Used with orifice meters for measuring the flow rate of gases or liquids in a pipeline, Orifice Flanges are similar to slip-on flanges or weld neck flanges but have extra machining. This extra machining adds pairs of pressure “Tappings” directly opposite each other, making separate orifice tappings or carriers in the pipe wall unneeded.
James Duva, Inc. supplies orifice flanges among other welded products. These units are durable and feature simple installation.
The orifice flange union is used to measure, or meter, the amount of pressure drop through the orifice plate.

This extra machining adds pairs of pressure “Tappings” directly opposite each other, making separate orifice tappings or carriers in the pipe wall unneeded.
Orifice Flanges generally come with either Raised Faces or RTJ (Ring Type Joint) facings. They are, for all intents and purposes, the same as weld neck and slip-on flanges with extra machining.
Flanges are available in Welding Neck, Slip-On, and Threaded form, and are typically supplied with two 1/2″ NPT tappings in each flange. The weld neck and threaded orifice flanges are manufactured in 300# and have larger pound ratings. However, the slip-on orifice flange is only available as a 300# raised face flange.
Precision
All orifice flanges are finished with alignment dowel pins which assure correct alignment of the flange bore within the tolerances of AGA-3.
Easy Installation
The orifice flange is a single component of the orifice flange union assembly. The orifice flange union is composed of two orifice flanges, an orifice plate, bolts, nuts, jack screws, and two gaskets and allows for easy installation for your project.
