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.
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.

There are wood pipes, glass pipes, and even marble pipes.

it's steel pipe without any processing and packing.
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.
Let me know about the usage of Eccentric and Concentric pipe intersection in oil and gas industry? What are the major differences and concerns about Eccentric and Concentric pipe intersection in oil and gas industry?

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

To install an eccentric reducer, align the top flat side of the reducer with the upper pipe, ensuring that the bottom side is offset from the centerline of the lower pipe. Once aligned, weld or connect the reducer to the pipes using the appropriate method for the specific material being used. Finally, inspect the installation for proper alignment and seal before putting the system into operation.
An eccentric reducer is typically used in piping systems to connect pipes of different diameters, with one side of the reducer having a larger diameter than the other. It helps to maintain the flow velocity and reduce the pressure drop in the system by gradually transitioning the pipe diameter.

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.
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.
By placing a smaller pipe insider the larger one and weld /braze the gap
You would have to get the larger sizes cuppler with a reducer to the smaller size and then join it together
