Abstract
An insulation system insulating a carrier conduit carrying a hot gas or liquid, buried in permafrost, allows expansion and contraction of said carrier conduit, and directionally disperses heat from the conduit minimizing thawing of permafrost. A carrier conduit carries a gas or liquid. A carrier insulation encases the carrier conduit. An outer conduit encases the carrier insulation. The outer conduit top portion includes two symmetrical flanges integrally formed on two sides of said outer conduit. An outer insulation partially encases the outer conduit. There is no outer insulation on the upper part of outer conduit; and thus, outer conduit top portion remains selectively uncovered. Any heat escaping through the carrier insulation, travels in a circumferential direction along the outer conduit and not in a radial direction because of outer insulation. The heat escapes in the soil above the insulated conduit, protecting the permafrost.
