Orifice Unions are ready to install assemblies used to measure and control flow or to reduce pressure in a pipe system. They are comprised of Gaskets, Hardware and Orifice Flanges that contain pressure sensing ports. An orifice plate is also typically used with the orifice union. Once installed (welded in line), connect your dP flow transmitter and you are ready to measure flow. Configurations of this assembly are adaptable to almost any line conditions. Components that comprise the assembly can be precisely specified for any application, with carbon steel flanges and a stainless-steel orifice plate being the most common variation.
