ASME B16.9 Reducer And Buttweld Concentric/ Eccentric Reducer Fittings (2023)

Check Where Buttweld Reducers Used In Pipeline, ISO Approved Stainless Steel Concentric Reducer Manufacturer In India


ASME B16.9 Reducer And Buttweld Concentric/ Eccentric Reducer Fittings (1)

Reducers are used to connect a larger size pipe to a smaller size pipe. This is usually done to meet hydraulic flow requirements. ASME B16.9 Reducer is a grade that is light in weight and provides resistance to corrosion. Stainless Steel Concentric Reducer manufacturer In India manufactures these reducers in the size range of 8 inches to 36 inches. Buttweld Reducer is available in seamless and welded form.ANSI B16.9 Ecc And Con Reducer are ideally used when there is a shift in diameter.

JIS B2312 Reducer is produced in a way that the outlet and inlet ends are aligned on a common centerline. Welded And Seamless Reducer offer resistance to stress-related corrosion cracking as well as pitting. ANSI B16.9 Reducer also offers good tensile strength and creep resistance, along with hardness. Physical dimensions of 8 Inch To 6 Inch Concentric Reducer have a cone shape that decreases gradually around the pipe. The reducer displays cavitation when there is an accumulation of air.

3 Inch To 2 Inch Eccentric Reducer is used in industries such as natural gas, power generation, chemical, paper making, petroleum, and heating. Eccentric Reducer reduces the pipes from the side. WhereasCopper Ecc Reducer is available in a different class and can be bifurcated in 30/70 and 90/10 alloy. SS Eccentric/ Concentric Pipe Reducer have their own pros and cons. However, one of the major concerns of eccentric EN 10253-4 Type A Reducer is that they collect the gases and liquids in one area in case they are not aligned properly.

What Is Concentric And Eccentric Reducer?


Eccentric Reducer : Carbon Steel Eccentric Reducer however does not cover low-pressure corrosion resistance.
Concentric Reducer : Aluminum Concentric Reducer is used in a wide variety of environments without compromising or losing on their mechanical properties.


Where Concentric Reducer Used In Pipeline


Concentric Reducer reduces it from the center this creates a major difference in the shape and dimensions of the reducers. CS Con Reducer is less prone to cracking due to thermal stress and added durability.

FAQs

What is the difference between eccentric reducer and concentric reducer? ›

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.

What is an eccentric reducer used for? ›

Eccentric reducers are used at the suction side of pumps to ensure air does not accumulate in the pipe. The gradual accumulation of air in a concentric reducer could result in a large bubble that could eventually cause the pump to stall or cause cavitation when drawn into the pump.

When would you use a concentric reducer? ›

The concentric reducer is cone-shaped, and is used when there is a shift in diameter between pipes. For example, when a 1" pipe transitions into a 3/4" pipe and the top or bottom of the pipe doesn't need to remain level. This pipe reducer may be used when there is a single diameter change or multiple diameter changes.

How many types of reducers are there? ›

There are 2 types of standard reducers available: concentric and eccentric reducers. The concentric one, which resembles a cone, is used to join pipe sections on the same axis. The eccentric type has an edge which is parallel to that of the connecting pipe, which allows it to align with one side of the inlet.

Where do we use eccentric and concentric reducers? ›

Concentric reducers are used where the pipework is vertically installed and at the discharge side of pumps. Eccentric reducers are more often used when the pipework lays on a pipe rack. Because of the flat side, aligning and securely mounting the pipes to the rack is easier.

How should an eccentric reducer be installed? ›

Eccentric Reducers Installation

When the source of supply is above the pump, then the eccentric reducers must be placed with the flat side down. When the source of supply is below the pump, then the eccentric reducers must be placed with the flat side up.

What is the difference between concentric and eccentric? ›

There are 2 types of isotonic contractions: concentric and eccentric. In a concentric contraction, the muscle tension rises to meet the resistance then remains stable as the muscle shortens. During eccentric contraction, the muscle lengthens as the resistance becomes greater than the force the muscle is producing.

How do you find the center of eccentric reducer? ›

This is the Way to Find the Center of a Eccentric Reducer - YouTube

Why concentric reducer is used in pump discharge? ›

Many times the discharge size of a pump is specified small, to allow the use of lower cost valves at the discharge and then expanded up by means of eccentric reducers. The use of concentric reducers should be considered since they are much more effective at converting the velocity pressure to static pressure.

On which side of a pump do you typically install an eccentric reducer? ›

USE ECCENTRIC REDUCERS ON THE SUCTION SIDE

Consider using eccentric reducers on the suction side of the pump when a pipe size transition is required. Install the flat side of the reducer on the top when fluid is coming from below the pump.

What does eccentric mean for pipe? ›

An eccentric tube is one that has the center of the tube formed by the OD which is at a different point from the center formed by the ID, so the 2 dimensions are not concentric.

How do you determine reducer length? ›

The length of the reduction is usually equal to the average of the larger and smaller pipe diameters.

Which type of pipe fitting is used for reducing diameter of pipe? ›

Coupling, Adapter, Bushing and Union Fittings

A coupling can be a reducer, or reducing coupling, meaning they reduce flow by joining a larger pipe to a smaller size. Adapters are used when connecting two pipes of different types.

What is offset in eccentric reducer? ›

2, in eccentric reducer there is an offset in between the center lines of the bigger end and the centerline of smaller end. This offset or eccentricity will maintain a flat side either on top or on the bottom side.

How do you calculate eccentric reducer weight? ›

Can you use a reducer in reverse? ›

Yes, they can be used in either direction.

What is a reducer fitting? ›

A reducer fitting is typically used in pump station pipe work to reduce the size of the suction pipe to match the size of the pump suction end flange. Reducer fittings used in pump inlet pipe work are divided into two types—concentric and eccentric reducers.

Which pipe fitting is used to divert the flow direction of pipe? ›

1. Elbow (45 Deg and 90 Deg) An elbow is generally used to change the direction of flow of liquid between two pipes. If the two pipes are of different diameters then the elbow is called as a reducer.

What is stub in and stub on in piping? ›

Stub-in vs Stub-on Piping Connection

As explained above, Stub-in is used when the run pipe and branch pipe has a difference of more than one size. On the contrary, Stub-on pipe branch connection is applicable when the branch pipe isequal to run pipe only only one size lower than the header pipe.

How long can a pump suction line be? ›

Keep Suction Piping as Short as Possible

Include a straight-run pipe length equal to five to 10 times the pipe diameter between the pump inlet and any obstruction in the suction line. Obstructions include valves, elbows, “tees,” etc.

What is the name of the pipe fitting? ›

When two ends of pipes are joined, the pipe fitting used is called union. A union is made of three parts namely a nut, a male end and a female end. The male and female ends are assembled with the support of the nuts, and necessary pressure is made to connect the joint.

Why is eccentric better than concentric? ›

Eccentric contractions can increase muscle strength more than concentric contractions, for two main reasons [4]. First, as your muscles get bigger, their fibers are split into a greater number of sarcomeres, which increases the overall strength of the muscle.

Is eccentric positive or negative? ›

Eccentric refers to the “negative” portion of the movement, while concentric is the “positive”. For example, when you do a barbell curl, the concentric portion is the lift or curl up. The eccentric portion is when the weight is lowered back to the starting position.

How do you remember concentric and eccentric? ›

Concentric movements occur when the muscles contract (shorten), and eccentric movements occur when the muscles lengthen.

What is a reducing tee? ›

Reducing tee, like all pipe tees, is in the shape of T with two ends of equal size and the third one slightly smaller. In other words, reducing tee is a type of pipe fitting in which the branch port size is smaller than the ports of the run.

How many inlets does a straight or reducing tee have? ›

One is known as a straight tee, and the other is a reducing tee. On a straight tee, all three outlets are the same nominal pipe size. A reducing tee has a branch that is a smaller line size than the header.

Why pump suction is greater than discharge? ›

Suction pressure diameter is usually 1 size higher than discharge, because we need minimum resistance in the suction side to reduce the losses and increase the NPSHa.

What will happen if we reduce the discharge pipe size of a pump? ›

If you had the ability to instantly increase the pipe size then the friction head would drop, the flow would increase and the pump would be operating on a lower part of its curve. The reverse would happen if you could decrease the pipe size, the pump would operate higher on its curve and the flow would diminish.

How does cavitation occur in pumps? ›

Cavitation occurs when the liquid in a pump turns to a vapor at low pressure. It occurs because there is not enough pressure at the suction end of the pump, or insufficient Net Positive Suction Head available (NPSHa). When cavitation takes place, air bubbles are created at low pressure.

Is the suction line bigger than the discharge line? ›

The suction nozzle is one size larger than the discharge nozzle.

Does pipe size affect water pump? ›

In a pipe with a smaller diameter, more of the liquid comes into contact with the pipe's interior surface area, slowing it down. That requires more output from the pump to make up the difference. In a larger-bore pipe, less of the fluid rubs up against the pipe and thus drops in velocity, requiring less energy.

What is the suction side of a pump? ›

The inlet, or suction side of a pump is the point of lowest pressure in a given pump. For positive displacement pumps, the lowest pressure occurs just prior to rotor meshing; for centrifugal pumps, lowest pressure is near the eye of the impeller.

How do you find the eccentricity of a pipe? ›

Eccentricity can be checked by determining the wall thickness around the tube at any cross section to establish maximum and minimum. The tube's eccentricity (in mm) at that cross section would be one half the difference between the minimum wall thickness (t2) and the maximum wall thickness (t1).

What is reducer in piping system? ›

A reducer is a component in a piping system that changes the pipe size from a larger to a smaller bore. A reducer allows for a change in pipe size to meet flow requirements or to adapt to existing piping.

What is ovality in pipe? ›

Simply put, ovality occurs when a pipeline 'ovals' from its original circular shape - the pipe is no longer perfectly round. Although any pipe will oval under the right amount of loading, pipelines with high D/t ratios (diameter over thickness) are most susceptible.

How many types of elbow are there? ›

There are three main types of elbow: long radius elbows, short radius elbows, and impact/vortex elbows.

What is the meaning of reducer? ›

a person or thing that reduces. Photography. an oxidizing solution for lessening the density of an exposed negative. a developing agent.

How are pipes classified? ›

The classification of pipes are schedule and nominal diameter. Pipe is typically ordered using the Nominal Pipe Size (NPS) standard and by specifying a nominal diameter (pipe size) and schedule number (wall thickness).

What are the three types of fittings? ›

The Three Types Of Fit
  • Clearance Fit. Clearance fits allow for loose mating, where free movement is important and a certain amount of play is desired. ...
  • Interference Fit. An interference fit will be much tighter than a clearance fit. ...
  • Transition Fit. A transition fit would fall between a clearance and interference fit.
