Abstract

Claims (29)

1. A method of forming a wired pipe transmission line comprising:

providing an assembly that includes insulating material disposed about an inner conductor;

surrounding the insulating material with a shield layer to form a transmission cable;

forming mating features in the shield layer;

disposing the transmission cable within a wire channel;

disposing a fixation element between the shield layer and the wire channel; and

fixedly attaching the fixation element to the wire channel by welding the wire channel and fixation element together.

2. The method of claim 1 , wherein forming mating features in the shield layer occurs before the insulating material is surrounded by the shield layer.

3. The method of claim 1 , wherein forming mating features in the shield layer occurs after the insulating material is surrounded by the shield layer.

4. The method of claim 3 , wherein forming mating features in the shield layer includes forming mating features on an outer surface of insulating material.

5. The method of claim 3 , wherein the mating features are threads.

6. The method of claim 5 , wherein the disposing a fixation element between the shield layer and the wire channel includes threading the fixation element on to the transmission line.

7. A method of creating a wired pipe segment having first and second ends comprising:

disposing a first coupler in the first end of the wired pipe segment;

disposing a second coupler in the second end of the wired pipe segment;

forming a wired pipe transmission line, comprising:

providing an assembly that includes insulating material disposed about an inner conductor;

surrounding the insulating material with a shield layer to form a transmission cable;

forming mating features in the shield layer;

disposing the transmission cable within a wire channel;

disposing a fixation element between the shield layer and the wire channel; and

fixedly attaching the fixation element to the wire channel by welding the fixation element to the wire channel;

placing the transmission line in the wired pipe segment; and

connecting the transmission line to the first and second couplers.

8. The method of claim 7 , wherein the mating features in the shield layer comprise threads.

9. The method of claim 8 , further comprising forming threads on an inner surface of the fixation element.

10. The method of claim 7 , further comprising:

forming a thread on an outer surface of the insulating layer; and

mating the wire channel to the insulating layer with the thread on the outer surface of the insulating layer.
