Abstract
A lightweight and compact super-insulation system that is also capable of supporting a high level of compressive load. The system utilizes spacers to provide structural support and utilize controlled buckling of a thin protective outer skin supported by spacers to form strong catenary surfaces to protect insulation material underneath. The spacers may comprise an aerogel, or an aerogel may provide insulation separate from the spacer yet contained within the thin outer skin.
Claims54
A pipe-in-pipe apparatus for thermally insulating a flow line comprising:
- a metallic flow line;
- at least one spacer around the flow line;
- a carrier pipe that is concentrically aligned with the flow line so as to create an annular space between the flow line and carrier pipe, wherein the spacer is in that annular space;
- and
- an aerogel blanket within the annular space between the flow line and the carrier pipe.
