Abstract
A method is provided for electrodepositing a coating a conductive workpiece. The method provides for individually switching on or off electrodes both interior to and exterior to the workpiece so as to control the deposition of the coating material on the interior surface and the exterior surface of the workpiece. Further, an electrode having insulating positioners can be utilized to provide for better centering of the electrode in the interior of the workpiece.
Claims4
An electrode for use in the interior of a pipe to be coated with a coating material in an electrodeposition process, the electrode comprising:
- a conductive member having a length;
- a plurality of insulating positioners connected to the conductive member and spaced along the length of the conductive member, wherein each insulating positioner has a breadth perpendicular to the length of the conductive member at the position it is connected thereto, and the breadth is approximately equal to the internal diameter of the pipe.
