By placing a smaller pipe insider the larger one and weld /braze the gap
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.
You would have to get the larger sizes cuppler with a reducer to the smaller size and then join it together
A pipe fitting can be anything from a bell reducer to a flange to a nipple. The purpose of each one is different, for a nipple it is to extend the pipe or add threads, depending, a flange is used to create a secured connection between the two pipes and a bell reducer increases pressure while lowering velocity.

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.
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.
It may be in the main cold water shutoff or if you have a water pressure reducer it may be in the reducer manifold

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

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.
Reducer
With large diameters like that you will most probably need to insert a weld-on 12 inch - 10 inch reducer at the point where the reduction is required. The pipe and reducer perimeter edges should be bevelled, say 45 degrees, for good weld penetration especially if the pipe conveys fluid under pressure.
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.

A fitting that makes it possible, for example, to glue a piece of 2" pipe into a 3" fitting (if you have a 3" x 2" bushing, that is).
