The ASTM A403 Reducer is made up of an austenitic stainless steel that is forged and rolled. So it can withstand high pressure and temperature in the exhaust functionality. There are different types of reducers. The Stainless Steel Eccentric Pipe Reducer has an asymmetric shape so that it aligns the larger and smaller pipes to one side of the pipe line; not in the center of axis. There are different classes and standards of this product. The ASME B16.9 Buttweld Reducer is buttweld, which means it is very strong at the connection. It also covers nominal sizes from NPS ½ to NPS 48. These are used in small to medium size pipes. Depending on the need of the application, we produce eccentric reducers as well. The eccentric reducers have their diameters aligned to the center. So the Ss Concentric Reducer doesn’t change the axis of flow. This is important in high pressure and high speed fluid flow systems not to interrupt the direction of flow and to keep less friction on the walls. We produce different SS Buttweld Pipe Reducer Dimensions according to our customer needs. Any customization could be arranged upon contacting us.
