Product Details
"NRG GOBAL INSTRUMENTS" make "ORIFICE FLANGE ASSEMBLIES" are used for measuring flow of various Liquids, Gases & Steam from 2" to 32" line sizes. It gives an acceptable level of uncertainties at lowest cost and long life without regular maintenances. Orifice Plates are most commonly used as primary element for flow measurement in pipelines based upon the principle of measurement of ‘Differential Pressure' created when an obstruction is placed in the fluid flow, due to increase in fluid velocity. The orifice plate dimension is based on BS/ISO- 5167specification. OPERATING PRINCIPAL When fluids/gas is flowing from main pipeline. Orifice plate restricts the flow and develops the Differential Pressure which is proportional to the square root of the flow rate. DESIGN The 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. Weld neck Orifice Flange Assemblies: Weld neck orifice flanges are butt-welded into the pipeline. The inside diameter (or the schedule) of the pipe should be specified when ordering. Weld neck orifice flanges are available in classes 150,300 & 600. Raised face (RF) and ring type joint (RTJ) versions can be supplied. ORIFICE PLATE FLANGE ASSEMBLY COMPONENT: The orifice – flange assembly consists of a mainline Orifice plate, a set of Orifice Flanges. This plate is sandwiched between two Orifice Flanges. Tag Plate of orifice plate projects out from Orifice flanges and it indicates the existence of Orifice plate. Details such as Tag NO /Orifice ID / Pipe ID / Plate Material are stamped on one side of the tag plate which faces upstream side of the pipe line.
