Webrequired to have two pressure taps - one in each flange. Usually, an extra set of pressure taps is provided and located 180° from the first required pair. The pressure taps are 1/2” NPT with a through hole of either 3/8” or 1/2” diameter, depending on the nominal flange size. Figure 1. Example Orifice Flange Union (OFU) WebBased on flange rating per ANSI B16.5 Pipe sizes 2-in. to 24-in. (50 mm to 600 mm). Contact Emerson Process Management for pipe sizes less than 2-in. (50 mm) or greater than 24-in. (600 mm). Operating limits 1495 Temperature Range –320 to 1200 °F (–196 to 649 °C) Physical specifications Rosemount 1496 Orifice Flange Union

WebThe most popular taps are flange taps and radius taps. For pipes having a diameter greater than 2 inches, flange taps are positioned one inch upstream and one inch … WebASME (2001) suggests 1.2 cm ≤ D ≤ 4 cm for corner taps and 2.5 ≤ D ≤ 4 cm for flange taps. Diameter ratio d/D LMNO Engineering and ASME (2001) require 0.1 ≤ d/D ≤ 0.8 for corner taps and 0.15 ≤ d/D ≤ 0.7 for flange taps. Reynolds number based on pipe diameter ReD LMNO Engineering and ASME (2001) require ReD ≥ 1000. Expansibility e sharla thomas
