IMPROVED DEVICE FOR SPACING AND CENTERING FOR RIGID PIPELINE WITH DOUBLE WALLS WITH LOW HEAT TRANSFER COEFFICIENT

FIELD: construction, pipeline. ^ SUBSTANCE: invention is related to device for spacing and centering for rigid pipeline with double walls, for instance, of winding type, which is intended for hydrocarbon transport. Device for spacing and centering for rigid pipeline, of pipe-in-pipe type, for instance, like pipeline that may be rolled up, intended for transport of hydrocarbons, at that foresaid rigid pipeline comprises two coaxial pipes separated by annular zone, specified device for spacing and centering is installed in mentioned annular zone to support both coaxial pipes at the distance from each other; differs by the fact that it comprises element from material with low heat conductivity, consisting of aerogel, at that specified element is covered, at least partially, with jacket made of polymer type plastic material. Invention is also related to design of rolled rigid pipeline with double jacket and multiple spacing and centering devices. ^ EFFECT: improvement of pipeline heat insulation. ^ 9 cl, 12 dwg
