Aakash Seel is highly acclaimed supplier, manufacturer, and exporter of Stainless Steel Reducing Flanges that are custom built to suits various industrial applications. We are involved in expanding our presence worldwide. We engaged in supplying Reducing Flange in Monel, Inconel, Hastelloy, Alloy Steel or Carbon Steel , it possess the ability to join pipes of varied sizes together with great ease. ANSI B16.5 Reducing flanges are suitable for high-pressure systems like condensers and boilers as well can endure extreme pressure.
Reducing Flanges are a type of fittings that are used to change the size of a pipe in a system. Although the Reducing flange fittings are well known to be suitable for changing the line size, these threaded reducing flanges ideally should not be used if the application frequently shows signs of an abrupt transition. A Carbon steel reducing flange consists of a flange with one specified diameter that has a bore of a different or smaller, diameter. Applications for the stainless steel reducing flange involve being used in industries such as off-shore and shipbuilding, oil field, power plants, water system, and in industrial vessels.ASME B16.5 Reducer Flanges are produced by a Reducing Flanges Manufacturer between the size range of NPS 1/2 through NPS 24 Metric/Inch which covers several points such as dimensions, marking, testing, materials, tolerances, pressure-temperature ratings, and methods of designating openings for pipe flanges like the SS Reducing flange and flanged fittings. Besides these points, the ASME B16.5 standard also includes requirements and recommendations regarding the flange gaskets, flange bolting,as well as flange joints.

ANSI B16.5 / ASME B16.47 SS Reducing Flange Used in
Utmost care is taken towards the packing of the Reducing Flanges so as to ensure that the resultant Products reach in the same condition as desired by our customers from varied industries. We focus on every procedure to assure quality, the package we usually prefer is environmental poly bags, and then in free fumigation wooden cases or plate. Also can accept a customized package of Stainless Steel Flange such as OEM by negotiation. We offer just about everything to meet your 304/316 SS Flanges pack requirements. A Lot of emphases is placed on the packing and packaging. The SS ANSI B16.5 / ASME B16.47 Reducing Threaded Flange is packed in wooden corrugated boxes foiled in plastic wraps and bubble wraps. Below are Application Industries where we supply and export.
