Asme Flange

Class 300, Welding Neck, Slip-On and ThreadedB16.47, Ser. A ASME B16.5 Flanges Weld Neck, Slip-On, Socket Weld, Threaded, Lap Joint, Blind. 1/2" - 24" Class 150, 300, 400, 600, 900, 1500 and 2500 NOTE: Reducing flanges are available in all types and pressures. To order a reducing flange, state the smaller size first, then the outside diameter of the larger size. Example: 1" X 71⁄2" O.D. 150 SO RF reducing would be a 3" X 1" Slip-on, Raised Faced Reducing. Or, to simplify, just state the actual pipe sizes in order of larger to smaller. Example: 3" X 1" Slip-on, Raised Faced, Reducing.
