Welded reducers are used for smooth transitions between pipes of different diameters. Available in concentric or eccentric designs, they adapt to various installation requirements and help reduce sudden changes in flow velocity and pressure loss. The welded connection provides stable pipeline strength, making them suitable for sanitary pipelines requiring long-term operation and frequent cleaning. Both the inner and outer surfaces are polished to meet DIN sanitary standards, and they can be used for pump inlet reduction, equipment transitions, and pipe conversions in asymmetrical layouts.
