A conveying pipe for hydraulically transporting solids, such as sand, gravel or also concrete is composed of a straight or curved pipe portion and of coupling flanges at the ends of the pipe portion, wherein the coupling flanges protrude radially above the outer surface of the pipe portion. The outer end faces of the coupling flanges which face away from each other are each located in the transverse planes of the end faces of the conveying pipe. The coupling flange located at the end of the conveying pipe on the inlet side has a greater width than the coupling flange arranged at the end on the outlet side.
