Abstract

A pipeline to transport a frozen medium is indicated which has an outer transversely to its longitudinal direction undulated limiting pipe, arranged inside are at least one metal pipe for guiding the frozen medium as well as a cooling pipe composed of metal for guiding a second frozen medium. In the limiting pipe hollow areas are available for evacuation. Fitted inside the limiting pipe are at least two transversely to their longitudinal direction undulated metal pipes for guiding the frozen medium, which are each surrounded by a thermal insulation. During the operation of the pipeline the frozen medium is led in different directions through both the metal pipes. Attached around both the metal pipes and the cooling pipe is a pipe shaped closed sleeve composed of a thermally good conductive material that is in contact with the cooling pipe.
