    Vacuum Jacketed Pipe, also known as Vacuum Insulated Pipe or Cryogenic Piping, is a highly effective solution designed for the safe and efficient transfer of low boiling point liquids—such as liquid nitrogen or liquid oxygen—from one location (point “A”) to another (point “B”). This type of piping is especially critical in industries where maintaining extremely low temperatures during liquid transfer is essential.

    In a typical vacuum insulated pipe segment, as illustrated in the diagram below, the inner pipe or tube contains the process medium. This inner pipe is surrounded by multiple layers of mylar-based super-insulation, which serve to minimize heat ingress and thereby keep the contained fluid at a consistently low temperature.

    To further prevent thermal transfer, low-heat leak spacers are strategically placed between the inner and outer tubes. These spacers keep the two tubes separated and ensure that there is no direct metal-to-metal contact, which could otherwise create a path for heat to leak into the inner tube.

    The outer pipe, which encapsulates the inner tube and its insulation, is integral to the system. A pumpout port is fitted to this outer pipe, which allows for the removal of air from the annular space between the inner and outer pipes. By evacuating this space, a high vacuum is created. This vacuum serves as an insulating barrier that dramatically reduces heat transfer, thereby ensuring that the liquid within remains at its cryogenic temperature as it is transported through the pipe.

    These vacuum insulated pipes are essential components in various applications including the distribution of liquid gases in laboratories, healthcare facilities, and industrial plants. They are engineered to provide maximum thermal performance and are designed for easy installation and long-term, reliable operation.

    By using vacuum jacketed pipe from AET, you are choosing a product designed with precision and constructed to the highest standards, ensuring that your cryogenic liquids are transferred efficiently and safely.
