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.
- Cryogenic Valves and Gas Vents available.
- Straight, elbow, and tee installation kits available for joints welded in the field.
