A heatable fluid line having a pipeline and an electrical heat conductor extending at least over a section of the pipeline. The pipeline has at least two longitudinal sections that are configured differently in respect of the material properties and/or design thereof. At least one first longitudinal section is formed of a first material and a second longitudinal section is formed of a second material. The material of the second longitudinal section is more flexible and/or has a higher resilience than the material of the first longitudinal section. A described method for producing the fluid line relates to an adaptive attachment of the heat conductor on the outside of the pipeline that permits the heat conductor to be wound around fluid coupling and/or connector parts, in particular the housings by means of which the line is assembled, without strand separation.

Heatable fluid line, use thereof and method for producing same

For a heatable medium pipe having at least one pipe connector and heating element, wherein the heating element has a few wires, in particular one or two wires, wherein the wire(s) extend continuously along the medium pipe and along the at least one pipe connector. In a method for producing a heatable medium pipe, comprising the medium pipe, at least one pipe connector, a transition area between the medium pipe and the pipe connector, and at least one heating element, wherein the heating element has a few wires, in particular one or two wires, the medium pipe is pre-assembled with the at least one pipe connector, the wire or the few wires of the heating element are pre-assembled as a double-laid, one or two-part element or as an element connected to form a continuous part, the wire(s) are fastened on the outside of the pipe connector, transition area and medium pipe, and the ends of the wire(s) are guided into a feed-in connector for connecting to a current source or voltage source.

Heatable medium pipe

A heatable medium pipe having at least one pipe connector and heating element, wherein the heating element has a few wires, in particular two wires, and said wires extend continuously along the medium pipe and along the at least one pipe connector. In a method for producing such a heatable medium pipe, the heating element is continuously wound around a tubular medium pipe and the heating element is pre-assembled on the medium pipe in that the heating element is fastened or fixed by at least one fastening element, the medium pipe is cut to a first length for the particular application, the length corresponding to the desired medium pipe length (l) plus the heating element length (l) required for wrapping around the at least one pipe connector and the transition area the fastening element is removed in the region outside the desired medium pipe length (l), the heating element is unwrapped from the medium pipe section cut from the first length, the medium pipe is cut to the desired medium pipe length (l) to form a second medium pipe section, the medium pipe section is connected to the at least one pipe connector as the medium pipe, and the heating element is at least wrapped around the at least one pipe connector.
