A double-walled pipe consisting of coaxial pipes of different diameter is assembled from two halves (3) which complement one another to form a double-walled pipe, each of which consists of two half pipes (4, 5) whose base planes (8, 9) run virtually at right angles to one another. These two half pipes (4, 5) of a single half (5) are connected to one another via a flange (6), which projects radially outwards in the base plane of the half pipe (5), is placed on one edge of the half pipe (5) with the smaller half-diameter and whose width corresponds to the difference between the half-diameters of the two half pipes (4, 5). Such a double-walled pipe can be used particularly advantageously as a connection piece for the connection of coaxial double-walled pipe sections, in this case each of the two halves (3) of this connection piece consisting of a half pipe (4) having an external diameter corresponding to the internal diameter of the outer pipes (1) of the two pipe sections to be connected, and of a half pipe (5) having an internal diameter corresponding to the external diameter of the inner pipes (2) of these pipe sections. <IMAGE> |
