Arcellor Controls is leading Stainless Steel Reducing Flange Manufacturers in India, designed for when there is a change in the pipe size. The predominate flange (dimensions) matching the larger pipe size (NPT) but having a smaller bore matching the smaller pipe size (NPT). These ASME B16.47 Reducing flanges normally come in blind, slip-on, threaded and weld neck flanges.
ASME B16.5 Reducing Flanges are available in all pressure classes and provide a good alternative to connecting two different sizes of pipe. This type of reducing flange should not be used if an abrupt transition would create unwanted turbulence, such as at a pump.Reducing Flanges are mostly used where application need fittings to different sizes. A reducing flange b16.5 consists of a flange with one specified diameter having a bore of a different and smaller, diameter.
