Key Features:

• Come with either raised faces or ring type joint (RTJ) facings.
• Available with raised face or RTJ face
• Used for flow/rate metering of piping systems
• Steel Tubes can supply the plate, pressure connection holes, and jack screws with the orifice flange unit
• The orifice flanges have modifications of radial tapped holes in the flange ring for meter connections. Need A Reliable Fitting?
• There are the orifice plate carriers in these flanges for the reason of fitting meter connections.
• The additional bolts available serve as a jack to allow the separation of the two flanges to change the orifice plate or for other relevant services like inspection.

Uses of orifice flanges: 

• Orifice flange is used to flow/rate metering of piping systems.
• They are used for all intensive purposes, similar to weld neck and slip-on flanges with extra machining.
