Vacuum Insulated Pipe
Vacuum Insulated Pipe (VIP), also known as Vacuum Jacketed Pipe (VJP), is a critical component for minimizing heat gain or loss during the transfer of cryogenic fluids and other temperature-sensitive substances. Its superior thermal performance reduces operating costs and enhances process efficiency. Designed for seamless integration with existing cryogenic equipment and compatibility with Vacuum Insulated Hoses (VIHs), the Vacuum Insulated Pipe (VIP) ensures optimal performance and reliability across diverse applications. These also increase the efficacy of the cryogenic equipment by reducing waste!
Key Applications:
- Cryogenic Liquid Transfer: Vacuum Insulated Pipe (VIP), or Vacuum Jacketed Pipe (VJP), efficiently transfers liquid nitrogen, liquid oxygen, liquid argon, and other cryogenic fluids while minimizing boil-off. This helps to reduce energy costs. These liquids can be transferred with the help of Vacuum Insulated Hoses (VIHs).
- LNG/CNG Transfer and Distribution: Critical for the safe and efficient transfer of liquefied natural gas (LNG) and compressed natural gas (CNG) during transportation and distribution. Modern Vacuum Insulated Pipe (VIP) keeps up with today’s stringent demands.
- Pharmaceutical Manufacturing: Maintaining precise temperature control is essential in pharmaceutical production. Vacuum Insulated Pipe (VIP), or Vacuum Jacketed Pipe (VJP) ensures the stable transfer of temperature-sensitive materials. The temperature properties can be augmented with Vacuum Insulated Hoses (VIHs).
- Food Processing and Storage: The system can be properly kept at freezing temperatures with the help of HL Cryo’s systems. Precise temperature control helps to maintain peak performance. These are always connected to a Vacuum Insulated Pipe (VIP).
- Aerospace and Research: Vacuum Insulated Pipe (VIP) supports cutting-edge research and development in aerospace, particle physics, and other fields where extreme temperatures are involved, which can be improved with Vacuum Insulated Hoses (VIHs). These have to function at the highest levels with performance Vacuum Insulated Pipe (VIP).
The Vacuum Insulated Pipe (VIP), also referred to as Vacuum Jacketed Pipe (VJP), from HL Cryogenics is the best in thermal performance and reliability for cryogenic fluid transfer. It’s perfect for a wide range of applications.
Three Connection Types of VI Piping
The connection types outlined here pertain specifically to the interfaces between Vacuum Insulated Pipes. When connecting Vacuum Insulated Pipe to equipment, storage tanks, or other systems, the connection joint can be customized to meet specific customer requirements.
To accommodate a diverse range of customer needs, Vacuum Insulated Pipe (VIP) systems offer three primary connection types:
- Vacuum Bayonet Connection with Clamps: Designed for quick and easy assembly.
- Vacuum Bayonet Connection with Flanges and Bolts: Provides a more robust and secure connection.
- Welded Connection: Offers the highest level of structural integrity and leak tightness.
Each type provides unique advantages and is suited for different operating conditions:

Dynamic and Static Vacuum Insulated Piping System
Vacuum Insulated (VIP) Piping System can be divided into Dynamic and Static Vacuum Insulated 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 |
