The invention relates to a pipe fitting A, B, C, with a flange connector for joining at least two pipe ends of pipes that are arranged at an angle to each other. These pipe fittings are suitable for assembling a pipe system of any form with branch pipes and/or curves. The pipe system is suitable for assembly in the smallest space with short-radius curves, in any direction. According to the present invention at least one connector opening (1, 2, 11, 12, 13) of the curved fitting, comprises an annular edge flange (3, 4, 14, 15, 16). The flange projection and the concave curvature of the pipe fitting (A, C) are arranged so that a space remains for a clamp (F) to be installed on the flange (3, 4, 14, 15, 16). This clamp presses one edge flange against a counter flange. The outside configuration and the face of the edge flange are such that, not only is it possible to install a gasket between the faces but also, there is sufficient elasticity relative to the pipe mantle if the flanges are pressed together by the clamp (F). For this purpose there is a groove to accommodate the seal and an annular channel in the base area of the edge flange in the face surface which serves as a nominal bending point. (Figure 10). |
