Abstract

853,574. Making screw-threaded tubes. MINING ENGINEERING CO. Ltd. Dec. 3, 1957 [Dec. 11, 1956], No. 37773/56. Class 83 (2). In a method of mak. ing tube having an internal thread, Fig. 1, a member or members of suitable shape, e.g. a bar 10 and an inter. mediate strip 11 are coiled helically and the meeting edges welded. The helices are coiled on a mandrel to maintain concentricity and axial pressure is applied to hold the meeting edges together during welding. The strip and bar may be integral, the required T or L section being produced by rolling. Specification 783,783 is referred to.
