Abstract
A double-layer pipe bend for a pipeline includes an inner pipe of cast steel, an outer pipe of weldable steel surrounding the inner pipe, and connecting flanges at the ends of the pipe bend. The connecting flanges are welded to the outer pipe. The inner pipe and the outer pipe are formed such that a pressure-compensating layer can be formed by the transported medium between the pipes. Another pressure-compensating layer can form between an inner wearing ring and an outer coupling ring of each connecting flange. The wearing ring and, thus, the inner pipe is axially secured by a groove in the wearing ring and a radial collar in the coupling ring.
