Abstract

A fluid line with a pipe provided with a sleeve of a woven or braided fabric, wherein the pipe, in turn, includes at least one conductor. In the finished state of the fluid line, the sleeve immediately surrounds the pipe and each conductor is loosely arranged in the sleeve. In accordance with another embodiment, the at least one conductor forms the sleeve.

Claims (15)

1. A fluid line comprising a pipe with a sleeve of a woven or braided fabric, wherein the woven or braided fabric includes at least one conductor, wherein, in a finished state of the fluid line, the sleeve immediately surrounds the pipe and the at least one conductor is loosely arranged in the sleeve wherein the at least one heating conductor comprises an electrical heating wire, wherein the heating wire is arranged in insulating material, and wherein the insulating material comprises a glass fiber bundle around which each heating wire is helically wound, and a flexible plastic layer surrounding the heating wire and the glass fiber bundle.

2. The fluid line according to claim 1 , wherein the sleeve surrounds the pipe and is outwardly exposed.

3. The fluid line according to claim 1 , wherein each heating conductor is woven into the sleeve and is partially in contact with the pipe through the material of the sleeve.

4. The fluid line according to claim 1 , wherein the sleeve is composed of glass fibers, plastic fibers, natural fibers, carbon fibers, mineral fibers or metal fibers.

5. The fluid line according to claim 1 , wherein the at least one conductor is straight or coiled.

6. The fluid line according to claim 1 , wherein the at least one conductor is wound helically around the pipe.

7. The fluid line according to claim 1 1 , wherein the at least one heating wire is arranged helically in an elongated insulating material.

8. The fluid line according to claim 1 , wherein the pipe is smooth or corrugated.

9. The fluid line according to claim 1 , wherein the sleeve is arranged loosely on the pipe.

10. The fluid line according to claim 1 , wherein the at least one conductor is slidable in longitudinal direction in the sleeve.

11. The fluid line according to claim 1 , wherein the sleeve is attached to at least one location to the pipe.

12. The fluid line according to claim 1 , wherein the sleeve is surrounded by a protective sleeve.

13. The fluid line according to claim 12 , wherein the protective sleeve includes thermoplastic material and the protective sleeve is arranged, injected or extruded onto the sleeve.

14. The fluid line according to claim 1 comprising a pipe of flexible material, and a conductor arranged in the material, wherein a current can be conducted through the conductor for changing the temperature of the fluid in the fluid line, and wherein an outer side of the pipe has a groove, and the conductor is arranged in the groove.

15. The fluid line according to claim 14 , wherein the groove is undercut, so that the conductor can be engaged in the groove.
