Toneable conduit and method of preparing same

A toneable conduit, comprising:

• an elongate polymeric tube formed of high density polyethylene having a wall with an interior surface, an exterior surface, and a predetermined wall thickness;
• a channel extending longitudinally within the wall of the elongate polymeric tube;
• and a stabilizing rib extending longitudinally along the interior surface of the wall of the elongate polymeric tube and located radially inward from said channel;
• and
• a continuous, copper-clad steel wire coincident with the channel in the elongate polymeric tube, said copper-clad steel wire coated with polytetrafluoroethylene to prevent the wire from adhering to the polymer melt used to form the polymeric tube;
• said copper-clad steel wire capable of transmitting a toning signal over long distances to allow the conduit to be detected by toning equipment and capable of being torn out of the polymeric tube and remaining continuous to allow the conduit and wire to be coupled.

A toneable conduit, comprising:

• an elongate polymeric tube having a wall with an interior surface and an exterior surface;
• and a first channel extending longitudinally within the wall of the elongate polymeric tube;
• and
• a continuous wire coincident with the first channel in the elongate polymeric tube;
• said continuous wire being a toning signal wire allowing the conduit to be detected by toning equipment and said wire capable of being torn out of the polymeric tube and remaining continuous to allow the conduit and wire to be coupled.

A toneable conduit, comprising:

• an elongate polymeric tube having a wall with an interior surface, an exterior surface, and a first channel extending longitudinally within the wall of the elongate polymeric tube;
• and
• a continuous wire having a tensile strength of at least about 150 lbs coincident with the first channel in the elongate polymeric tube;
• said continuous wire being a toning signal wire allowing the conduit to be detected by toning equipment.
