Abstract
A cryogenic material transfer system incorporates a pipe-in-pipe configuration with a nanoporous or microporous insulating layer filling the annulus between the inner and outer pipe. The insulating layer is of sufficient flexibility to absorb and expansion or contraction of the inner pipe due to the flow of cryogenic material therethrough. For longer transfer systems a bulkhead is provided between adjacent pipe joints. Intermediately of the pipe joints an additional bulkhead may be employed to provide additional sealing or water stops and for providing provide additional load transfer. A fiber optic sensor system is installed in the annuals between the inner and outer pipe.
Claims30
A cryogenic material transfer system, comprising:
- a. a plurality of rigid outer pipe pipes each of predetermined length and in end-to-end relationship;
- b. a plurality of rigid inner pipes inside the outer pipes and each of a predetermined length substantially the same as the predetermined length of the corresponding rigid outer pipe;
- c. a bulkhead between and providing a coupling for adjacent ends of pipe lengths;
- d. a transition for receiving two adjacent pipe ends at the bulkhead;
- e. a split sleeve positioned between the two pipe ends and held in position by the transition;
- and
- f. an insulating layer filling the annulus between the inner and outer pipe of sufficient flexibility to absorb and expansion or contraction of the inner pipe due to the flow of cryogenic material therethrough.
