The difference between concentric and eccentric reducers is that, as the name suggests, the center of the circle is a centerline, and the eccentricity is the outer diameter of a horizontal line. Most of the eccentricity is used to take the liquid pipeline. To prevent the accumulation of liquid, the vertical pipeline is more concentric; if it is a gas, the concentric pipeline is generally used.
