Our orifice flange is used with orifice meters to measure
the flow rate of liquid and gas. Two orifice flanges with
bolts and jack screws are referred to as an orifice flange
union, which is used in conjunction with an orifice plate.
Compared with weld neck flange and slip on flange, it is
provided radial, tapped holes in the flange ring for meter
connections and additional bolts to facilitate separating
the flanges for inspection of the orifice plate.
