About Pipe Fitting Reducer

Reducers in Process Piping
A reducer is a kind of pipe fitting used in process piping that reduces the pipe size from a bigger bore to a smaller bore (inner diameter).
A reducer allows for a modify in pipe size to reach the hydraulic flow requirements of the system or to adapt to existing piping of a different size. The length of the reduction is generally equal to the average of the bigger and smaller pipe diameters.
There are 2 main types of reducer:

• Concentric reducers
• Eccentric reducers

Reducers are ordinarily concentric but eccentric reducers are utilized when required to maintain the same top-or bottom-of-pipe level.
Concentric Reducer
In Concentric Reducer the deduction of the pipe size is accomplished by reducing the diameter of the fitting at a constant rate over a specified length, maintaining symmetry around the fitting. Concentric Reducers are utilized to join pipe or tube sections of different diameters on the same axis. They provide an in-line conical transition between pressurized pipes of differing diameters. Thus, concentric reducers connect pipes of unequal size but have a common centerline. The same fitting can be used in reverse as a concentric expander.
Eccentric Reducer
In an Eccentric Reducer, the deduction of the pipe size is accomplished by reducing the diameter of the fitting at a constant rate over a specific length, maintaining 1 side of the fitting horizontally. Eccentric pipe reducer fittings are manufactured with the smaller outlet off center to the bigger end, which allows it to align with just one side of the inlet. The same fitting may be utilized in reverse as an eccentric expander.
Uses of Concentric and Eccentric Reducers

• In horizontal liquid piping, eccentric reducers must be installed with a flat side up so that it can prevent trapping air in the piping system. As an exception, the same is flat side down in the pipe rack where the same Bottom of Pipe (BOP) has to be maintained. Another exception is with control valves. An eccentric reducer with a flat side down can give a more constant flow through the control valve rather than an eccentric reducer or concentric reducer with a flat side up, which can give you more flow disruption and can cause problems with your control valve.
• In horizontal gas/vapor/steam piping, eccentric reducers have to be installed with a flat side down which allows condensed water or fluid to drain at very low points.
• Eccentric reducers are mainly utilized at the suction side of pumps to ensure air doesn’t accumulate in the pipe. The gradual accumulation of air in a concentric reducer could result in a big bubble that could eventually cause the pump to stall or cause cavitation when drawn into the pump.
• Reducers in vertical lines are basically concentric unless the layout dictates otherwise.
