Flanges are usually used to connect 2 pipes however, certain flanges also measure the flow rate of gas or liquid through the pipeline. One such flange is Orifice Flanges. It is used with an orifice meter for this purpose. This flange has a pair of pressure tapping on the opposite sides. ASME B16.36 Orifice Flangeis usually available in the raised face of ring type joint. Two orifice flanges that are joined together are known as orifice flange unions. Each ASME B16.36 flange comes with a tap for measuring the drop in pressure. They are installed in the straight rung of the pipe. This avoids turbulence at the plate.
Orifice Flange Standard help in measuring the flow rate of liquid in the pipe. They are a cost saving method when compared to other methods. This is because ANSI B16.36 eliminates the need of making bores on the pipe to insert instruments. It is reliable and provides an accuracy of the flow rate. They are easy to recognize since they have a hole drilled through the surface of the flange that assists in reading the pressure. Pressure tap While installation of ANSI B16.36 Orifice Flange needs to be at the same level. Pressure taps should not be installed facing downwards since it increases the risk of debris clogging the tap.
B16.36 Orifice Flange Dimensions depend upon the application that it is being used in. they are widely used in the paper industry, nuclear industry, heavy and light chemical industry, and petrochemical industry. B16.36 Orifice Flanges are said to be best suited for sewage treatment, power generation, and water treatment and distribution. They are also used in refining plants and oil production.
