Liquid Helium Vacuum Insulated Pipe

Product Overview

The Liquid Helium Vacuum Insulated Pipe is a high-performance cryogenic pipeline designed for the transfer of liquid helium. It is widely used in air separation, gas processing, aerospace engineering, electronic equipment, superconducting systems, semiconductor manufacturing, automated assembly, food and beverage processing, pharmaceuticals, medical facilities, biobanks, advanced materials, and chemical industries.

This pipeline is commonly applied for cryogenic media transfer between low-temperature equipment and systems, such as cryogenic storage tanks, Dewar vessels, and cold boxes. As an upgraded alternative to conventional insulated pipelines, it significantly reduces evaporation losses of cryogenic media during transfer, improving system efficiency and operational reliability.

Working Principle

The liquid helium vacuum insulated pipe adopts a high-vacuum multi-layer multi-shield insulation structure. Multiple layers of insulation composite materials are placed between double-layer stainless steel pipes, while maintaining a high-vacuum environment.

This design effectively suppresses heat conduction, convection, and radiation, greatly minimizing external heat ingress into the pipeline. As a result, the heat leakage is only about 0.035–0.05 times that of traditional insulated pipelines, significantly improving cryogenic insulation efficiency and reducing energy consumption.
