Abstract
A thermally-insulated pipeline for the transportation of a cryogenic liquid, comprising three coaxial pipes formed of sections, one inner pipe made of a material having a low thermal expansion coefficient, a middle pipe and an outer pipe made of steel. The pipes are linked by linking parts which join sections of each respective pipe and take up the loads produced by thermal expansion or contraction when the pipes change temperature. The linking parts that join the inner pipe and the middle pipe are separated from the linking parts that join the middle and outer pipe, so that a thermal bridge cannot form between the inner pipe and the outer pipe.
