Beschreibung
Zusammenfassung:	The invention relates to a heatable fluid line (1) comprising at least one pipeline (2, 218) and at least one electrical heating conductor (3, 224) extending over at least a partial section of the length (L) of the pipeline. In order that the fluid line (1) fulfills increased requirements in respect of resistance to high temperatures, compensation of pressure pulsations and/or compression resistance, while being less complex to produce and assemble and/or connect, according to the invention the pipeline (2, 218) has at least two longitudinal sections (2a, 202, 2b, 204) which are designed differently in respect of the material properties and/or design thereof, namely at least one first longitudinal section (2a, 202) which consists of a first material which comprises a first polymer and a second longitudinal section (2b, 204); which consists of a second material which comprises a second polymer, wherein the material of the second longitudinal section (2b, 204) is more flexible and/or has a higher resilience tha
