Liquid Hydrogen Vacuum Insulated Hose

Product Overview

The liquid hydrogen vacuum insulated hose is a high-performance flexible pipeline designed for the transfer of liquid hydrogen and other ultra-low temperature media. It is widely used in cryogenic systems across hydrogen energy, aerospace, energy equipment, scientific research, cryogenic engineering, and advanced materials industries.

Specifically engineered for the liquid hydrogen temperature range (around 20 K) and the unique characteristics of hydrogen, the hose adopts a high-vacuum multilayer insulation structure. This design achieves extremely low heat leakage, significantly outperforming conventional insulated hoses and pipelines. As a result, it effectively reduces hydrogen boil-off while improving system efficiency and operational safety.

Working Principle

The hose features a double-layer stainless steel structure. Between the inner and outer tubes, multiple layers of high-efficiency insulation materials are installed and maintained under a stable high-vacuum environment.

By combining multilayer radiation shielding with vacuum insulation, the design effectively minimizes heat transfer caused by radiation, conduction, and convection. This structure ensures extremely low heat leakage during operation.

The vacuum-jacketed structure also prevents condensation and frost formation on the outer surface when transporting liquid hydrogen, reducing cold energy loss and external heat ingress while ensuring safe and stable long-term transfer of liquid hydrogen.
