Vacuum Insulated Piping
Vacuum Insulated Hose (vacuum hose), namely Vacuum Jacketed Hose, as a Perfect substitute for conventional piping insulation. Compared with conventional piping insulation, the heat leakage value of VIP is only 0.05~0.035 times of conventional piping insulation. Significantly save energy and cost for customers.
The product series of Vacuum Insulated Hose, Vacuum Insulated Pipe, Vacuum Insulated Valve, and Phase Separator in HL Cryogenic Equipment Company, which passed through a series of extremely strict technical treatments, are used for transferring of liquid oxygen, liquid nitrogen, liquid argon, liquid hydrogen, liquid helium, LEG and LNG, and these products are serviced for cryogenic equipment (e.g. cryogenic tank, dewar and coldbox etc.) in industries of air separation, gases, aviation, electronics, superconductor, chips, pharmacy, hospital, biobank, food & beverage, automation assembly, rubber, new material manufacturing chemical engineering, iron & steel, and scientific research etc.
Four Connection Types
In order to maximize the different needs of customers, there are usually four connection types for VI Flexible Hose. The first three connection types apply only to the connection positions between VI Flexible Hoses. The fourth one, threaded connection type is generally used only for VI Hose connections to equipment and storage tank.
When VI Flexible Hose 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 |
