Abstract

150,562. Mills, S. J. Nov. 1, 1919 Pipes and tubes.-Hollow metal bars, wires, or tubes are formed with one or more holes concentric or eccentric with the external surface of the bar, and each having a smooth and uniform capillary or other bore, by drilling or otherwise forming the initial holes in the billet, and after cleaning, filling them with clean well-fitting mandrels or cores, and forging, rolling, or drawing to reduce the size of the hole or holes. The billet and mandrels are then separated by reeling or axial rolling, and the rolling or like process repeated as often as necessary, the cores or mandrels being coated with silicate or like inert lubricating material if desired. The smooth clean holes thus formed may be further reduced by drawing.
