Butt weld fitting is used to changing direction of flow, to branch off, reduce pipe size or attach auxiliary equipment. Butt weld concentric reducers are manufactured in accordance with ANSI / ASME B16.9.
Butt weld concentric reducer is a component in a piping system that changes the pipe size from a larger to a smaller bore. Butt weld concentric reducer is used in various applications that involved in high pressure, vibration & temperature. They are widely used in chemical, petroleum, shipbuilding, gas, power sectors.
Carbon Steel Butt weld Reducers conform to ASTM A234. Stainless Butt weld Reducers conform to ASTM A403.

Purpose of Concentric Reducer
Butt weld concentric reducer is applied to join pipe sections or tube sections on the same axis. The concentric reducer is cone-shaped, and is used when there is a shift in diameter between pipes. For example, when a 1" pipe transitions into a 3/4" pipe and the top or bottom of the pipe doesn't need to remain level.
