<p>PROBLEM TO BE SOLVED: To maintain a high degree of vacuum so as to remarkably reduce invading quantity of heat or discharging quantity of heat on the surface of a piping and prevent generation of excessive heat loss in a connecting part in a vacuum insulating and heat transporting piping transporting super low temperature fluid to high temperature fluid. SOLUTION: In this vacuum insulating body 40, a vacuum insulating body 10 in which a getter material and a radiation heat insulating material are filled between an inner cylinder and an outer cylinder, each of both the ends of the inner cylinder and both the ends of the outer cylinder is coupled with a recessed or projecting annular end plate and the inner cylinder and the outer cylinder are sealed and closed and the inside is made vacuum insulating layers is stuck to the outer peripheral part of an inner pipe 11 via a heat insulating adhesive material 13 after a plurality of vacuum insulating bodies 10 are fitted and connected, a vacuum insulating pipe 19 is constituted by fitting and holding an outer pipe 18 on the outer peripheral parts of these plurality of vacuum insulating bodies 10 via an air layer having a spacer, inner pipes each other of this vacuum insulating pipe 19 are successively welded and connected, a bisected vacuum insulating body 10 is fitted into the outer peripheral part of each of these connecting parts and a vacuum insulating body 7 in each vacuum insulating pipe 19 is connected by a recessed and projecting fitting via the heat insulating adhesive material 13.</p> |
