Bendable Vacuum Jacketed Pipe
- 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.
- 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.
- 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.
