Abstract
A method of enhancing corrosion resistance of a hollow vessel. The method includes providing a hollow vessel including a wall defining a cavity, providing a coating tank filled with a liquid coating having charged coating elements, submerging the hollow vessel into the liquid coating, allowing the liquid coating to pass into the cavity through at least one aperture of the wall, coating the exterior surface of the wall with a portion of the coating elements, coating the interior surface of the wall with an additional portion of the coating elements, removing the hollow vessel from the coating tank, draining the liquid coating from the cavity, heating the hollow vessel in an oven, and curing the portion of the coating elements on the exterior surface and curing the additional portion of the coating elements on the interior surface.
