ABSTRACT:
For use in heat-insulated pipe-lines produced from at least two heat-insulated pipe units joined end to end, each heat-insulated pipe unit consisting of a pipe surrounded over the greater part of its length by at least one layer of heat-insulating foam material which is in turn enclosed by an outer jacket of fluid-impervious protective material, the end parts of the pipe projecting beyond the corresponding ends of the layer or layers of heat-insulating material and the end parts of the jacket projecting likewise but for a shorter distance, so that annular recesses are formed in the ends of the pipe unit. The pipes of these two pipe units are interconnected end to end by a butt weld or mechanical jointing element between the projecting end parts thereof. Annular seals of rubber-like material are located in the annular recesses in the proximate ends of the two pipe units. A tubular cover extends across the gap between the proximate end parts of the jackets of the two pipe units in spaced coaxial relationship with the interconnected pipe end parts. The annular space or spaces enclosed by the seals and the cover and surrounding the interconnected pipe end parts are filled with heat-insulating foam material.
