Abstract

A corrugated pipe includes a corrugated pipe body circumscribing a hollow conduit and including alternating ribs and valleys extending along a longitudinal axis between a first end and a second end thereof. An electrically conductive wire is embedded in the corrugated pipe body, so that the wire spans adjacent ribs and valleys and extends substantially parallel to the longitudinal axis between the first and second ends.

First claim

That which is claimed is:

1. A corrugated pipe, comprising:
a corrugated pipe body circumscribing a hollow conduit, the corrugated pipe body comprising:
alternating outer ribs and outer valleys arranged on a corrugated outer surface of the corrugated pipe body and defining a corresponding corrugated inner surface including corresponding interior ribs and interior valleys; and
a ridge extending outwardly from the corrugated inner surface into the hollow conduit at the interior valleys corresponding to the alternating outer ribs wherein the ridge is unexposed on the outer surface.

2. The corrugated pipe of claim 1 , wherein the ridge; the alternating outer ribs and outer valleys; and the interior ribs and interior valleys are the same material.

3. The corrugated pipe of claim 1 , wherein a distance the ridge extends outwardly from the corrugated inner surface is consistent along a length of the corrugated pipe.

4. The corrugated pipe of claim 1 , wherein the ridge forms an elongated protrusion within the interior valleys that runs perpendicular to an annular surface of the interior valleys.

5. The corrugated pipe of claim 4 , wherein an apex of the ridge extends above an apex of the interior ribs.

6. The corrugated pipe of claim 5 , wherein a wire is embedded in the ridge.

7. The corrugated pipe of claim 1 , wherein the corrugated pipe is not double-walled pipe.

8. The corrugated pipe of claim 1 , wherein the corrugated pipe is not single-walled pipe.

9. The corrugated pipe of claim 1 , further comprising one or more additional ridges extending outwardly from the corrugated inner surface into the hollow conduit at the interior valleys.

10. The corrugated pipe of claim 1 , further comprising a wire within the ridge.

11. The corrugated pipe of claim 10 , wherein the wire is a steel wire.

12. The corrugated pipe of claim 11 , wherein the wire is a stainless steel wire.

13. The corrugated pipe of claim 10 , wherein the wire is a copper wire.

14. The corrugated pipe of claim 1 , wherein the ridge does not include a wire.

15. A corrugated pipe, comprising:
a corrugated pipe body circumscribing a hollow conduit and including alternating external ribs and external valleys extending along a longitudinal axis between a first end and a second end thereof; and
a ridge of a material forming the corrugated pipe body and comprising an elongated protrusion within interior valleys defined by an inner wall surface of the external ribs wherein the elongated protrusion is unexposed on the external valley.

16. The corrugated pipe of claim 15 , further comprising a steel wire within the ridge.

17. The corrugated pipe of claim 15 , wherein the elongated protrusion runs perpendicular to an annular surface of the interior valleys.

18. The corrugated pipe of claim 17 , wherein an apex of the ridge extends above an apex of an interior surface of the ribs.

19. The corrugated pipe of claim 15 , wherein the ridge does not include a wire.

20. The corrugated pipe of claim 15 , further comprising one or more additional ridges disposed within the interior valleys.
