Vacuum Insulated Piping
Elevate your cryogenic fluid handling with HL Cryogenics’ Vacuum Insulated Hoses (VIHs), also known as vacuum jacketed hoses, the premier choice for minimizing heat gain or loss and maximizing system efficiency. Offering dramatically reduced heat leakage – just 0.035 to 0.05 times that of conventional insulation – our Vacuum Insulated Hoses (VIHs) deliver unparalleled energy and cost savings compared to traditional piping insulation methods. They are easy to use and maintain for any top of the line cryogenic equipment.
Engineered for demanding cryogenic environments, our Vacuum Insulated Hoses (VIHs), or vacuum jacketed hoses, undergo rigorous testing and quality control to ensure reliable and leak-free performance. HL Cryogenics’ Vacuum Insulated Hoses (VIHs) are compatible with a comprehensive range of cryogenic fluids, including:
- Liquid Oxygen (LOX): For medical, industrial, and aerospace applications.
- Liquid Nitrogen (LN2): For cryopreservation, cooling, and inerting.
- Liquid Argon (LAr): For welding, plasma cutting, and research.
- Liquid Hydrogen (LH2): For fuel cells, energy storage, and advanced propulsion.
- Liquid Helium (LHe): For superconducting magnets, research, and medical imaging.
- Liquefied Ethylene Gas (LEG): For chemical processing and polymer production.
- Liquefied Natural Gas (LNG): For power generation and transportation.
Key Features and Benefits:
- Ultra-Low Heat Leakage: Significantly minimizes boil-off and maximizes fluid utilization, conserving valuable resources.
- Substantial Cost Savings: Reduces energy consumption, minimizes product loss, and lowers overall operational expenses.
- Durable Construction: Robust stainless steel construction and high-quality vacuum insulation ensure long-term reliability and minimize maintenance.
- Flexible and Customizable Design: Available in a variety of lengths, diameters, and end connections to easily adapt to diverse system configurations and application requirements.
- Wide Application Versatility: Ideal for use in air separation plants, industrial gas facilities, aviation and aerospace, electronics manufacturing, pharmaceutical production, food and beverage processing, scientific research laboratories, and more.

Four Connection Types
In order to maximize the different needs of customers, there are usually four connection types for Vacuum Insulated Flexible Hose (VIH). The first three connection types apply only to the connection positions between Vacuum Insulated Flexible Hoses (VIHs). The fourth one, threaded connection type is generally used only for Vacuum Insulated Flexible Hose (VIH) connections to equipment and storage tank.
When Vacuum Insulated Flexible Hose (VIH) connects with equipment, storage tank and so on, the connection joint can be customized according to customer requirements.

Dynamic and Static Vacuum Insulated Flexible Hose
Vacuum Insulated (VI) Flexible Hose can be divided into Dynamic and Static VI Flexible Hose.
l The Static VI Hose is fully completed in the manufacturing factory.
l The Dynamic VI System is offered a more stable vacuum state by a continuous pumping of vacuum pump system on site, and vacuuming treatment will no longer take place in the factory. The rest of the assembly and process treatment is still in the manufacturing factory. So, the Dynamic VJ Piping needs to be equipped with a Vacuum Pump System.
Dynamic Vacuum Insulated Flexible Hose | Static Vacuum Insulated Flexible Hose | |
Introduction | The vacuum degree of the vacuum interlayer is monitored continuously, and the vacuum pump is automatically controlled to open and close, to ensure the stability and effectiveness of vacuum degree | VJ Flexible Hoses complete the vacuum insulation work in the manufacturing plant. |
Advantages | The vacuum retention is more stable, basically eliminate the vacuum maintenance in the future working. | More economical investment and simple on-site installation |
