Pipe bend for e.g. cross-sectional change of pipeline utilized for transporting bulk material, has multiple material strips running toward lateral lines of pipe sections to be produced, where material strips are curved and bent

摘要

The pipe bend (1) has material strips (2) running toward lateral lines (3) of pipe sections to be produced, where the material strips are curved and bent. The material strips are joined together to form a helix and exhibit different thicknesses. The material strips exhibit widths that are completely or partially different relative to each other. The material strips are made up of different materials. The material strips are connected along the lines by a detachable or non-detachable connection. A cross-sectional area formed from ends of the material strips forms a regular or irregular polygon.
