<p><P>PROBLEM TO BE SOLVED: To provide a cryogenic fluid transfer tube capable of being handled easily and safely even by one person because the tube is very lightweight and flexible irrespective of improvement in conductance, and being produced at low cost. <P>SOLUTION: The flexible cryogenic fluid transfer tube 1 performs heat insulation by forming a vacuum space 4 between an inner tube 2 and an outer tube 3. The cryogenic fluid transfer tube 1 comprises the inner tube 2 made of metal and the outer tube 3 made of predetermined low-volatile resin. The vacuum space 4 is formed between the inner tube 2 and the outer tube 3 by passing a cryogenic fluid through the inner tube 2. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
