Concentric & Eccentric Reducers – Carbon Steel & Stainless Steel, SCH10 to SCH160, ½” to 36”
Description:
These Concentric and Eccentric Reducers are precision-engineered pipe fittings used to transition between different pipe sizes while maintaining consistent flow dynamics. Concentric reducers are ideal for vertical piping where fluid flow remains centralized, while eccentric reducers are used in horizontal runs to prevent air accumulation. Constructed from premium carbon steel (SA234 WPB) and stainless steel (SA403 WP304/316), these reducers are available in a wide range of sizes from ½ inch to 36 inches with wall thickness ratings from SCH10 to SCH160. Produced in Hebei China, Taiwan, and Korea, these reducers conform to international standards and are suitable for high-pressure, high-temperature systems across oil & gas, petrochemical, water treatment, and general industrial applications.
