Orifice Flanges

Orifice Flanges are used with orifice meters to measure the flow rate of liquids and gases in a pipeline. They are similar to Welding neck, Slip-On and Screwed Flanges, except that they are modified to hold orifice plate carriers and have radial taped holes for the fitting of meter connections.
