Vacuum tube by the inner tube, outer tube and multi-layer insulation materials, laminated multi-layer insulation material made of composite to reduce radiation heat transfer; and sandwich pumping into a high vacuum state to reduce convection heat transfer; Low thermal conductivity material isolation, in order to reduce the heat transfer of the solid, so as to control the cold loss of the inner tube to a minimum, fully meet the low temperature liquids (LOX, LN2, LCO2, LAr, LH2, LHe, LNG) and other long-distance transport, Vacuum Multilayer Adiabatic Cryogenic Liquid Conveying.
Characteristics of the vacuum tube
The inner tube at liquid nitrogen temperature, the contraction rate of 0.3%, for the hard tube, in the inner tube or outer tube must also be set on the compensator, in the pipeline directly installed high vacuum multilayer insulated low-temperature globe valve, check valve, emergency Shut-off valves and safety systems. Plug-in vacuum connector junction leakage heat is small, no frost, condensation, special needs of customers with special structural forms of vacuum insulation pipe system.
Vacuum tube making material
All made of (SUS304) stainless steel, and the use of the current special advanced multi-layer insulation materials and gas adsorbents, low thermal conductivity of the support.
Vacuum tube installation
It is easy to install and maintain, and it can be installed by professionals. It can shorten the installation time, save the works and reduce the costs.
