Techniguard™ Bendable Vacuum Jacketed Pipe

Bendable Pipe noborder
  • Lengths up to 60 feet (19 meter).
  • Choice of external covering to best fit your application needs.
  • Choice of end connections.
  • Valves, gas traps, gas vents, and thermocouple vacuum gauge tubes can be added.
  • ASME B31.3, CRN (Canadian Registration Number) and liquid oxygen certification available.

Benefits

  • Provides a more cost effective installation than rigid pipe with only a small loss in performance.
  • Utilizes a bendable design that minimizes heat leakage when VJP is bent.
  • Low maintenance Vacuum Jacketed Pipe (VJP) doesn’t require external vacuum pumps or pump maintenance.
  • Close-tolerance bayonets eliminate the need for field welding or soldering and allow easy system reconfiguration.
  • Can be coiled for less expensive packaging and shipping.

Easy to Install

  • Simplifies cryogenic system layout, reducing the need for precise system measurements.
  • Lower install cost than foam covered pipe or pipe with foam joints.
  • Easy connections with our standardized bayonets to other R-Series and B-Series VJP.
  • No cryogenic piping experience is required for installation.

Construction

  • Stainless steel inner and outer construction for maximum strength and corrosion resistance.
  • Vacuum and multi-layer super insulation creates a low heat transfer rate which minimizes cryogenic liquid boil-off.
  • Embedded getter materials absorb outgassed molecules in the vacuum space. Pipe is heated during evacuation to remove molecules that can outgas later.
  • Bayonet connections provide an easy connection between cryogenic lines.
  • Liquid nitrogen, CO2, argon, and hydrogen ready; Liquid oxygen option is available.
