Made of synthetic resin such as vinyl chloride resin and polyethylene,
A large number of annular ribs 2 are provided at predetermined intervals on the outer peripheral surface of the pipe. Although not shown, a spiral rib may be provided instead of the annular rib 2. Cylindrical short pipes 3 are provided at appropriate places on the outer peripheral surface of the synthetic resin pipe 1 with ribs. The cylindrical short pipe 3 is for attaching the branch pipe 4 to the synthetic resin pipe 1 with ribs, and has an inner diameter substantially equal to the outer shape of the branch pipe 4 so that the two cylindrical short pipes 3 are concentric. And
In the illustrated example, a rib-shaped synthetic resin pipe 1 is provided in a plurality of locations in a staggered manner. Although not shown, two or more cylindrical short pipes may be provided concentrically and linearly at a plurality of locations of the ribbed synthetic resin pipe.
