ABSTRACT:
A pipe bend for integration in a pipeline for conveying concrete has coupling flanges at the ends thereof which radially project beyond the outer surface of the pipe bend. The internal flow cross-section of the pipe bend is dimensioned essentially equal in any length portion of the pipe bend between the coupling flanges. The wall thickness of the radially outer bend portion facing away from the center of curvature increases in the conveying direction, wherein the internal flow cross-section has a ramp-like step in the radially outer bend portion at a distance from the end face of the pipe bend at the exit side corresponding approximately to twice the actual width of the coupling flange on the exit side.
