Earth-laid fluid conveying pipeline, particularly drinking water- or waste water pipeline, has heat exchange unit which has multiple spiral windings, where heat exchange unit is arranged outside wall of fluid conveying pipeline
The earth-laid fluid conveying pipeline (13) has a heat exchange unit (20) which has multiple spiral windings. The heat exchange unit is arranged outside the wall of the fluid conveying pipeline. The spiral windings run around the wall of the fluid conveying pipeline. The spiral windings are made of plastically deformable material. The heat exchange unit in the area of spiral windings is formed from a multi-layer compound pipe or from a copper pipe with a protective jacket. An independent claim is also included for a method for subsequent mounting of a fluid conveying pipeline with a heat exchange unit.
