About Concentric Reducer
ASTM A815 S31803 Duplex Steel Concentric Reducer is a type of pipe fitting used in pipelines to reduce the pipe size from a larger bore to a smaller bore (inside 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.ASTM A815 S31803 Duplex Steel SMLS مخفف متحدة المركز
