Abstract
A method and system for manufacturing a hairpin tube. The method includes cutting a coil of tube to provide a plurality of lengths of tubes, and bending each length of tube to form a plurality of hairpin tubes. A lubricant is then atomized with an injector nozzle, and injected into at least one open end of each hairpin tube. After lubricating the hairpin tubes, the legs of each hairpin tube are expanded.
