する合成樹脂で形成するのが好ましい。As shown in FIGS. 1 and 2, a branch pipe joint 1 of the present invention comprises a saddle portion 2 and a short pipe portion 3 made of a thermoplastic synthetic resin, for example, polyethylene, and the saddle portion 2 is made of a thermoplastic synthetic resin. The outer surface of the pipe 4 in the radial direction is covered and fusion-fixed, a through hole 5 is bored in the pipe 4, and a branch pipe (not shown) is connected to the short pipe portion 3. The pipe 4 is made of polyethylene, for example, and is buried in the ground for transporting city gas and the like. The saddle portion 2 of the branch pipe joint 1 has a substantially semicircular shape on the front side, and the heating wire 6 is embedded at a predetermined interval on the inner surface side thereof. Further, sockets 7 are provided so as to project on both sides of the short pipe portion 3 on the outer surface of the saddle portion 2, and a connector 8 is connected to each socket 7. The saddle part 2
In the place where the heating wire 6 is not embedded, the rod-shaped indicator 9 is provided so as to penetrate therethrough, and the lower end portion thereof projects to the inner surface of the saddle portion 2. In the drawing, thin-walled portions 10 are formed on both ends of the saddle portion 2 in which the heating wire 6 is not embedded, and the lower end portion of the rod-shaped indicator 9 is attached to the thin-walled portion 10.
The rod-shaped indicator 9 is provided as an example so that the upper end of the rod-shaped indicator 9 is projected to the outer surface of the saddle portion 2. This stick indicator 9
Is preferably made of, for example, a metal or a synthetic resin having a melting point higher than that of the saddle portion 2.
