The present invention relates to the coating of tubes, and more particularly to a system and method for renovating the inner surface of deteriorated or pitted tubes to extend tube life and enhance performance. A method of the present invention includes first providing a coating material in a tube.

The pig device is then motivated through the tube to apply the coating material to form a coating on the inner surface.
