Abstract

1462370 Making internally finned tubing; corrugating tubes UNITED KINGDOM ATOMIC ENERGY AUTHORITY 11 Nov 1974 [30 Nov 1973] 55745/73 Headings B3A and B3E A method of forming one or more fins in the bore of a tube 2 comprises deforming the wall of the tube using one or more forming tools and causing relative movement between the tool or tools and the tube to form one or more grooves 3 in the outer surface of the tube and a corresponding protrusion or protrusions in its bore, and working the tube at least partially to close up the or each groove and cause the or each protrusion to be pushed inwardly into the bore to form a fin. The tube 2 is held by a clamp 12 and supported internally on a mandrel, both the clamp and the mandrel being free to rotate about the tube axis. Tube-deforming wheels 5 are adjusted relative to the tube axis, locked by set screws 10 and pressed down on to the tube by tightening screws 9. The tube 2 is then moved longitudinally and the wheels 5 form helical indentations in its surface, which are pressed into corresponding grooves in the mandrel. The tube is subsequently worked in a rotary ball or hammer type swaging machine. Alternatively it may be passed through reducing dies or rolls.
