Concentric Reducer
A concentric reducer is a type of buttweld pipe fitting used to connect two pipes of different diameters while maintaining a common centerline. This design allows a smooth and uniform reduction in pipe size, ensuring balanced flow and minimizing turbulence. Concentric reducers are manufactured in accordance with standards such as ASME B16.9 and MSS-SP-43, and are available in carbon steel, stainless steel, alloy steel, duplex, and super duplex materials to suit various pressure and temperature requirements.
These reducers are widely used in industries such as oil & gas, petrochemical, power generation, chemical processing, and refineries, especially in vertical piping systems where proper flow symmetry is required. The tapered shape helps reduce stress concentrations and pressure loss, making concentric reducers ideal for high-pressure and high-temperature applications where reliable performance and long service life are essential.
