Difference Between Eccentric and Concentric Reducers

Pipe reducers are vital components in your piping systems. These fittings help you connect ducts and pipes of various sizes. You can use them when there are variations in single or multiple diameters. The primary purpose of the pipe reducers is to reduce the pipe’s size. In fact, choosing the most appropriate pipe reducers is challenging. 

How to install reducers

A reducer installation technique depends on the materials used for the pipes and the reducer. If you use metal pipes and reducers, you can butt-weld them together. In the case of PVC reducers, you may apply glue. Some reducers allow crimp or push-to-fit installations. You have to fit the reducer on both pipes and ensure they are connected appropriately. However, you must be careful about eccentric reducers to keep their bottoms lined up properly.

Applications of concentric reducers

The main reason for using concentric reducers is for joining tube or pipe sections on a particular axis. They are cone-shaped concentric reducers used in projects in case there is a variation in diameter between your pipes. For instance, if there is a transition of 1″ pipe into your 3/4″ pipe, you may not find a proper leveling of the pipe’s top and bottom. So, you can use the concentric pipe reducer that comes with a common centerline. If the centerline is balanced, it leads to eccentricity.

Uses of eccentric reducers

Eccentric reducers are pipe fittings for systems, which involve using pipes of various diameters. You can reversely use the fitting as the eccentric exponent or increase. While the concentric reducer looks like a cone, eccentric reducers come with an edge parallel to the flat side of the pipe.

The parallel edge leads the pipes that have balanced centerlines. Asymmetrical eccentric reducers generate asymmetrical flow. The flow is comparatively faster, and it leads to a higher pressure.

Liquid reducers with horizontal designs are eccentric. They will prevent the accumulation of air bubbles in your piping system. The eccentric reducer’s flat side is at the base in your pipe rack.

The reducer can be used at the pump’s suction side to prevent air buildups in your pipe. The air accumulation in the concentric reducer leads to bigger bubbles. 

Concentric versus eccentric reducers: Know more about their differences

Concentric reducers improve fluid flow and minimize the diameter. They do not affect the fluid flow. So, you can use them for pipelines that allow vertical flow of the liquid. On the contrary, eccentric reducers help with the discharge of the liquid because one of their sides is flat. If the pipelines are positioned horizontally, you can use eccentric reducers.

You can invest in concentric reducers to move abrasive fluids and slurries. Moreover, these reducers are useful in projects that involve the risk of corrosion. On the contrary, eccentric reducers are advantageous because they do not need considerable space for a setup.

So, the brief comparison will help you make efficient pipe reducer choices. Compare the features and other aspects before buying pipe reducers.
