ASTM A815 Duplex 2205 / UNS S32205 Buttwelding Duplex Steel Eccentric Reducer
Duplex Steel S32205, also known as Duplex 2205, is a stainless steel alloy that combines both austenitic and ferritic properties, making it versatile for various applications. An eccentric reducer is a type of fitting used in piping systems to connect two pipes of different diameters. Unlike concentric reducers, which have a symmetrical shape, eccentric reducers have one side flat, allowing for better drainage and a more streamlined flow in certain applications. They are commonly produced in sizes ranging from 3/4 inch to 24 inches in diameter with wall thickness available from Sch 10 to Sch 160.
Concentric Reducer vs. Eccentric Reducer
| Shape and Design | Concentric Reducer: Shape: Both ends are centered on the same axis. It transitions uniformly from a larger to a smaller diameter. Use: Commonly used in systems where the flow direction is maintained and space allows for the circular shape. Eccentric Reducer: Shape: One end is off-center, creating a sloped angle between the larger and smaller diameters. Use: Often used in horizontal piping systems where the top of the pipe is critical for flow (like drainage) or to prevent air pockets. |
| Flow Characteristics | Concentric Reducer: Reduces flow with a smooth transition, minimizing turbulence. Eccentric Reducer: Can create situations where liquid flow is disrupted if not properly installed, but allows for better drainage and air elimination. |
| Application | Concentric Reducer: Best for vertical applications or where the flow is not likely to trap air. Ideal for fluid transport where maintaining a consistent flow path is needed. Eccentric Reducer: Used when transitioning between horizontal and vertical pipes to avoid trapping air. Helps maintain a constant flow in horizontally oriented piping systems. |
