Concentric & Eccentric Reducers
Concentric Reducers
Concentric reducers maintain a common centreline between the larger and smaller pipe ends, providing a symmetrical reduction in pipe diameter. They are the standard choice for vertical piping runs and applications where maintaining the pipe centreline is important. Shree Raj Steels supplies concentric reducers from 1/2" to 60" in seamless and welded constructions across all standard material grades.
