ABSTRACT:
In a process for hot-galvanizing finned tube, with the finned tubes being of varying geometry, coating with galvanizing media by flooding with such media in a galvanizing pan, the finned tubes automatically pass successively by a transport means consisting of horizontally and vertically mounted supporting, guiding, and driving rollers, and synchronous carrying chain through treatment stages including degreasing, rinsing, pickling, heating, galvanizing, cooling, drying, chromating, and blasting stages for mechanical tumbling/stripping/brushing means, so as to ensure, with additional parameters, the broadest possible range of application in consideration of the economy and requirements relating to environmental protection.
