Abstract

"Chemical process to improve the qualities of aluminum tubes", characterized in that it consists of insulating the interior and exterior surfaces after the operations of degreasing the interior and exterior of the tube; also chromatize the interior and exterior; internally coated by spraying with asphaltic phenol varnish or similar resin with adequate thickness and sufficient to withstand high temperatures. Externally coat the tube with powder epoxy-thermosetting resins, applied electrostatically or by a similar procedure and curing said resins in a convection oven at a temperature of 200 degrees centigrade for the appropriate time.
