WitrynaOrifice Flanges are used with orifice meters for the purpose of measuring the flow rate of either liquids or gases in the respective pipeline. Pairs of pressure “Tappings”, mostly on 2 sides, directly opposite each other, are machined into the orifice flange. This makes separate orifice carriers or tappings in the pipe wall unnecessary. WitrynaThe traditional orifice flange assembly consists of a pair of flanges, orifice plate, bolts, nuts, gaskets, jacking screws and plugs, (where requested). The flanges are generally weld neck design, but other options are available, such as Slip-on and threaded, although careful consideration should be taken in the location of the orifice tappings
