Abstract: This invention discloses an insulated, longitudinally segmented, rigid conduit containing several pipes of varying sizes. The conduit comprises any number of separate pipe carrying segments wherein the rigid casing, the rigid insulation, and the pipe constitute integral parts of these segments providing rigidity to them. The invention discloses multiple unit conduits and a single unit suitable for use as a conduit by itself, which can be attached to similar units or to other surfaces such as floors, walls or ceilings. The conduit is designed to withstand external bending and shear stresses and internal fluid pressures.
