Orifice Flange

An orifice flange is a unique flange in piping systems and flow measurement. It's made to fit an orifice plate, which is a device with a precisely sized hole that controls fluid flow. It is essential for precise measurement of fluid flow rates in pipelines carrying liquids and gases. Orifice flanges are applied for metering the volumetric flow rate of liquids and gasses through a pipe. Two orifice flanges are called an orifice flange union. Each flange comes with two pipe taps for measuring the pressure drop of the flow through an orifice plate.
