Liquid Helium Vacuum Insulated Hose

Product Overview

The Liquid Helium Vacuum Insulated Hose is a high-performance cryogenic transfer hose designed for liquid helium and other ultra-low temperature media. It is widely used in air separation, superconducting technology, aerospace, electronics manufacturing, scientific research, biological storage, food refrigeration, pharmaceuticals, and advanced materials industries.

The hose adopts a high-vacuum multi-layer shield insulation structure, which effectively reduces heat transfer. Compared with conventional insulated pipelines, it offers significantly lower heat leakage, thereby reducing evaporation loss of cryogenic liquids and improving the efficiency of cryogenic fluid transfer.

Working Principle

The liquid helium vacuum insulated hose features a double-layer stainless steel structure, with multiple layers of insulation composite materials filled between the inner and outer pipes while maintaining a high-vacuum environment. Through multi-layer shielding and vacuum insulation technology, heat conduction and thermal radiation are effectively minimized.

This structure ensures that heat leakage is only a small fraction of that in conventional insulated pipelines, providing excellent cryogenic insulation performance. The vacuum jacket structure also prevents condensation or frost formation on the outer surface during the transfer of ultra-low temperature media such as liquid helium, reducing cold energy loss and ensuring stable system operation.
