Techniguard L-Series Pipe

Benefits

  • L‐Series vacuum jacketed pipe reduces heat losses by more than a factor of 10 compared to foam covered pipe.

  • Does not degrade like foam insulated pipe and maintains insulative properties.

  • Higher pressure rating for liquid CO2 and other cryogens.

  • Low maintenance Vacuum Jacketed Pipe (VJP) doesn’t require external vacuum pumps or pump maintenance.

  • Economically priced.

  • Valves and vents are also available.

Construction & Installation

  • 300 Series Stainless steel inner and outer construction for maximum strength and corrosion resistance.

  • Liquid Nitrogen, CO2, Argon and LNG ready.

  • Pipe is heated during evacuation to enhance vacuum acquisition.

  • Embedded getter materials absorb outgassed molecules in the vacuum space for longer life.

  • Helium mass spectrometer leak tested to ensure vacuum integrity.

  • Pre‐built modules allow rapid configuration into a system when you need it.

  • Installation kits make adding joint insulation easier and eliminate the need to evacuate after welding joints in the field.

Variety of Options

  • Straight lengths available from stock in 2 – 20 foot lengths at 1′ increments.
  • 1”, 2”, and 3” diameter inner pipe sizes.
