Orifice Flanges
An Orifice Flange is used with orifice meters, which in turn are designed with the purpose of measuring the flow rate of media i.e. which could either be fluids or it could be gases in the respective pipeline. There are pairs of pressure Tappings, that are directly placed and machined opposite each other, on to the Orifice Flanges. These tappings are mostly on 2 sides of the flanges. The orifice plate in the orifice plate weld neck flange contains a small hole. Two pressure tap holes are generally drilled in each flange which helps the worker minding the piping system to measure the pressure built inside the pipe. A jackscrew fitted between the two api 6a orifice flange.
