Abstract
An electroplating apparatus applies an electroplated coating to a female thread formed on a pipe end portion of a steel pipe. The apparatus includes an inner seal member, a capsule, a discharge outlet, an opening, a cylindrical insoluble anode, a plating solution supply tube, and a plurality of nozzles. The seal member divides the interior of the steel pipe at a location longitudinally inward of a region on which the female thread is formed. The capsule is attached to the pipe end portion. The outlet is designed to discharge a plating solution inside the capsule therefrom. The opening facilitates discharge of the solution inside the capsule. The anode is disposed in the inside of the pipe end portion. The supply tube projects from an end of the anode. The nozzles eject a plating solution between the outer surface of the anode and the inner surface of the pipe end portion.
