ASTM A182 F316/316L Orifice Flange 1/2" (15 NB) to 48" (1200NB) 600 LBS Forged
Orifice Flange Installation
Orifice flanges are installed in a straight run of pipe in order to avoid turbulence at the plate. As a rule of thumb, an orifice flange has ten diameters of straight pipe upstream and five diameters of straight pipe downstream. In general pressure taps kept at the same elevation to each other.

1. Orifice Flanges are used with orifice meters for the purpose of measuring the flow rate of either liquids or gases in the respective pipeline. They are, for all intensive purposes, the same as weld neck and slip-on flanges with extra machining. Orifice flanges may be provided in one of three types of flanges: Welding Neck, Slip-On and Threaded.
