Advantages of concentric reducers include providing a smooth flow transition, helping to avoid cavitation, and maintaining symmetry in the reduction of pipe diameter. Concentric reducers are not suitable for use in horizontal liquid piping to avoid the formation of cavitation pockets as compared to eccentric reducers. When selecting concentric reducers, consider the size of the pipe being connected, material compatibility with the fluid being communicated, pressure requirements, and particular application needs.
Concentric reducers are fittings used to connect pipes of different sizes and are developed to feature a progressive shift from larger to smaller diameters, preserving a common centerline. These fittings are commonly used in piping systems where they are required in vertical flow applications or as reducers in horizontal layouts.
