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.
concentric reducer are when wedon't want to change the centre line for fluid while eccentric is used when we want to change the centre line for fluid
The pump discharge reducer doesn't matter if it's concentric or eccentric. It's the pump SUCTION that needs to be an eccentric reducer that is always flat on top (F.O.T.) The eccentric reducer on the pump suction reduces pump cavatation (pump catching air).
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.
45 degree, 90 short radius degree ,T ,elbow,cap,concentric reducer, Tee and flange
gear box or speed reducer.
There are wood pipes, glass pipes, and even marble pipes.

Concentric swage is used for small bore piping while concentric reducer is used for large bore piping. Zach

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.
formula to find volume of an eccentric reducer
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
A concentric reducer is a round reducer in which the center line remains the same,like a bell. So, anytime you are piping and you need the center to remain constant a concentric is the right choice. the other type is called an ecentric. with it one side of the reducer remains flat. if you were piping across a floor for example.
To allow for proper drainage in a steam system Or sometimes to maintain a wet return
i dont know.... plz tel how to calculate
cavitation formed wen concentric reducer in used. but wat is the use of reducer in the both suction and discharge side of the pump. if we dost use (conc & ecc) reducer in the both sides.. there is not effect on pump
Doesn't matter
