Concentric Reducer 12x8 Inch Flanged CS ASTM A234 GR B ASME B16.9 with A105N WN Flanges

Product Overview

This 12 x 8 inch concentric reducer is designed for industrial piping systems requiring a controlled transition between different pipe diameters. The fitting is manufactured from carbon steel ASTM A234 Grade B in accordance with ASME B16.9, while the supplied 12-inch and 8-inch flanges are weld neck carbon steel ASTM A105N conforming to ASME B16.5.

The concentric design maintains a common centerline, making it suitable for vertical lines and general process piping where symmetrical flow transition is required. Reference SPOOL 80-335-09 and drawing MD-JAL-6A-80-ME-736-02 Rev. 02 support project traceability and installation verification.
