HEATABLE FLUID LINE, USE THEREOF AND METHOD FOR PRODUCING SAME

摘要

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 than the material of the first longitudinal section (2a, 202). The described method for producing such a fluid line according to the invention relates to an adaptive attachment of the heating conductor (3, 224) on the outside of the pipeline (2, 218) which permits the heating conductor (3, 224) to be wound around fluid coupling and/or connector parts, in particular the housings thereof (14, 15, 16, 17, 21, 22, 33, 34, 50, 51, 52, 53, 206, 208, 210, 212, 230, 232, 244, 246) by means of which the line (1) is assembled, without strand separation.
