Petropedia What Is An Orifice Valve Definition From An orifice is a small opening or hole in a plate or pipe or body when the fluid passes through the orifice the fluid flow gets restricted an orifice valve usually finds its application in areas where custody transfer has to take place from one party to other party Restriction Orifice Restriction Orifice Plate What Is Aug 15 2020 orifice plate is basically a thin plate with an orifice in the middle the plate is inserted between two flanges of a pipe for providing restriction or flow measurement purpose of restriction orifice restriction orifice is used primarily for two main reasons if there is a requirement of reduced flow or if there is a requirement of high Pdf Investigation Of Flow Inside Pulverized Coal Pc Therefore it is i mportant to place orifice at at the outlet of a roller mill installed in 660 mwe coalfired power plant flow in the pipe systems of coalfired power plants will lead to Orifice Meter An Overview Sciencedirect Topics An orifice meter consists of a flat plate that has a sharpedged hole accurately machined in it and placed concentrically in a pipe as shown in figure liquid flows through the pipe the flow suddenly contracts as it approaches the orifice and then suddenly expands after the orifice back to the full pipe
