DOUBLE CONDUIT PIPING USED IN HOT WATER SUPPLY PIPING SYSTEM AND THE LIKE

摘要

PROBLEM TO BE SOLVED: To provide double conduit piping used in a hot water supply piping system and the like superior in piping workability by being easily bent in any direction by improving the cross-sectional shape of a partitioning wall of the double conduit piping comprising two fluid pipe conduits independent from each other by disposing the partitioning wall inside, while integrated as a whole.

SOLUTION: In this double conduit piping constituted by partitioning the inside of a pipe into the first fluid pipe conduit 16 and the second fluid pipe conduit 17 by the partitioning wall 15 continued in the pipe axial direction, the partitioning wall 15 has the S-shaped cross section.
