Abstract: A cryogenic seal for vacuum-insulated pipe systems where the pipe system includes an inner pipe connected to an outer pipe by a bellows. The seal prevents cryogenic liquid from leaking from the inner pipe into the annular vacuum space between the inner and outer pipes in the event of bellows failure. One end of the bellows is connected to the inner pipe by a movable bellows ring and the other end of the bellows is attached to the outer pipe by a fixed bellows ring. A bellows guide is attached to the fixed bellows ring and receives the movable bellows ring in a sliding fashion. The seal may be positioned between the movable bellows ring and the bellows guide or between the fixed bellows ring and the outer surface of the inner pipe. The seal may also be positioned between the bellows shield and the movable bellows ring. The seal may be a leak control ring or the packed gland type.
