ASME B16.9 Concentric / Eccentric Reducer Dimensions (mm)
The reducers are often used when the piping designers want to reduce the diameter of a straight run of pipe. There are two styles of standard reducers available in ASME B16.9: Concentric – having a common centerline; Eccentric reducer – having offset centerlines.
