Eccentric reducer
An eccentric reducer changes line size with the two end centerlines offset, preserving one side of the transition along a selected alignment. This distinguishes it from a concentric reducer, whose ends share a common centerline. Eccentric geometry is considered where maintaining one elevation or controlling the transition layout matters. Flat-side orientation depends on the fluid, pipe slope, potential gas or liquid accumulation, and connected equipment arrangement; selection and installation direction must therefore follow the system design rather than a universal rule.
Application and duty
Changing line size where one-side elevation or transition layout must be maintained; orientation must be determined for the actual service.
