MEDIA LINE

摘要

The invention relates to a media line, in particular for transporting urea-water solutions (1), comprising a tube line (2) for transporting media and optionally comprising at least one heating device, preferably a resistance heating wire that can be connected to a power source, for heating the medium (1). The tube line (2) is surrounded by a liquid-tight casing (4), preferably in some regions, said casing forming a gap (6) together with the tube line (2), wherein a secondary medium (5) which is preferably used for cooling the medium (1) can flow through said gap. The tube line (2) is connected to a functional device (12), through which the medium (1) can flow, in a liquid-tight manner, said functional device (12) being used to connect the tube line (2) to another element (18) and simultaneously to seal the end of the gap (6) in a liquid-tight manner.
