性、耐久性が低下しやすい。(Prior Art) Conventionally, when there is a pillar 5 between a pipe 3 and a pipe 4 when piping is installed between a faucet 1 and a water supply fixture 2 as shown in FIG. 7. Prepare a pipe 10.11.12 of a predetermined length connecting between 8.9 and each elbow, provide an expansion s13 (flare) at the end of the pipe 3 with an end processing tool, and insert the left end of the elbow there. They are joined by insertion and brazing, and each elbow is connected to the adjacent pipe in the same way. However, in this case, a large number of parts are required, and the connection work is time-consuming, which not only increases costs, but also increases the number of connection points, which increases the risk of leakage and tends to reduce reliability and durability.

。(Example) Fig. 1 and Fig. 2 both show pipe joints of different sizes according to the present invention. section 17 and five spiral groove-formed flexible sections 18 between adjacent straight pipe sections. To make such a pipe joint 15, a spiral groove-formed flexible portion 18 is formed by intermittently applying a spiral flexible process to a pipe made of, for example, Cu (copper), SUS (stainless steel), or Ti (titanium). The nominal diameter of the pipe material is, for example, 1/2 inch, 5/8
inch, 3/4 inch (outer diameter), wall thickness is e.g. 0°5m
In l+, the straight pipe portions 16 and 17 cannot be bent at the piping site, but the wall thickness is selected to be such that it is possible to perform flaring to form an outward flange or expanded portion at the end. In addition, the flexible part 18 in the middle can be bent by placing it against the corner of the pillar and pressing both sides against the pillar by hand. It is provided with appropriate flexibility so that it can be moved.

に裁断されている。When the outer diameter of the material pipe is 3/4 inch, the depth Ll of the spiral groove and the pitch 2 are, for example, Ll = 1-5am+-1
2=7jw+, and in the embodiment of FIG. 1, the flexibility F! The length L3 of $18 and the length L4 of the straight pipe part 17 between the adjacent flexible parts 81 are:
For example, L3=130jI1. It can be L4-75 shoes. In the case of Figure 2, L3-55a*1L
4 = 55am, and the total length L5 is both cut to 15 = 1000mm.

５を分岐させることができる。When using the pipe joint according to the present invention, a cap nut 20 is previously fitted to the straight pipe portion 16 at the tip as shown in FIG. 5, and then an outward flange 21 can be provided by flaring. In that case, the outlet screw portion 23 of the hot water supply device 22
can be connected to. Also, as shown in Fig. 6, cut the straight pipe part 1 in the middle, attach the cheese 24, and connect another pipe 2.
5 can be branched.
