CryoLinks® Vacuum Insulated Pipe (VIP) is the preferred method for transporting cryogenic liquids and is unmatched in ease of installation, lead times, and cost-effectiveness compared to other mechanical insulated systems. It's fabricated to ASME B31.3. CryoWorks uses stainless steel inner and outer rigid tube/pipe in the manufacturing of our CryoLinks VIP Systems. The piping consists of a factory-fabricated inner line and outer jacket. The inner line carries the cryogenic fluid, while a vacuum space between the inner and outer pipe provides insulation that minimizes heat transfer and boil-off gas (BOG).
