Insulated pipeline for transporting cryogenic liquid, has middle pipe of sufficient length such that during assembly, in cooperation with the linking parts, it prevents formation of a thermal bridge between the inner and outer pipes

摘要

Inner, middle, and outer pipes are linked using linking parts (5,6) to join the sections (2a,2b,3a,3b,4a,4b) of each pipe and to take up the loads produced by thermal contraction when the pipes change temperature. The middle pipe (3) is of sufficient length such that during assembly, in cooperation with the linking parts, it prevents formation of a thermal bridge between the inner and outer pipes (2,4).
