Cryogenic piping system

A method for improving the insulation characteristics of a cryogenic piping system wherein an insulation volume defined by a jacket coaxial to an inner pipe is evacuated to a moderate vacuum and then filled with a condensable gas in one or more evacuation and filling cycles, and then, after evacuati...

Summary:A method for improving the insulation characteristics of a cryogenic piping system wherein an insulation volume defined by a jacket coaxial to an inner pipe is evacuated to a moderate vacuum and then filled with a condensable gas in one or more evacuation and filling cycles, and then, after evacuation to a moderate vacuum, the condensable gas is condensed to effect a high vacuum within the insulation volume.
