An IBR Reducer is the component in a pipeline that reduces the pipe size from a larger 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 IBR Reducer: IBR Concentric Reducer and IBR Eccentric Reducers. An IBR Reducer can be used either as a nozzle or as diffuser depending on the Mach number of the flow. Nexus Steel manufactures IBR Reducer in Seamless Construction up to 24”NB and in welded Construction up to 48”NB.
