Product Application

The Special Connector is meticulously engineered to provide a secure, leak-tight, and thermally efficient connection between cryogenic storage tanks, cold boxes (found in air separation and liquefaction plants), and associated piping systems. It minimizes heat leak and ensures the integrity of the cryogenic transfer process. The robust design is compatible with both Vacuum Insulated Pipes (VIPs) and Vacuum Insulated Hoses (VIHs), making it an indispensable component in any cryogenic infrastructure.

Key Applications:

  • Connecting Storage Tanks to Piping Systems: Facilitates the secure and reliable connection of cryogenic storage tanks to Vacuum Insulated Pipe  (VIP) systems. This ensures a seamless and thermally efficient transfer of cryogenic fluids while minimizing heat gain and preventing product loss due to vaporization. This also keeps Vacuum Insulated Hoses secure from breaking.
  • Integrating Cold Boxes with Cryogenic Equipment: Enables the precise and thermally isolated integration of cold boxes (core components of air separation and liquefaction plants) with other cryogenic equipment, such as heat exchangers, pumps, and process vessels. A well run system ensures the safety of Vacuum Insulated Hoses (VIHs) and Vacuum Insulated Pipes (VIPs).
  • Ensures safety and ease of access for any cryogenic equipment.

HL Cryogenics' Special Connectors are engineered for durability, thermal efficiency, and long-term reliability, contributing to the overall performance and safety of your cryogenic operations.

Special Connector for Cold-box and Storage Tank

The Special Connector for Cold-box and Storage Tank offers a significantly improved alternative to traditional on-site insulation methods when connecting Vacuum Jacketed (VJ) Piping to equipment, ensuring optimal performance and ease of installation. In particular, this system is useful when working with Vacuum Insulated Pipes (VIPs) and Vacuum Insulated Hoses (VIHs), for smooth operation. On site insulation often leads to issues.

Key Benefits:

  • Superior Thermal Performance: Dramatically reduces cold loss at connection points, preventing icing and frost formation, and maintaining the integrity of your cryogenic fluids. This leads to less issues for the use of your cryogenic equipment.
  • Enhanced System Reliability: Prevents corrosion, minimizes liquid gasification, and ensures long-term system stability.
  • Streamlined Installation: Offers a simplified, aesthetically pleasing solution that significantly reduces installation time and complexity compared to traditional on-site insulation techniques.

Industry Proven Solution:

The Special Connector for Cold-box and Storage Tank has been successfully applied in numerous cryogenic projects for over 15 years.
