もある。2. Description of the Related Art A conventional sprinkler head mounting pipe is a main pipe 1 arranged on a ceiling while avoiding a pillar P as shown in FIG.
A plurality of branch pipes 2 are branched in a cross shape, a plurality of small branch pipes 3 are branched in a T shape from each branch pipe 2, and a sprinkler head 4 is attached to the small branch pipes 3. Further, recently, in order to reduce the number of parts of the sprinkler head mounting pipe, a large number of branch pipes 2 are branched in a cross shape from the main pipe 1 as shown in FIG. The multi-port joint 5 is attached, and the flexible pipe 6 is attached to the distribution-type multi-port joint 5.
There is also one in which a required number of are attached, and the sprinkler head 4 is attached to the tip of the flexible tube 6 to be arranged at a required position.

The grade 9 is fitted on the outside and both ends thereof are joined to the end pipes 7, 7 ', and the collar 10 is fitted on the outside of the both ends and welded to the end pipes 7, 7'. The flexible tube 6 having such a structure can prevent axial expansion of the bellows 8 due to internal pressure and prevent external damage to the bellows 8. However, the bellows 8 cannot be inspected for leakage or appearance. The corrosion, weld defects, etc. cannot be investigated, the deformation of the bellows 8 cannot be controlled, and the degree of deformation cannot be inspected.
