CRANE® CRYOGENICS Vacuum Jacketed Rigid Piping
CRANE® CRYOGENICS Vacuum Jacketed Rigid Piping (VJP) is a double-walled piping system with a vacuum space between the inner and outer pipes. This vacuum space acts as a thermal barrier that reduces heat transfer and prevents product boil-off, minimizing product loss and ensuring safety and quality. VJP offers a number of significant advantages over conventional piping systems for liquid cryogenic media.
