DECOMPRESSION HEAT-INSULATING PIPE STRUCTURE
First Claim
1. A decompression heat-insulating pipe structure comprising an outer tube and an inner tube each having a flange;
- and a seal member between the flanges, the seal member being configured to keep a space between the outer tube and the inner tube in a decompression state, further comprising;
a shifting means configured to shift the outer tube and the inner tube relatively so as to selectively dispose the tubes at a sandwiching position to sandwich the seal member between the flanges and at a cancellation position to cancel sandwiching of the seal member.

Abstract
Provided is a decompression heat-insulating pipe structure that can be used in the system operating at high temperatures. A decompression heat-insulating pipe structure of the present disclosure includes: an outer tube and an inner tube each having a flange; and a seal member between the flanges, the seal member being configured to keep a space between the outer tube and the inner tube in a decompression state, and a shifting means configured to shift the outer tube and the inner tube relatively so as to selectively dispose the tubes at a pressing position to press the seal member between the flanges and at a cancellation position to cancel the pressing of the seal member.
