Introduction
The reducer is a commonly used pipe fitting in the pipeline system, mainly used to connect two steel pipes of different diameters. There are two types of reducers: concentric reducers and eccentric reducers. This article mainly introduces the uses of these two types of reducers and their respective advantages and disadvantages.
What is a concentric reducer?
A concentric reducer is a reducer with a centerline on a straight line. It is mainly used to connect steel pipes or pipe fittings of different diameters. Concentric reducers are often used in vertical pipeline systems, which can make the objects in the pipeline flow more smoothly. There is no need to worry about backlogs and corrosion of the concentric reducer.
Advantages of concentric reducers
- It can ensure that the objects in the pipeline can flow smoothly.
- It is more suitable for connection with pumps to prevent gas erosion.
- Because the centerline is on a straight line, it can effectively correspond to the pipeline.
Common applications of concentric reducers
- Vertical pipeline system
- Pipeline area adjacent to the pump
- Area where objects flow smoothly in the pipeline.
What is an eccentric reducer?
The centerline of the eccentric reducer is offset and one side is flat. This type of reducer is mostly used in flat pipes. It is selected according to whether the object in the pipe is liquid or gas, and one side of the reducer is facing up or down.
Advantages of eccentric reducers
Prevent cavitation: often connected to pumps.
One side is flat: it can ensure that the liquid will not be retained at the end of the rough mouth when installed horizontally.
Common applications of eccentric reducers
- Horizontal pipeline system
- Pipeline area adjacent to the pump
- Area where objects flow smoothly in the pipeline.
Concentric and eccentric reducers: What is the difference?
There are some subtle differences in production process and use, the main difference is that one center line is in a straight line and the other is not in a straight line.
Design differences
Concentric reducer: The center lines are in a straight line.
Eccentric reducer: The center lines are not in a straight line.
Application differences
Concentric reducer: Mainly used in vertical pipeline systems.
Eccentric reducer: Mainly used in horizontal pipeline systems.
Cost and size considerations
Concentric reducer: The production process is relatively simple, so the price will be relatively cheaper.
Eccentric reducer: The production process is slightly more complicated than that of concentric reducer, and the price is also more expensive. However, the choice must be made according to the use environment.
When to use concentric reducer and eccentric reducer
Use concentric reducer: Commonly used in vertical system pipelines, it can align pipelines and pipeline special flows well. And it is mostly used at the discharge end of the pump pipe.
Use eccentric reducer: It is mostly used in horizontal pipeline systems. You can choose the plane upward or downward according to the pipeline object, so that the liquid or gas inside can be kept horizontal and prevent the formation of cavitation or liquid accumulation. And it is mostly used at the suction end of pump farmers and herdsmen.
Summary
Concentric and eccentric reducers both play an indispensable role in the pipeline system, but some differences between the two still have a certain impact on their selection. The reducer selected is conducive to the connectivity and service life of the pipeline. After reading the above, I believe you have a certain understanding of how to choose two reducers.
