Welded reducers are used in SA piping systems to provide a smooth transition between pipes of different diameters. We offer both concentric and eccentric designs to accommodate different installation heights and drainage requirements. The internal transition utilizes a precise expansion and contraction process, resulting in more linear fluid flow within the pipe and reducing the risk of sediment buildup. They are commonly used at critical points requiring size transitions, such as pump inlets and the front end of filtration systems.
