The invention relates to a tube bend (10) as a constituent part of a conveying line for abrasive thick matter, such as liquid concrete. The tube bend (10) has an inlet opening (12) and an outlet opening (14) which communicates via at least one curved part (18) with the inlet opening (12) and is angled off axially or arranged in an offset manner with respect to the inlet opening (12). A particular feature of the invention is that the curved part (18) has, at least in a curved section adjoining the inlet opening (12), a constantly increasing curvature along the centre longitudinal axis (24) thereof, wherein the curved part (18) expediently has a constant passage cross section over the length thereof. The curved part (18) expediently has a decreasing curvature in a curved section surrounding the outlet opening (14). |
