The invention relates to a tube bend (1) having at least one bend area (1.1) and two discharge areas (1.2, 1.3) connected thereto on both sides. The tube bend (1) has a cross-sectional shape, with an identical flow cross-section 1.4, that differs from those of the outlet areas (1.2, 1.3). The degree of enlargement has, as a ratio of the diameter of the part in the bending plane to the diameter of the blank in the bending plane, a value ranging from 1 to 1.1.
