FPD160 weld-in orifice flange unions/assemblies for flow measurement

Weld-in Orifice Flange Unions/Assemblies to fit between RF, FF or RTJ flanges. Orifice flanges include the DP tapping points and are supplied with the necessary orifice plate, gaskets, nuts, bolts and 9IBA028556_400x400jacking screws, designed to measure the flow of clean or contaminated liquids, gases or steam.


The ABB FPD160 is a range of flow measurement orifice plates fitted into weld-in orifice flange unions with flange tappings.  The orifice plates are available with a variety of profiles to handle a wide range of applications, from clean fluids and low viscosity liquids through to dirty fluids or high viscosity liquids.
Orifice Plate designs:
– Concentric square-edge orifice plate for clean liquids/gases/steam
– Quarter circle orifice plate for viscous fluids
– Conical entrance orifice plate for viscous fluids
– Eccentric orifice plate for dirty fluids
– Segmental orifice plate for dirty fluids
– Orifice plate in holder between RTJ orifice flanges
