LINE ELEMENT WITH AIR GAP INSULATION

The invention relates to a line element with air gap insulation, in particular to a line element (10) for an exhaust gas line, for which an inner line (IS) is surrounded by an outer line (AS) formingan intermediate space (15). In a preferred embodiment, the inner pipe (IS) is produced from a strip (...

Beschreibung
Zusammenfassung:	The invention relates to a line element with air gap insulation, in particular to a line element (10) for an exhaust gas line, for which an inner line (IS) is surrounded by an outer line (AS) formingan intermediate space (15). In a preferred embodiment, the inner pipe (IS) is produced from a strip (11) wound in a specific contour, which strip has at least one radial projection (RF) which projectsinto the intermediate space (15) as a distance holder between the inner pipe (IS) and the outer pipe (AS). 本发明涉及带有空隙隔绝的管路元件，具体而言，涉及一种用于废气管路的管路元件(10)，对该管路元件而言内部管道(IS)在形成中间空间(15)的情况下由外部管道(AS)围绕。在一种优选的实施形式中，内部管道(IS)由卷绕的成特定轮廓的带状物(11)制造，该带状物具有至少一个径向突起部(RF)，该径向突起部作为在内部管道(IS)和外部管道(AS)之间的间距保持件突出到中间空间(15)中。
