Abstract
1,173,031. Making bifurcated tubes. L. & C. STEINMULLER G.m.b.H. 2 Jan., 1967 [8 Jan., 1966], No. 109/67. Heading B3A. [Also in Division F2] A bifurcated tube is made by bending two straight tubes so that each has its ends 1, 2, 11, 12 relatively offset, cutting away half of the offset part (along the line II-II) and welding the two bent tubes together. The ends 1, 11 of the tubes may be drawn to a reduced diameter to give constant flow speed in pipes connected to the bifurcated tube, Figs. 3, a (not shown). The bending is performed in 4 tube bending press and preferably the tube is heated. The tube is cut by an oxygen torch and shaped by milling. Alternatively, the removal of the half-tube may be by milling. In an alternative embodiment each tube is bent so that the ends (1), (4), Fig. 5, are coaxial and the middle part of the tube is relatively offset. The part (5) is cut away (along line III-III) and the tubes welded together. The assembly is then cut (along line IV-IV) to form two bifurcated tubes. If the tubes have longitudinal fins these may be arranged to form a wall (16), (17), Fig. 12 (not shown), between the two legs 1, 11 of the bifurcated tube.
