Stainless Steel Orifice Flanges

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. Orifice flanges of ASME B16.36 are produced in various grades and sizes. Orifice flanges of ASME B16.36 are obtainable in a variety of standard materials and special materials such as A182 F316 Stainless Steel, A182 F22 2¼% Cr 1% Mo, A105 Carbon Steel, A182 F304 Stainless Steel, A350 LF2 Low Temp Carbon Steel and A182 F11 1% Cr ½% Mo.

ANSI/ASME B16.36 orifice flanges are used together with orifice meters and in this way it becomes possible to measure the flow rates of gas, oil and other liquids that have been transported in a pipeline. The conventional assembly of orifice flanges includes nuts, orifice plate, bolts, plugs, gaskets, a couple of flanges and jacking screws. Because of the jacking screws, easy removal of the primary flow element is accomplished. When there is a need for the installation of a flow nozzle or an orifice plate, instead of using standard pipe flanges, orifice flanges of ASME B16.36 are used. Generally, orifice flanges are available in RTJ (Ring Type Joint) facings or as Raised Faces. The most used orifice flanges of ASME B16.36 are weld neck flanges and the most popularly used among these are Threaded Class 300, Slip On Class 300 and Welding Neck Classes 900, 300, 2500, 600, 400 and 1500. Orifice flanges of ASME B16.36 can be constructed from a variety of materials such as carbon steel, alloy, stainless steel and any other suitable material.

We keep huge preminum quality product stock of Class 150 Orifice Flat Faced Flange, Raised Face Orifice Flange, Orifice Forged Flange, Orifice Plate Flange, Class 300, 600, 900, 1500 Orifice Flange.

These flanges are used in pairs & between them; there is a disk with a calibrated hole to measure the flow of liquid at a certain point in a pipe. They have two radial holes situated at 180deg for the insertion of pressure gauges, which are usually stopped by threaded plugs.
