Abstract

Two pipes (1, 1') for media run, embedded all round in expanded-foam insulation (2), in an outer jacket pipe (3). The ends (4) of said pipes project from this insulation and are intended to be connected to the projecting ends of the corresponding pipes for media of an identically constructed pipeline section, at the point where the pipeline section is laid. The pipes (1, 1') for media are constructed as helical pipes over at least a part of their length in the insulation (2). In contrast, the ends (4) of the pipes (1, 1') for media projecting from the insulation are straight and run parallel to the axis of the pipeline section. As a result of the connection with the outer jacket pipe (3), which is fixed in the ground, via the insulation material (2), the pipes (1, 1') for media are virtually immovable in the longitudinal direction of the pipeline section. On the other hand, because of their helical course, a certain amount of expansion in the case of heating, and contraction in the case of cooling, of the helix in the insulation layer is possible in order to compensate for thermal expansions within the pipeline section.
