Orifice Flanges are widely used in conjunction with orifice meters for measuring the volumetric flow rate of liquids and gases through a pipe. Two orifice flanges are called an orifice flange union. Each flange comes with a pipe tap for measuring the PRESSURE DROUP of the flow through an orifice plate. This makes separate orifice carrier or tapping in the pipe wall unnecessary. Orifice plates do not come with the flanges and are sized based on the requirements of the process. One / Two jack screws are used to spread the flanges apart in order to change the orifice plate.
