Contact SupplierWe provide stainless steel super-insulated Vacuum Jacketed Piping (VJP) systems used for the transfer of liquid nitrogen, oxygen, argon, carbon dioxide, and helium. Each VJP system is custom designed to meet the requirements of the application, while keeping the system economics within budget.
VJP contains an inner line for the transfer of cryogenic liquids with an outer vacuum jacket. The vacuum annular space consists of a multi-layered insulation with an extremely low vacuum level of 9 microns or less. VJP is fifty times more effective than conventional foam-insulated copper in preventing heat leak to the inner line, and VJP is extremely long lasting and meets to ASME B31.3 Code for Process Piping.
