Stainless Steel Orifice Flanges, Size: Above 30 inch

Product Details

Orifice Flanges are used with orifice meters for the purpose of measuring the flow rate of either liquids or gases in the respective pipeline. Orifice flanges generally come with either raised faces or RTJ (Ring Type Joint) facings. They are, for all intensive purposes, the same as weld neck and slip-on flanges with extra machining. They have modifications of radial tapped holes in the flange ring for meter connections and orifice plate carriers for the reason of fitting meter connections. The additional bolts act as a jack to allow the separation of the two flanges to change the orifice plate or for other inspection services. Skyland Metal And AlloysInc. offers these flanges in stainless steel material. For carbon steel, We not only stock certain sizes of this flange, but has been a reputable source for them for over thirty years. We usually supply the plate, pressure connection holes, and jack screws with the orifice flange unit (which is usually two flanges mated together and ready for use) Please contact our sales department with additional questions on orifice flanges.Key Features:Available with raised face or RTJ faceUsed for flow/rate metering of piping systemsSFF can supply the plate, pressure connection holes, and jack screws with the orifice flange uniOrifice Flanges are used with orifice meters for the purpose of measuring the flow rate of either liquids or gases in the respective pipeline. Pairs of pressure "Tappings", mostly on 2 sides, directly opposite each other, are machined into the orifice flange. This makes separate orifice carriers or tappings in the pipe wall unnecessary.Orifice Flanges generally come with either Raised Faces or RTJ (Ring Type Joint) facings. They are, for all intensive purposes, the same as weld neck and slip on flanges with extra machining.The image on the right shows a set Orifice Flanges, where a Orifice Plate is mounted and a jack screw is machined. This jack screw is used to facilitate separating the flanges for inspection or replacement of the Orifice Plate and gaskets.The range of orifice flanges covers all standard sizes and ranges, and all common flange materials. Flanges are available in Welding Neck, Slip On, and Threaded form, and are typically supplied with two 1/2" NPT tappings in each flange.ASME B16.36 covers Dimensions and dimensional tolerances from orifice flanges (similar to those covered in ASME B16.5) that have orifice pressure differential connections. Coverage is limited to the following flanges:WELDING NECK CLASSES 300, 400, 600, 900, 1500, 2500SLIP ON CLASS 300THREADED CLASS 300
