Systems, methods, and devices for perforating louver perforations into a pipe are contemplated. Systems, methods, and devices for transporting pipes for perforation are contemplated. Systems, methods, and devices for performing quality control inspections of such perforations contemplated. A pipe may be oriented vertically and raised over a device that punches perforations into the pipe from the inside of the pipe toward the outside of the pipe. Various supports may contact the pipe for stabilization and to facilitate the formation of perforations without removing cut away pieces from the pipe. Electronic monitoring of the features of the pipe facilitate quality control inspection during processing. In this manner, a structurally robust pipe having a series of louver perforations along the pipe may be formed.

A method for fabricating a segmented electrode is provided. The method includes performing a series of progressive die stamping operations on a foil sheet of material to form an initial electrode, and removing portions of the initial electrode using a centerless grinding process to form a segmented electrode including a plurality of circumferentially spaced contacts.
