ASME B16.9 Eccentric Reducer

An ASME B16.9 Eccentric Reducer is a pipe fitting designed to connect pipes of different diameters, while maintaining an eccentric alignment. Unlike concentric reducers, which have a symmetrical center, eccentric reducers have an offset center, allowing for a smoother transition in systems where a flat bottom is necessary, such as in pump suction lines. This design prevents air pockets and ensures proper flow in various industries, including oil and gas, petrochemical, and water treatment.

We specialize in manufacturing high-quality ASME B16.9 Eccentric Reducers in various sizes and materials, ensuring precise dimensions and outstanding performance. Our reducers are produced using advanced technologies and strict quality control standards to provide durable, reliable products that meet client specifications and industry standards.
