A reducer is a form or pipe fitting (accessory) that is used in process piping for changing the size of a pipe from a large bore to small bore pipe. Reducers are typically used to modification in the size of the pipe in order to meet the flow specifications in the processing system, or connect to existing large or small pipe bores according to the requirements. The length that the reducer has is nearly equivalent to the mean of the large or smaller diameter pipe.
There are two kinds of reducers available in industries . They are concentric as well as eccentric reductionrs. Eccentric reducers help to ensure that the flow of services remains at on the same level at the top of the pipe or the bottom level within the pipeline. Pipe reducers are the type of pipe fitting that allows the joining of two pipes of different dimensions. The pipe reducers are made in a range of materials and design variations to meet the needs of the users. They are also can be found in various sizes. It is used in conjunction with a piping TEE fittings, and is also known generally reduction TEES. This is to cut branch connections from the header pipe generally 90 degrees. It could be the exact size of the pipe that reduce TEE, or different, based on the requirements of the user. Reducer is more economical in comparison to cutting down TEE. It is also easy to manufacture, lighter in weight. Reducers that are time-explicit are made on the site of the manufacturer. Reducers can also be used as an expander when needed by turning the face of its. It is similar to Olets (weldolet or sockolet latrolet, thredolets , etc.)
How do you select a the right reducer
There are many factors to consider when selecting the best pipe reducer. Some of the most crucial are described below.
Select the DN (nominal diameter) and then schedule the 1st pipe end to be like (100NB 25NB).
Select the DN (nominal diameter) and plan for the 2nd pipe’s ending (small diameter pipe bore)
Distance between one pipe end and another pipe’s end
Select the standard sizes that are used for the reduced ASME B16.9 (Butt Weld Fittings, MSS SP-43 ASME B36.19 MSS SP-43)
Select the design standard that you want for the reducer.
Reducer fitting process (Seamless or ERW also known as electric Resistance Welding).
Choose one of the (MOC) components of your fittings, such as mild steel (MS) or stainless steel (SS), Corbon Steel, Monal, etc.
Choose Class, Pressure rating or schedule, in accordance with the piping design you have chosen.
What kind of reducer (eccentric or con-centric) you should choose according to your requirements?
What type of end connection needed? Bevel end (PE) Bevel end Flange end.
The types of welds that are required Socket welds or Butt welds.
Resistance to corrosion
Durability
Note: For the an overall thumb rule of safety and to obtain the appropriate output for the design system The reducer Wall Thickness must not exceed 87.5 percent from Nominal Wall Thickness.
What are the different types of reducers? What is a kind of reducer?
There are two major varieties of it, described below.

Concentric Reducer
Concentric Reducers are used to join the two tube or pipe sides to their respective axis. The pipe ends connected to each other may be the same, or differ in diameter and also, based on the needs of the user.
The most important thing is that they allow for a conical transition in-line between pipes that are pressurized and have unmatched diameters. However, the drawback of this kind is that when you place concentric reducers horizontally there is always the possibility of the formation of pockets of air or vapor in the upper portion of it. The pipes do not know what the exterior that the reduction pipe is like. The pipe’s flow can be affected because of the conical inside diameter transition, which is relocated axially and then externally changed to make it more cost-effective reducer fittings. Concentric fittings connect pipes of different sizes and also eccentric, but share common centersline. This means that they are referred to as the Concentric reducer, or reduction of the size of pipes is accomplished through the reduction of size of fittings at a consistent rate over a specific length while maintaining the symmetry of the fitting. It is a form of fitting for pipes that connects the various pipes with different diameters, which join together on the same direction. Concentric reducers are made using the smaller and larger diameters on opposite sides and connected by a cone-shaped transition section. T are available both in seamless and welded. Reducers that concentrate reduce the diameter of the pipe at the center. It is recommended to discharge it or vertically utilized for maximum benefits.
How do I measure seamless concentric reducers?
There are a few important measurements to make to fabricate or record to use in the future fabrication. Take measurements of the inner diameter (OD) and inner diameter (ID) and height (H) as well as overall dimension (T1 T2).
Concentric Reducers’ Benefits and applications of concentric reducers
Concentric reducers can be used for a variety of purposes. Some examples are like this:
Reducers with a concentrated design will smoothly transition between the pipe and the pump.
Concentric reducers aid in the transportation of abrasive or slurry liquids.
They can be useful in situations in which cavitation occurs.
If transporting between flanges or pipes with different ratings and the need for wear protection is essential concentric reducers work well.
Concentric reducers are employed in the discharge of the pump.
Eccentric Reducer
A pipe fitting with an eccentric design is made with the smaller outlet running off the center towards the bigger end that allows it to be aligned with just part of the outlet.
The reducer should be placed in a straight line to prevent blocking air from the suction pump. The eccentric reducers for pipes allow the easy joining of different sizes of pipes. Eccentric reducers narrow the pipe’s length to its side, but it is recommended to use it placed in suction or horizontally in order to maximize the benefits. Eccentric reducers, reduction of the size of the pipe is achieved through the reduction of in diameter the pipe at a steady amount over a certain length while maintaining the other end of the pipe in a horizontal position.
Benefits of eccentric reducers and the use for eccentric reducers
Keep big pipes and small pipes in a single.
The reduction of noise and vibrations while at the same time.
Requires less installation space.
Absorbs the sound of pipe walls and fluid generated noise.
There is less turbulence and less material Entrapment.
Eccentric reducers can be used with the flat side facing up in pump suction to prevent cavitation.
Why does reducer get employed in pipelines?
The most important function of reducers in pipe lines is to regulate the flow and the tension of the system to provide the intended operation. They also connect two diameters of pipes to achieve the desired flow to the system. Connect large bore pipes and small bore pipes.
What is the pipe reducer?
Pipe reducers are used to join two pipe lines using butt welding socket weld, Flanged joint.
What exactly is the difference between increaser and decreaser?
There are two kinds of reducers that are utilized to connect two identical diameter pipes. They are called Reducer and Increaser. Increasers are used in similarly to reducer for pipe line, however when connecting the face of the increaser is reversed compared to the reducer. The increaser is utilized to increase the diameter of the pipe the downstream within the line pipe system unlike reducer, the same thing are reversed. Everything is identical between the two.
