Orifice Flanges

Orifice Flanges are used to meter the volumetric flow rate of liquids or gases utilizing tapped or welded meter connections. The two pipe taps are used to measure the pressure drop of the flow through an Orifice Plate.

  • Available in RF (Raised Face) or RJT (Ring Type Joint) configurations – Welding Neck / Slip-On / Threaded
  • Supplied with two 1/2" NPT tappings in each flange
  • Lambda Square Orifice Flange Unions are fabricated to ASME B16.36 requirements
  • Our Orifice Flange Union kits are available ready-to-install, complete nuts, bolts, screws, and gaskets

Unlike a standard orifice plate, the ORIPAC is a true primary element and includes components for differential pressure measurement.
