Abstract

A polymer tube for conducting a pipe buried underground, having a a plurality of RFID tags arranged at regular intervals along the tube and a protective layer of the RFID tags.

Claims

1. A polymer tube for conducting a pipe buried underground, said tube comprising:

the polymer tube;

a plurality of radio-tags arranged at regular intervals along the tube; and

a protective layer of said tags.

2. The polymer tube according to claim 1 wherein said radio-tags are situated on a ribbon wrapped around the tube.

3. The Polymer tube according to claim 1 wherein said radio-tags are located on a sheet of polymer before welding its ends to the tube.

4. The polymer tube according to claim 1 wherein said radio-tags are located on a continuous tape glued on one generatrix of the tube.

5. The polymer tube according to claim 1 wherein said radio-tags are directly glued after pre-forming.

6. The polymer tube according to claim 1, further comprising a protective polymer layer protecting said radio-tags during bending and packaging of the tube and the operations involved before and during installation.

7. The polymer tube according to claim 1, comprising communication means for communicating identity, characteristics relevant to the manufacturing process of the tube and the localization of the tube.

8. The polymer tube according to claim 7 wherein it is adapted to the realization of a water distribution pipeline (e.g. drinking water) or gas, or for protecting an electric wire or optical fiber.

21. The polymer tube according to claim 1 wherein said radio-tags are located within a separate package which can be clamped, screwed, glued or welded on the tube.

9. A method of manufacturing a tube of polymer dedicated for an underground pipeline, said method comprising the steps:
