Abstract
862,905. Making cored finned tubes. WELLINGTON TUBE WORKS Ltd. Oct. 15, 1959 [Oct. 21, 1958], No. 33545/58. Class 83 (2). A composite finned tube comprises an outer tube a of aluminium or aluminium alloy in which is expanded an inner tube b of a different metal, e.g. steel or copper, and an aluminium or aluminium alloy fin d secured in a helical groove c in tube a by squeezing the sides of the groove as by a rolling tool.
