Patent ID: 8162034

Claim:
An elongated structure for the transmission of fluid-based compositions at non-ambient temperatures comprising: a conduit for the transmission of a fluid-based composition; at least two flexible elongated temperature control conduits for the transmission of a temperature control fluid, each of said temperature control conduits having a pair of generally opposing walls, wherein a first wall is positioned radially outward relative to said transmission conduit, a second wall is positioned radially inward relative to said transmission conduit, a relatively rigid elongated reinforcement member positioned in one of the first and second walls and projecting inwardly into the temperature control conduit, and a tab projecting outward from the wall in which the reinforcement member is positioned, wherein said at least two flexible elongated temperature control are composed of a flexible polymeric material; and an elongated cover holding said elongated temperature control conduits in thermal communication with said transmission conduit, wherein the cover has an outwardly oriented surface and an opposed inwardly oriented surface disposed radially inward thereof, and at least two elongated pockets defined on the inwardly oriented surface of the elongated cover, each pockets containing the projecting tabs of the associated flexible elongated temperature control conduit, the pockets positioned on the inward surface such that the flexible elongated temperature control conduits are positioned in spaced relationship to one another, the outwardly oriented surface of the cover in radial spaced relationship to the first conduit and defining a cavity spaced between the cover and the first conduit, wherein the flexible elongated conduits are positioned in said cavity, wherein said flexible elongated temperature control conduits are positioned between the transmission conduit and the elongated cover.
