Construction

Nexans HIGHFLEX is a pipe-in-pipe construction made of two corrugated stainless steel tubes. The parallel corrugation provides high flexibility for increased bendability. Design includes single-braided stainless steel armoring on all tubes for enhanced pressure stability & resistance to mechanical fatigue.

High performance thermal insulation is achieved between process and outer tubes from combined action on heat radiation, conduction and convection

• Multilayer insulation material: multiple layers of highly reflective film separated with spacer fleece is lapped on process tube to reflect heat radiation outside of the construction
• High vacuum is generated in the annular space and stabilized with molecular sieves and chemical getter to prevent heat convection.
• Low loss spacer minimize contact area and subsequent heat conduction between outer and process tubes

All Nexans HIGHFLEX lines integrate a pumping module equiped with burst disks, a pumping port and a vaccum-sensing port

Nexans HIGHFLEX is available over a diameter range for the process tube from DN8 to DN150. Please consult us directly for product details on configurations larger than DN50.
