Orifice Flanges are used with orifice meters for the purpose of measuring the flow rate of either liquids or gases in the respective pipeline. An orifice flange is used to measure the flow of the fluid conveyed by the pipeline via a flow nozzle positioned on the flange itself. Pairs of pressure tappings are machined onto the orifice flange, making separate tapings on the pipe wall unnecessary. The traditional orifice flange assembly consists of a pair of flanges, orifice plate, bolts, nuts, gaskets, jacking screws and plugs. Jacking screws ensure the easy removal of the primary flow element. When an orifice plate is crammed into the centre of a team of flanges during a pipe line connection, the entire procedure is referred to as an orifice flange amalgamation. An Orifice Flange is primarily used to provide access to a pipeline for gas or liquid metering. These flanges are provided in conjunction with appropriate test certificates for standard raw materials and finished products. Nascent fittings offer Orifice Flanges that can be customized in terms of thickness, size, and specification to meet our clients’ unique requirements. These flanges are available at competitive prices.
CARBON STEEL SPECIFICATION:
Orifice flanges are installed in a straight run of pipe in order to avoid turbulence at the plate. As a rule of thumb, an orifice flange has ten diameters of straight pipe upstream and five diameters of pipe downstream. Orifice flanges are generally used with orifice meters for better performance. This makes it easy to measure the flow rates of oil, gas, and other fluids that have been conveyed in a pipeline. The standard assembly of orifice flanges involves gaskets, nuts, bolts, plugs, plates, a pair of flanges, and jacking screws. Jacking screws make removal of the primary flow element easier.
