Green pipes, raw steel tubes, are processed through a number of steps to make them into drill pipes. First, the walls of green pipes are thickened by a process called upsetting through which a pipes exterior surface is pushed inward. Next, the pipes are threaded and receive a strength-enhancing copper plating.
