Abstract
A method for manufacturing an insulation barrier including providing a body having a cavity therein; introducing a plurality of three-dimensional globules into the cavity, with each globule having a radiation reflector component isolated from the exterior of the globule; and closing the cavity to hold the plurality of globules therein. A method for manufacturing an insulation barrier including loading and breaking down an insulation material in a walled space existing between a first tubular disposed within a second tubular.
Claims11
An apparatus, comprising:
- an outer tubular;
- an inner tubular disposed within the outer tubular such that an annular space is formed between the inner tubular and the outer tubular;
- and
- a plurality of three-dimensional globules disposed within the annular space, wherein each of the globules comprises:
- a central core comprising a radiation reflector material, wherein the radiation reflector material comprises titanium dioxide;
- and
- a layer comprising an insulator material isolating the central core from an exterior of the globule, wherein the insulator material comprises an aerogel compound.
