When the centers of both the circles are at the same point.
There is such a point only if all the circles are concentric.
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.
These are the crests and troughs of the wave (in a ripple on the surface of water or other liquid).
Concentric swage is used for small bore piping while concentric reducer is used for large bore piping. Zach

Concentric Circle
Circles in the same plane with the same center are concentric circles.

concentric circles
Concentric circles have the same center. They are not necessarily the same size. If two concentric circles have the same area, then they are congruent, meaning they coincide when superimposed.
Concentric circles
Non concentric circles are circles that do not share the same center point.
"Concentric" means to have a common center. Concentric circles are circles of different sizes that all have the same center -- like a bullseye target.
Concentric circles are the circles with the same center therefore they do not cross with each other as the "center is not considered a point on the circle". An exception would be two circles that are concentric and have the same radius, in which case the circles are indistinct and every point of the circles is an intersection.
