Plumbers employ a multitude of pipe fittings to control and direct the flow of fluids in plumbing systems. Pipe reducers are a common fitting used to connect two pipes of different diameters to maintain flow rate and pressure between them. Plumbers should be familiar with two types of pipe reducers: concentric and eccentric reducers. Discover the purpose of each reducer, their differences, and which one you need for each job.
Concentric Reducers
A concentric reducer is a type of pipe fitting used to join two sections of piping that have different diameters but share a common central axis. This alignment ensures a uniform flow from one pipe to another, making it ideal for vertical piping systems. Concentric reducers are the more popular reducer type to keep fluids at a consistent flow between a larger and a smaller diameter pipe.
Eccentric Reducers
Eccentric reducers are designed to join pipes of different diameters, but unlike concentric reducers, their central axes do not align. This design allows eccentric reducers to maintain a flat top or bottom to maintain the same top or bottom level.
The flat alignment prevents the accumulation of air bubbles, which can cause flow disruptions and reduce system efficiency. Eccentric reducers can also serve as expanders, enabling the transition from a smaller pipe size to a larger one to accommodate increased flow requirements.
Which One Do You Need?
When deciding between concentric and eccentric reducers, consider the specific requirements of your plumbing project. If your system involves vertical piping and you need to maintain a constant rate, concentric reducers may be the best fit. On the other hand, if your focus is on preventing air accumulation in horizontal systems, an eccentric reducer is likely the better choice.
Concentric reducers are designed to maintain a consistent centerline, making them ideal for applications where alignment is crucial. In contrast, eccentric reducers help manage fluid flow by minimizing turbulence, allowing fluid drainage at low points when installed flat side down.
Selecting the right reducer is essential for the optimal functioning of your plumbing system. Make informed decisions to ensure seamless flow and efficient operation.
