ABSTRACT:
An insulated conduit composed of an inner structural tubing with each length or bend of said tubing having a bell socket at one end with a matching spigot joint at the other end, and so arranged that one is enabled to assemble comparitively long continuous lengths of the insulated conduit. Resting blocks are placed at appropriate position and distances within the inner structural tubing whereby energy carrying piping may be inserted within the inner structural tubing and rest upon said blocks. The energy carrying piping is protected from loss of heat energy by the insulative value of the ambient air within the inner structural tubing and also by the inclusion of inert air spaces located between a series of structural ribs which form a support between the inner structural tubing and an outer insulation jacket.
The outer insulation jacket having annular tongue and groove matching configurations at the ends combined with a system of wire anchors which are incorporated for making easily formed joints being moisture resistant and thus protecting the inner energy carrying piping from corrosion and heat loss. The use of a binding material such as wire is employed to hold continuous lengths of the insulated conduit together during installation.
