ANSI B16.9 Carbon Steel SCH 20 Concentric Reducer  

A Buttweld Concentric Reducer is also called welded concentric coupling. It allows from connecting a large pipe to a smaller pipe by means of welding. A concentric reducer allows welded connection between two pipes with the same center line.In concentric reducers the area reduction is concentric and the centerline of the pipe on a bigger end and smaller end remains the same.  These styles are normally used for vertical lines. So in concentric reducers, the pipe axis remains the same. Reducers are reversible and can be used in any direction.In Concentric Reducer the reduction of the pipe size is achieved by decreasing the diameter of the fitting at a constant rate over a specified length, maintaining symmetry around the fitting. Concentric Reducers are used to join pipe or tube sections of different diameters on the same axis. They provide an in-line conical transition between pressurized pipes of differing diameters. Thus, concentric reducers connect pipes of uneq…
