Vacuum Insulated Pipe

  • What are Vacuum Insulated Pipes?

    Vacuum Insulated Pipes (VIP) are prefabricated insulated pipe sections, where these sections are connected via easy
    to install and extremely low heat leak bayonet joints. VIPs are used for safe and effective transport of liquid nitrogen for MBE process and cold-testing of integrated chips (ICs) in the semiconductor assembly and test facility.

    How it Works

    • Each section is constructed of an inner pipe surrounded by a concentrically-positioned outer pipe.
    • The inner pipe is wrapped with multi layer laminar insulation material with chemical getters granules positioned between the layers.
    • The annular space is completely evacuated to below atmospheric pressure and maintain permanently sealed with very high vacuum.

    Flexible VIPs

    • Super flexible vacuum insulated liquid nitrogen transfer hoses are used in a wide variety of applications including tool connections and custom OEM applications.
    • The coaxial bellowed construction allows for optimal flexibility. The use of lightweight stainless steel reduces cool-down loss to an absolute minimum.
    • C-Flex hoses are protected by a stainless steel spiral wrap or a braided outer cover. Available in various sizes: 1/4" ID, 3/8" ID, and 1/2" ID stocked in standard lengths for immediate availability.

    Rigid VIPs

    • Rigid VIPs are all stainless steel coaxial vacuum insulated piping system.
    • Modular by design, Rigid VIP spools are joined together with close tolerance bayonet connections. Each section is evacuated, sealed and then tested for vacuum integrity.
    • This advanced piping system minimizes heat gain between the inner carrier pipe and the outer jacket.
    • Our rigid VIP product minimizes pressure drop and improves flow characteristics. By incorporating strategically located flexible sections when required, Rigid VIPs are easy to install for both indoor and outdoor installations.
    • Cryogas offer a complete line of components including in-line venting devices, phase separators and gas traps to maximize the system performance.
