Multi-layered conduit

A protective structure comprising

• a master pipe, a plurality of coaxial prism structures, a plurality of spoke structures, and a plurality of insulating spaces;
• wherein the plurality of spoke structures interconnect each of the plurality of coaxial prism structures;
• wherein the plurality of spoke structures further forms the plurality of insulating spaces;
• wherein the master pipe inserts through the plurality of coaxial prism structures such that the combination of the master pipe structure and the plurality of coaxial prism structures form a coaxially oriented composite prism structure;
• wherein the protective structure is an insulating structure;
• wherein the master pipe transports a fluid through the protective structure;
• wherein each of the plurality of spoke structures is a disk-shaped structure;
• wherein each of the plurality of spoke structures is an extension structure that sets the reach between the exterior surface of the lateral face of an initial coaxial prism structure selected from the plurality of coaxial prism structures to the interior surface of the lateral face of a subsequent coaxial prism structure selected from the plurality of coaxial prism structures;
• wherein the plurality of spoke structures form spacers that fix the relative positions of the plurality of coaxial prism structures such that the plurality of coaxial prism structures combine to form a composite prism structure;
• wherein the lateral face of the disk structure of each spoke structure selected from the plurality of spoke structures attaches to the lateral faces of the prism structures of the initially selected coaxial prism structure and the subsequently selected coaxial prism structure such that the congruent ends of the disk structure of the selected spoke structure projects radially away from the aligned center axes of the initially selected coaxial prism structure and the subsequently selected coaxial prism structure.
