ASME B16.36 orifice flanges are used to measure the flow rate of liquids or gases which passes though the pipeline. ASME B16.36 orifice flanges are easy to install and are available I various sizes, grades and the combination of two orifice flanges are known as orifice flange union. Respective dimensions and specifications are provided which makes it easier to manufacture the services.
The ASME B16.36 Orifice Flange is available across different markets in sizes NPS 1 through NPS 24, whereas the pressure class rating of ASME B16.36 is as follows i.e. 300, 600, 900, 1500, and 2500.
Orifice flanges are the equivalent as weld neck flanges or slip on flanges. The differences are that these flanges have additional machining and have radial and tapped holes. This serves as the purpose of meter connections, which helps as jackscrews to provide for the detachment of flanges at the time of replacement of the orifice plate. Orifice flanges are generally used with orifice meters for better performance. This makes easy to measure the flow rates of oil, gas, and other fluids that have been conveyed in a pipeline. The standard assembly of orifice flanges involves gaskets, nuts, bolts, plugs, plates, a pair of flanges, and jacking screws. Jacking screws make removal of the primary flow element easier. When there is a requirement to connect a flow nozzle or an orifice plate, then ASME B16.36 orifice flanges are used instead of standard pipe flanges. Orifice flanges are available in different faces, such as RTJ (Ring Type Joint) facings and Raised Faces. The ASME B16.36 orifice flanges are the same as weld neck flanges.
Orifice flanges of ASME B16.36 are commonly manufactured by using various materials such as stainless steel, carbon steel, alloy steel, and many other suitable materials. Orifice flanges are also available in different ASTM forged grades, such as ASTM A350, ASTM A694, ASTM A105, and ASTM 182. These Flanges are also accessible in many dimensions, in socket weld, weld neck shape, and threaded type. These Flanges are widely used in many industrial applications by making them as per the demands of industries.
