Flexible Vacuum Insulated Pipe
CRANE® Cryogenics Flexible Vacuum Insulated Pipe (FVIP) is a vacuum insulated, stainless steel flexible pipe. Each spool section is factory evacuated and sealed, eliminating the need for any on-site vacuum pumps. Flexible VIP is modular in construction and available in standard line sizes of ¾”, 1¼” & 2″ ID.
Key Features And Benefits
- Modular design, highly reusable, facilitates future expansions.
- Flexibility simplifies installations (above drop tile ceilings and below raised test floors).
- Shipping is less expensive as the assemblies are coiled in small wooden crates.
- Need something quick? We stock reels of raw flex hose material.
