What is a Pipe Reducer?

First, let’s keep it simple: A pipe reducer is a pipe fitting that connects a larger pipe to a smaller pipe. Thus, it reduces the size of the pipe in the pipe system, from one size to another. Pipe reducers may frequently be used to connect pipes of different sizes. There are a variety of reasons why this might be done, and there are a variety of materials that could be flowing through the pipe, which is why there are different types of pipe reducers.

Like other pipe fittings, it can be very complicated to find the right pipe reducer. The fit can be complicated, and materials will matter. But once you find the right pipe reducer, the installation should be fairly simple and fast.

When Would You Use a Pipe Reducer?

Reducers can be used simply to adapt pipes of other sizes, but there are also more complicated uses for them. They may need to be used when the flow has to be limited or expanded in a piping system, such as if the hydraulic nature of the piping system demands it. If you’re using a pipe reducer, you need to consider the consequences for the pipe system as a whole, because there will be changes in both flow and pressure.
Once you know that you need to use a pipe reducer, you need to make the decision between concentric and eccentric reducers. Most people are going to need to use a concentric pipe reducer, but there are some important reasons why an eccentric pipe reducer might be preferred.

Concentric vs Eccentric Reducer: What’s the Difference?

While this may seem complicated, it’s actually quite simple. Concentric reducers reduce the pipe in the center. So, if you’re looking at the reducer head-on, you can see the smaller section is formed in the direct center of the larger side. Eccentric reducers reduce the pipe to the side. So, if you’re looking at the reducer head-on, you can see the smaller section is against one side of the larger side.

This may seem like a very simple change, but it does matter.

The cone-shaped concentric pipe reducer means the pipes have matched center lines, and the eccentric reducer has mismatched center lines. Both of these have a consequence regarding flow. Most reducers are going to be concentric. Eccentric reducers are used when the pipes have to maintain the same top or bottom level. Eccentric reducers are frequently used to avoid trapping air within the system, so they are often used when both air and liquids may be flowing together.
Most people are going to need a cone-shaped concentric pipe reducer because they aren’t going to need one side of the reducer to remain flat. But in many applications, either can be used, as long as the bottom of the eccentric reducer is placed correctly. The major concern about eccentric reducers is that they can collect liquids or gasses in one area if they are not properly aligned. When used vertically, there is essentially no difference between a concentric or eccentric pipe reducer.

What About Concentric and Eccentric Expanders?

It should be noted that while they are called reducers, reducers by their very nature are also expanders. They are simply used in the opposite direction as expanders. Thus, expanders can also be both concentric and eccentric, and the consequences of using one or the other to expand rather than reduce are the same. Either way, they are being used when a pipe of one size has to transition to a pipe of another size.

How Are Reducers Installed?

How a reducer is installed depends on the material that the reducer and the pipes are made from. If the reducer and pipes are made from metal, they can be butt-welded together. If the reducers are made of PVC, they will likely be fitted and glued. There are reducers that may have push-to-fit or crimp installations as well. It depends on how the reducer was made, the material, and the goals for the reducer.
To install the reducer, the reducer will be fitted on both pipes and connected in the appropriate way. But care must be taken with eccentric reducers to ensure that the bottom of the eccentric reducer is properly lined up. In piping liquids horizontally, eccentric reducers need the flat side up, because otherwise, gasses can collect. But in piping vapors horizontally, eccentric reducers need the flat side down, because they need to avoid collecting liquids.

The more the pipe is reduced, the more concerns there may be related to flow. If the pipe is only being reduced a little, then there shouldn’t be any complications.

What is a Pipe Reducer?

A pipe reducer is a pipe fitting that connects a larger pipe to a smaller pipe. Thus, it reduces the size of the pipe in the pipe system, from one size to another.

Advantages of use of Buttweld Fittings

A piping system using buttweld fittings has many inherent advantages over other forms.
1. Welding a fitting to the pipe means it is permanently leakproof
2. The continuous metal structure formed between pipe and fitting adds strength to the system
3. Smooth inner surface and gradual directional changes reduce pressure losses and turbulence and minimize the action of corrosion and erosion
4. A welded system utilizes a minimum of space
