Vacuum Insulated Piping

Vacuum Insulated Pipe (VI Piping), namely Vacuum Jacketed Pipe (VJ Piping), 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 Jacketed Pipe, Vacuum Jacketed Hose, Vacuum Jacketed 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 tanks, dewars and coldboxes etc.) in industries of air separation, gases, aviation, electronics, superconductor, chips, automation assembly, food & beverage, pharmacy, hospital, biobank, rubber, new material manufacturing chemical engineering, iron & steel, and scientific research etc.

Three Connection Types of VI Piping

The three connection types here apply only to the connection positions between VI pipes. When VI Pipe connects with equipment, storage tank and so on, the connection joint can be customized according to customer requirements.

In order to maximize the different needs of customers, Vacuum Insulated Pipe has developed three connection types, namely Vacuum Bayonet Connection Type with Clamps, Vacuum Bayonet Connection Type with Flanges and Bolts and Welded Connection Type. They have different advantages and are suitable for different working conditions.

Dynamic and Static Vacuum Insulated Piping System

Vacuum Insulated (VI) Piping System can be divided into Dynamic and Static VI Piping System.

l The Static VI Piping is fully completed in the manufacturing factory.

l The Dynamic VI Piping is offered a more stable vacuum state by a continuous pumping of vacuum pump system on site, and the rest of the assembly and process treatment is still in the manufacturing factory.

  Dynamic Vacuum Insulated Piping System Static Vacuum Insulated Piping System
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 VJPs 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
