Comparison of core differences

 

feature

Concentric reducer

Eccentric reducer

geometric shape

It has a conical frustum shape, with concentric central axes at both ends.

It has an eccentric conical frustum shape, with one side of the pipe wall being straight.

centerline

On a straight line.

Not on a straight line, offset occurs.

Main applications

Vertical pipeline.

Horizontal pipeline.
