Abstract

A flexible pipeline to transport a frozen medium is provided where the pipeline has a central guide tube (1) of metal, undulated transversely of its longitudinal direction for conducting the frozen medium, and transversely of its longitudinal direction a limiting type tube (6) of metal. In the intermediate space (7) between the guide tube (1) and the limiting type pipe (6), is a cooling space for conducting an outer frozen medium, and wherein the intermediate space (7) is evacuated. That over the entire length of the pipeline around the guide tube (1) is wound at least one undulated cooling pipe (4) of metal which has a significantly smaller outer diameter than the guide tube (1) and forms a cooling space for conducting the outer frozen medium therethrough. That circumferentially over the entire length around the unit of the guide tube (1) and the cooling tube (4), a layer (5) is applied which serves as a super insulation and has at least one layer of reflecting foil.
