Double pipe



【課題】この発明は、流路長を確保しつつ、所定の配管スペース内に収まるように配管することができる2重管の提供を目的とする。 【解決手段】例えば流路長が4mの2重管1を、幅204mm、長さ440mm、高さ61mmに形成された容器10に収容する場合、内管2と外管3とからなる1本の2重管1を、蛇行方向Eに蛇行及び折り返して蛇行部6A〜6Dを形成する。その蛇行部6A〜6Dを、重ね合わせ方向Gに対し層状に配管して層状蛇行部7Aを形成した後、2重管1の蛇行部6A〜6Dを層状に配管してなる層状蛇行部7Aを容器10に収容する。これにより、2重管1の流路長を確保しつつ、所定の配管スペースを有する容器10の内部に収まるように収容することができる。 【選択図】図8
PROBLEM TO BE SOLVED: To provide a double pipe that can be laid so as to be settled within a predetermined piping space while securing a flow passage length.SOLUTION: For example, when the double pipe 1 having the flow passage length of 4 m is housed in a container 10 formed to have width of 204 mm, length of 440 mm and height of 61 mm, one double pipe 1 comprising an inner pipe 2 and an outer pipe 3 is made to meander in a meandering direction E and turn to form meandering parts 6A to 6D. After piping of the meandering parts 6A to 6D is made in a layered shape with respect to an overlapping direction G to form a layered meandering part 7A, the layered meandering part 7A formed by piping the meandering parts 6A to 6D of the double pipe 1 in the layered shape is housed in the container 10. Thereby, the double pipe 1 can be housed so as to be settled within the container 10 having a predetermined piping space while securing the flow passage length of the double pipe 1.
