Orifice Flange

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.
