Abstract

762,320. Making cased gilled tubes; jointing by tube expanding. WELLINGTON TUBE WORKS, Ltd. June 23, 1955 [June 25, 1954], No. 18661/54. Classes 83 (2) and 83 (4). [Also in Group XXVIII] A method of securing gills to a composite metal tube of the kind having inner and outer parts of different metals comprises securing the gills c, of, for example, aluminium alloy, to the outer tube part a, of, for example, aluminium alloy, by expanding the latter into engagement with the gills, and subsequently inserting the inner tube part b, of, for example, cupro-nickel, and securing it by expanding it within the outer tube part a. The tubes are expanded by drawing a mandrel therethrough.
