Vacuum Insulated Pipe, FIP and Cryo-Tube

Vacuum Insulated Pipe (VIP) Systems For Liquid Nitrogen Distribution
(Please call or Email for more information, literature, or assistance!)

  • What is the proper system for your application? Static VIP is much more efficient than Dynamic Vacuum or Foam Insulated Pipe. What does your application require?
  • VIP is a coaxial line, a pipe within a pipe. The annular space in between consists of a high vacuum to reduce convective heat, along with Multi-Layer Super Insulation which reflects radiant heat. The internal components are isolated as much as possible to reduce conductive heat.
  • Reduce product (LN2 or Argon) loss costs. Cryogenic Liquid distribution reflects a BTU potential which is reduced from heat infiltration into your cryogenic system. Our systems seek to maintain critical temperatures approaching -200 deg. C at flow rates, which enhance your process.
  • The most efficient way to reduce wasteful pressure buildup and vaporization.
  • Compare utility costs, cool down, and static losses. (see charts)

Vacuum Insulated Valves - and - Cryogenic Non-Insulated Valves

  • VIP Valves are recommended when the elimination of frost, ice, and moisture - as well as maximum system efficiency - are essential. Also, if your process is sensitive to shut down, they add in control of system upgrades and alterations.
  • Cryogenic Valves are used to allow function and safety when cryogenic liquids are in use. They are constructed of either Stainless Steel or Brass and Bronze, the materials capable of functioning safely at the temperatures encountered.

Cryovents - and - Keepcolds

  • CryoVents can remove the vaporized gas that rises to the top of your system. The built-up gas may cause sluggish flow and flow spurts. Cryovents are an effective way to maintain liquid on demand in VIP systems. Requires no electricity.
  • Keepcolds are electronic controls that can be used to vent excess system gas and reduce the time gap in product flow. Any cryogenic system will vaporize gas over time due to the approximately 400-degree temperature difference to the ambient air. A Keepcold will vent gas to allow the system to stay cold enough to provide the quick response needed on some systems.

Flexible VIP

  • Flexible VIP can be used in some applications to correct alignment problems, allow for equipment adjustment when needed, and provide easier disassembly of sections for service or modification.

Bayonet Connections

  • These provide a mechanical connection with a leak-tight shrink-fit seal for sections of VIP to allow for installation and future system changes.

Phase Separators

  • Vent excess gas generated from depressurizing liquid nitrogen at the use points to provide low-pressure, high-quality liquid.

Foam Insulated Pipe (FIP)

  • Lower Initial Cost (but Less Efficient than VIP Systems)
