We are a Duplex Stainless Steel A815 UNS S31803 Reducer Manufacturer, A815 WP S31803 Duplex Steel Reducer, ASTM A815 WPS UNS S 32205 Stainless Steel Reducer Pipe Fitting Manufacturer, ASTM A815 Duplex Steel UNS S31803 Reducer ANSI B16.9 Duplex UNS S32205 Reducer, a reducer is a kind of pipe fitting used in pipeline that reduces the pipe size from a larger bore to a smaller bore (inner diameter). The length of the reducer is usually equal to the average of the larger and smaller pipe diameters. There are two main types of reducers: Concentric reducers and eccentric reducers.
