PROBLEM TO BE SOLVED: To provide a cooling transfer hose usable in a marine environment.SOLUTION: The cooling transfer hose for hydrocarbon includes an inner hose 52, an outer hose 53 installed concentrically to surround the inner hose 52, and spacer members 55, 56, 57 for burying an annular gap between the inner hose 52 and the outer hose 53. A fibrous heat insulating material 54 forms three-dimensional matrix included within the annular gap, the outer hose 53 includes a rubber elastic and/or plastic material, and the fibrous material is continuous through an almost all part of a hose having the inner hose 52 and the outer hose 53, and forms the spacer members 55, 56, 57.

PROBLEM TO BE SOLVED: To suppress swelling of a heat insulating material coating a projection pipe part, to the outward in the pipe diameter direction, while securing approximately equivalent heat insulating performance to an ordinary pipe part, in the projection pipe part. SOLUTION: In this pipe heat insulation structure wherein a pipe A equipped with a projection part 2 projecting outward in the pipe diametral direction furthermore than the pipe 1 outer surface is coated with a heat insulating material 3, the projection pipe part 6 including the projection part is coated with a vacuum heat insulating material layer 7, and each ordinary pipe part 9 on both sides sandwiching the projection pipe part is coated with a non-vacuum heat insulating material layer 10.
