Pipe and pipe connection element for gas and water supplies

摘要

The pipe element (1) comprises a cylindrical pipe section (2) with a ring flange (3) defining a flange edge (5). The angle ( alpha ) between the normal (4) of the flange surface and a longitudinal central axis (6) of the pipe section is greater than zero, and either 12.5 deg or 25 deg . The inner cross-sectional diameter of the flange edge corresponds to the inner cross-sectional area of the pipe section.
