ORIFICE FLANGES are widely used in conjunction with
orifice meters for measuring the rate of flow of liquids and
gases. They are basically the same as standard welding
neck and slip-on flanges except for the provision of radial,
tapped holes in the flange ring for meter connections and
additional bolts to act as jack screws to facilitate separating
the flanges for inspection or replacement of the orifice plate.
