空断熱されている。[Background of the Invention] An example of conventional vacuum insulation piping will be explained with reference to FIG. FIG. 1 is a vertical cross-sectional view of a conventional vacuum insulation piping in which an inner pipe is wrapped with a laminated insulation material made by laminating a large number of radiation shielding materials and spacers alternately. The laminated heat insulating material 12 is wrapped around the inner tube 13 except for the part where the inner tube 13 and the outer tube 14 are connected to each other.
1 are arranged concentrically. Further, a space 15 formed by the laminated heat insulating material 12 and the outer tube 14 is vacuum insulated.
外管１４の外部と真空断熱され、積層断熱材１
２により輻射熱の侵入を抑制された内管１３を極
低温物質が流通し移送される。 The laminated insulation material 1 is vacuum insulated from the outside of the outer tube 14.
2, the cryogenic material flows and is transferred through the inner tube 13 in which the penetration of radiant heat is suppressed.
このような真空断熱配管では、次のような欠点

The present invention provides vacuum insulated piping with an inner pipe in which a laminated insulating material is continuously wrapped around the outer periphery and a cryogenic substance is circulated and transferred therein, and a vacuum insulated space is formed with the laminated insulating material to form a vacuum insulated space in the inner pipe. an outer tube disposed concentrically on the outside of the holder, a holder ring disposed within the vacuum insulation space, and support for the inner tube radially to the holder ring and via the laminated heat insulating material. The support includes a support that is provided so that the end position and the support end position of the outer tube can be adjusted and supports the inner tube and the outer tube in the radial direction while holding the vacuum insulation space through the laminated heat insulating material. By wrapping the laminated insulation material around the outer circumference of the inner pipe without interruption, the work efficiency of wrapping the laminated insulation material is prevented from decreasing, and the number of man-hours required for wrapping the laminated insulation material around the inner pipe is reduced. By preventing direct contact of the support with the inner tube, heat flow to the inner tube through the support is suppressed, reducing the amount of heat entering the inner tube, and the support is attached to the holder ring to support it. By providing an adjustable end position, it is possible to facilitate the installation work of the inner tube wrapped with the laminated heat insulating material and the outer tube.

A holder ring 16 is arranged inside. The holder ring 16 is tubular in shape, and its length is the minimum length necessary to provide the support 11'. The shape of the support 11' is rod-like, and in this case, three supports 11' are arranged at an angle.
The shafts are arranged radially on the holder ring 16 at intervals of 120 degrees so that their axes substantially coincide with the center of the holder ring 16. The support 11' is provided to the holder ring 16 by passing through the holder ring 16 and being screwed in the middle thereof. In this case, the inner end of the support 11' with respect to the holder ring 16 becomes the supporting end of the inner tube 13 via the laminated heat insulating material 12,
The outer end of the support 11' serves as the supporting end of the outer tube 14. Further, the positions of these supporting ends can be adjusted by screwing the support 11' onto the holder ring 16. The arrangement of the inner tube 13 and the outer tube 14 wrapped with the laminated heat insulating material 12 is carried out as follows. First, the holder ring 16 provided with the support 11' is disposed outside the inner tube 13 around which the laminated heat insulating material 12 is wound. At this time, each inner end of the support 11' is brought into contact with the outer periphery of the laminated heat insulating material 12 with its position adjusted appropriately. In this state, the outer tube 14 is placed outside the inner tube 13, but at this time, the outer ends of the supports 11' are positioned at positions that do not obstruct the installation work of the outer tube 14. adjusted. With this arrangement, the inner pipe 13 wrapped with the laminated heat insulating material 12
The outer tube 14 is supported in the radial direction by a support 11' while maintaining a vacuum insulation space 15.

を容易化できる。 In vacuum insulated piping like this example, the inner pipe is not provided with any support, so the amount of heat intrusion into the inner pipe can be suppressed to a small level, and the laminated insulation material can be wrapped around the inner pipe without interruption, so the laminated insulation The workability of wrapping the material is improved and the number of man-hours required for wrapping the material can be reduced. In addition, since the support end position of the support can be adjusted,
The installation work of the inner pipe and outer pipe wrapped with laminated heat insulating material can be facilitated.
