Abstract
A method for making a wired drill pipe joint includes forming an electrically conductive material into a structure that is radially expandable to conform to an interior of the pipe joint substantially without plastic deformation of the electrically conductive material. An electrical connector is coupled to each longitudinal end of the formed electrically conductive material to form an electrical conductor assembly. An interior of the pipe joint is coated with an electrically insulating material. The electrical conductor assembly is inserted into the pipe joint. The electrically conductive material is radially expanded to conform to an interior surface of the pipe joint wherein a bonding material is applied to the interior wall of the pipe joint.

A method for making a wired drill pipe joint, comprising:
- forming an electrically conductive material into a conduit structure, the conduit structure being internally hollow, radially expanding the conduit structure to conform to an interior surface of the wired drill pipe joint substantially without plastic deformation of the electrically conductive material, the conduit structure longitudinally contractible corresponding to radial expansion;
- coupling an electrical connector to each longitudinal end of the conduit structure to form an electrical conductor assembly;
- coating an interior surface of the wired drill pipe joint with an electrically insulating, bonding material;
- inserting the electrical conductor assembly into the wired drill pipe joint;
- and
- radially expanding and correspondingly longitudinally contracting the electrically conductive material of the electrical conductor assembly to conform to the interior surface of the wired drill pipe joint.
