Opening Flange
Opening Flanges Manufacturer
JK ENGINEERING WORKS is reckoned amongst the prominent Industrial Opening Flanges Exporter in Mumbai. ASME B16.36 flanges are orifice flange 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. Opening flange of ASME B16.36 can be obtained from Class #300 – Class #2500. Opening Class #300 flanges are procurable in types such as weld neck end, slip-on and threaded.
Opening Class #600 and flanges above that Class, can be obtained in only weld neck type end. Opening flange of ASME B16.36 are produced in various grades and sizes. Opening flange 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.
When the inspection of ASME B16.36 Opening flange is being carried out, it is crucial to check for the length of the hub, bolt circle and bolt hole diameter, straightness and alignment of the bolt hole, thickness of weld end, outer and inner diameter of body and tap holes dimensions. Opening flanges of ASME B16.36 are available in weld neck, threaded and socket weld, they are obtainable in different dimensions and they are also available in all ASTM forged grades (182, A350, A105 and A694). An Opening flange union is 2 orifice flanges joined together.
Opening flange are basically the same as slip on flanges or weld neck flanges, the differences being that stainless steel Opening flanges of ASME B16.36 have extra machining and another difference is that in the flange ring, orifice flanges have radial, tapped holes. This serves as the purpose of meter connections and so that additional bolts can serve as jack screws to allow for the separation of flanges, at the time of replacement or inspection of the orifice plate. We are the best Opening Flanges Wholesaler in Mumbai & Give you best Industrial Opening Flanges Prices in Mumbai.
ANSI/ASME B16.36 Opening flange 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 Opening flanges includes nuts, Opening 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, Opening flanges of ASME B16.36 are used. Generally, sopening flanges are available in RTJ (Ring Type Joint) facings or as Raised Faces. The most used Opening 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. Opening 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.
