なかった。Conventionally, galvanized iron plates, colored iron plates,
Exterior covers such as aluminum plates and plastic plates were not required to have the function of absorbing the expansion and contraction of piping and insulation materials that occur during operation, or the function of maintaining airtightness, in order to prevent external damage and provide weather resistance.

ー１を連結・密着させる。This will be explained below with reference to embodiment figures. 1, 2, and 3 are schematic diagrams showing the relationship between the heat insulating cylinder 8 covered with the moisture-proof layer 9, the expansion joint 5, and the exterior cover 1. For example, in order to absorb shrinkage in the axial direction of the piping 6 and the heat insulating cylinder 8 when low-temperature fluid passes through the inside of the piping, the moisture-proof layer 9
The exterior cover 1 formed in a roll shape is attached to the outer periphery of the exterior cover 1 and connected and tightly attached to both sides of the exterior cover 1.

−１内部の気密が保持される。Next, for example, if the outer circumference of the Frethane cylinder is expected to shrink by about 10 am and the diameter by about 3 m, the cushioning material with a thickness of 1Qm is compressed to a thickness of about Σ, and the outer cover is tightly tied and tightly attached. As the heat insulating tube 8 contracts in the circumferential direction, the cushioning material 3 restores its original shape and the interior of the exterior cover 1 is kept airtight.

411. Apply double-sided adhesive tape 2 to the overlapped part, and connect the expansion joint 5.
After being attached to both outer sides of the body, the outer periphery of both ends is tied tightly with bands 11.
クッション材３としては無機質で復元力あり、低温又は
高温に耐える素材が開発されている。As the cushioning material 3, materials have been developed that are inorganic, have resilience, and can withstand low or high temperatures.

が好ましい。The material for the expansion joint 5 may be a plastic that is closest to metal, such as ultra-high molecular weight polyethylene, and it is preferable to laminate an acrylic film on the surface. Alternatively, an aluminum plate or the like may be used. The material for the exterior cover 1 is preferably an acrylic film laminated steel plate.
