Quality Cryogenics Vacuum Jacketed Pipe Bayonet Adapter**Unit in Box, ready to use. Single unit in Open box with instructions for installation. See photos for further details.Vacuum Jacketed Pipe is the preferred choice for the safe, reliable, and cost-effective transfer of cryogenic liquids including liquid nitrogen, oxygen, argon, helium, hydrogen and natural gas. The VJP system consists of two 300 series stainless steel pipes: an inner pipe through which the cryogenic liquid flows, and an outer pipe that seals a vacuum space and forms a vacuum jacket. Multiple layer insulation (MLI) between the pipes coupled with a low vacuum ensures optimal thermal efficiency. Vacuum Jacketed Pipe efficiently transfers liquids at pressures up to 150 psi or greater. These systems minimize heat leaks to maximize efficiency and savings over time. When an off-the-shelf, one-size-fits-all approach won't do, you can trust Acmes Vacuum Jacketed Pipe systems to meet your unique performance requirements.The Acme Cryogenics team designs manufactures and tests our vacuum jacketed piping and components using the highest available standards. All Inner Process and Outer Jacket Welds are Helium mass spectrometers tested at 1 x 10-9 cc/second, sealed at 9 microns or less.Features - Related BenefitsDOUBLE WALLED CONSTRUCTIONLOWEST HEAT INLEAK ON THE MARKETFACTORY SEALED VACUUM SECTIONSVACUUM INTEGRITY FOR UP TO 20 YEARSPREFABRICATIONEASY SHIPPING AND INSTALLATIONVACUUM INSULATIONMAXIMUM LIQUID PRESERVATIONMINIMAL CRYOGENIC LIQUID LOSSLOWER ULTIMATE GAS COSTSSERIES 304 STAINLESS STEEL FABRICATIONSMAXIMUM SERVICE LIFEBAYONET DESIGN OPTIONSINSTALLATION IS EASYSTANDARD PIPE HANGERSLOW INSTALL AND MAINTENANCE COSTMODULAR CONSTRUCTIONEASY TO EXPAND AND MODIFYINTERNAL LIQUID TRAPSPREVENT BOIL-OFFVACUUM JACKETED VALVESBRANCH AND EQUIPMENT ISOLATIONFLEXIBLE PIPING OPTIONSTHERMAL CONTRACTION AND ARE SIMPLE TO INSTALLAdditional Prep Fees May Apply
