Vacuum insulated piping

Nexans cryogenic systems are in-house engineered and built on core technology of flexible joint-free vacuum-insulated cryogenic transfer lines. Vacuum insulated transfer lines, also called vacuum jacketed piping, are double-walled piping systems designed to achieve superior thermal insulation between the inner and outer pipe. In comparison to rigid systems, Nexans joint-free solutions avoid the complexity of managing, welding and cleaning rigid pipes.

Nexans has developed 2 full ranges of flexible vacuum insulated transfer lines that can be applied for static and dynamic applications. Nexans CRYOFLEX ® is the product range for static applications while Nexans HIGHFLEX is the product range for dynamic applications, used for applications requiring a high flexibility. These systems and their thermal insulation are originally designed for transfering liquefied helium at temperature as low as 4K, and maximum pressure up to 20 bar for Nexans CRYOFLEX ® and 40 bar for Nexans HIGHFLEX.
