What is an Orifice Flange?

An Orifice Flange is a disc-shaped flange, engineered with either a Raised Face or a Ring Type Joint facing. The traditional Orifice Flange assembly consists of a pair of flanges, orifice plate, bolts, nuts, gaskets, jacking screws and plugs. Advance Forging ensure the easy removal of the primary flow element.

An Orifice Flange is used in combination with orifice meters to measure the flow rate of oil, gas and other liquids conveyed by the pipeline. Orifice flanges are manufactured to ASME B16.36 in multiple sizes and, material grades. 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. An Orifice flange is a disc-shaped flange, engineered with either a Raised Face or a Ring Type Joint facing.

How does an Orifice Flange work?

The function of the orifice flange is to measure the rate of the flow of the commodity through the piping system. Orifice flanges are easy to recognize because they have a hole drilled through the face of the flange perpendicular to the pipe. They also have an additional set of bolts called jack screws.

Advance Forging is reckoned amongst the prominent in Orifice Flanges Manufacturer. ASME B16.36 flanges are orifice flanges and they are used for measuring the flow of fluid that has been transported through a pipeline, via a flow nozzle, that has been kept on the flange. Orifice flanges of ASME B16.36 can be obtained from Class #300 – Class #2500. Orifice Class #300 flanges are procurable in types such as weld neck end, slip-on and threaded. Orifice Class #600 and flanges above that Class, can be obtained in only weld neck type end.
