1. ASTM A815 S31803 Duplex Steel Concentric 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 reduction is usually equal to the average of the larger and smaller pipe diameters. There are two main types of reducer: Concentric reducers,and eccentric reducer.
