (a) and the lining (a 1 ) is sealed by the rubber tube (6).

This annular protrusion (3 ') is the lower end edge of the diversion tap (b).
Then, the inner surface of the hard tube lining (a 1 ) is locked and the core (1) is prevented from pulling out upward. Therefore, as shown in FIG. 5 (c), the core (1) and, by extension, the seal member (A) are prevented from being pulled out in the up and down directions in the water faucet (b), so that a stable and secure fitting and fixing state is achieved. can get.
