Abstract

918,038. Making pipes and tubes; altering physical properties; extruding. ASHTON (DEVELOPMENTS) Ltd., N.C. Jan. 23, 1961 [Jan. 28, 1960], No. 2500/61. Divided out of 919,552. Classes 83 (2) and 83 (4). A copper nickel alloy is subjected to hot working, e.g. hammering or rolling at a temperature not exceeding 950‹ C. and continued down to a temperatufe of 750‹ C. to produce a deformation of at least 20% prior to a hot extrusion and then a cold drawing process. In an example an 8-inch diameter copper nickel alloy billet is hammered at 950‹ C. to 5-inch diameter machined to 4.7-inch diameter, drilled and extruded at 850‹ C. into a shell using a pressure of 2200 tons per square inch. The shell is processed into tubes by cold drawing.
