摘要
Piping, in particular conveying piping, support piping or anchor piping for a geothermal probe for the generation of geothermal energy, in particular deep geothermal energy, with thermal energy being transported by means of a preferably liquid heat transfer medium from a deep area to an upper area of the geothermal probe, (A) with an outer tube (13) made of a metal and (b) with an inner tube (15) provided within the outer tube (13) made of a thermally insulating material, in particular a plastic, which consists of a plurality of inner tube sections (15a), (c) wherein the inner pipe (15) at two or more axial positions of the tubing (5) by means of a load transfer device (23) for introducing axial forces acting on the inner pipe (15) onto the outer pipe (13) with the outer tube (13) is connected, characterized in that (d) that in axial sections between two load transfer devices (23) the inner pipe sections (15a) at coupling points between two immediately adjacent ends of the inner pipe sections (15a) and / or at least at a coupling point between one of the two load transfer devices (23) and the immediately adjacent one The end of the respective inner pipe section (15a) are coupled, the coupling being generated or at least supported by axial pressure forces at the coupling points without a material bond.
