if we use concentric reducer at suction of pipe ,due to high turbulence flow of fluid ,some vapour pressure generate which generate bad effects on impeller of pump ,which decrease pump efficiency , so to avoid this problem the eccentric reducer's use in pump suction

What is usage of concentric and eccentric pipe reducer?

An eccentric reducer is mostly used to force air in a direction, normally towards a pump or airvalve so that it does not get trapped inside the pipework.


What are the merits and demerits of replacing an eccentric pipe reducer with a concentric one?

Very depend on the application, concentric pipe had lower pressure drop and better flow distribution. However, in many case, eccentric pipe reducer is installed on propose to allow liquid drainage from reducing in horizontal pipe.


What is the difference between eccentric and concentric reducer?

Concentric reducers are a symmetrical, conical shaped device that enlarges or reduces a pipes diameter equally about the centerline. An Eccentric reducer is not Symmetrical about the centerline. For example, envision the flow through a gravity based pipe... picture it in terms of an elevation section view... the eccentric reducer maintains the flowline (a straight continuous line along the bottom) while the pipe size decreases from the top down.

What is the function of Suction valve?

the suction valve is transfered fluid one pipe to another pipe at a specific pressure and quantity.


What is the function of air vessel in reciprocating pump?

the function of air vessel is to accumulate excess quantitiy of water flowing in the suction pipe or delivering pipe compressing the air inside the vessel


What is use of pipe nipple?

Pipe nipple is use as connector to both pipe which have female end. It does not same as pipe reducer which nipple has same diameter throughout both end and threaded. Pipe reducer has different diameter for both end and it is use to join different pipe diameter.


What is a connector reducer?

In plumbing it is a pipe connector that also reduces the size of the pipe so two different sizes can be spliced. If you want to connect a 1" pipe to a 3/4" you would put a 1' to3/4" reducer there.


How do you make reducer from pipe?

By placing a smaller pipe insider the larger one and weld /braze the gap

What is a pipe fitting that join a smaller to a larger pipe what is it called?

You would have to get the larger sizes cuppler with a reducer to the smaller size and then join it together
