What Does a Concentric Reducer Do?

A concentric reducer is a common fitting used in plumbing, HVAC and other piping systems. This device is designed to reduce the size of a pipe from its larger diameter to its smaller diameter while keeping the two ends of the pipe in alignment. It can be used with pipes that have dissimilar diameters or those that are tapered, such as compression fittings.

Applications for Concentric Reducers

Concentric reducers are used in a variety of domestic, commercial and industrial applications. In plumbing systems, they are often used to connect two different sizes of plastic piping, such as when transitioning from a larger pipe size for supplying water to a smaller size for draining away wastewater.

In HVAC systems, concentric reducers can be used for transitioning from a larger pipe size carrying heated air to a smaller one carrying cold air. In industrial applications, concentric reducers are frequently used for connecting pipes of varying diameters that transport various substances such as chemicals or lubricants.

Common Materials for Concentric Reducers

Concentric reducers are made using various materials, including malleable iron, stainless steel, carbon steel and copper. The selection of material depends on the application and environment in which the device is to be used. Also, concentric reducers are available with threaded or slip-on connections to accommodate different types of piping systems. Let’s look at each of these materials in turn.

Malleable iron is a common choice for domestic and commercial plumbing applications, as it is strong and corrosion-resistant. It may not be suitable for use in industrial settings due to its low melting point.

Stainless steel is the material of choice for many industrial applications due to its high strength, durability, and corrosion resistance. However, its cost can be a deterrent. Despite this, stainless steel concentric reducer fittings are the most common type used in industrial applications.

Next, carbon steel reducers are also frequently used in industrial settings, due to their low cost and good corrosion resistance. Yet, they are not as durable or strong as stainless steel reducers.

Lastly, copper concentric reducers are commonly found in domestic plumbing systems due to their corrosion resistance, low cost, and good heat transfer abilities. However, copper fittings are not as suitable for industrial applications due to their lower strength and durability.

Benefits of Concentric Reducers

Using a concentric reducer provides several benefits over other types of fittings, such as improved flow rate and reduced pressure loss. By maintaining the same centre line for both ends of the pipe, these devices help reduce turbulence in the system. In turn, this reduces friction and increases efficiency since there is less resistance from the fluid.

Concentric reducers also provide a tighter and more secure connection which prevents the escape of any fluid. This is especially important in volatile applications such as those involving chemicals or other hazardous materials. What’s more, these fittings can be used to increase or decrease pipe size based on need, thus providing flexibility in the design of piping systems.

Summary

All in all, a concentric reducer is an essential fitting for any piping system. It helps maintain the right diameter of pipes and ensures that they remain aligned at both ends. This device can be made of various materials such as malleable iron, stainless steel, carbon steel or copper depending on the application.
