Liquid Hydrogen Vacuum Insulated Pipe

Product Overview

The liquid hydrogen vacuum insulated pipe is a high-performance vacuum-insulated pipeline designed for the transfer of ultra-low temperature liquid hydrogen. It is widely used in industries such as hydrogen energy, air separation, energy equipment, aerospace, electronics and superconducting devices, scientific research, advanced materials, and chemical processing.

Specifically engineered for the extremely low temperature of liquid hydrogen (around 20 K) and the characteristics of hydrogen media, this pipeline enables stable and efficient cryogenic transfer in liquid hydrogen storage, transfer, and distribution systems. It provides a safe and efficient alternative to traditional insulated pipelines in liquid hydrogen applications.

Working Principle

The liquid hydrogen vacuum insulated pipe utilizes high-vacuum multilayer and multi-shield insulation technology. Multiple layers of high-efficiency insulation composite materials are installed between the inner and outer stainless steel pipes, while maintaining a stable high-vacuum environment.

By combining multilayer radiation shields with vacuum insulation, the structure effectively suppresses heat transfer caused by conduction, convection, and radiation. This significantly reduces heat leakage into the pipeline system.

Compared with conventional insulated pipelines, this design offers much lower heat leakage, effectively reducing hydrogen boil-off and improving the overall efficiency and safety of cryogenic transfer systems.
