Abstract

406,498. Gilled tubes for heat exchangers. MANUFACTURE GENERALE METALLURGIQUE SOC. ANON., 97, Avenue Louise, Brussels. April 10, 1933, No. 10688. Convention date, April 12, 1932. [Class 64 (iii).] A method of producing gilled metal tubes consists in threading upon the tubes gills of a more resilient metal than the tubes and expanding the tubes so that upon release of the expanding force the gills grip and form constrictions in the tubes. The tubes, e.g. of annealed red copper, may be provided with gills of hardened aluminium or aluminium alloy and expanded by a split or solid mandrel c. Alternatively, a mandrel e, Fig. 3, having an expansion wedge f is employed.
