More about concentric reducers:

These metallurgical products are applied to change the diameter of the pipeline. Their use does not disturb the flow of liquids or other substances. Another name for this type of stainless reduction is symmetrical reducers. The shape of the wall of the stainless steel concentric reductions has the shape of a straight cone, in contrast to the eccentric reducurers, the wall of which has the form of a spherical cone. Stainless steel concentric reducers are chosen by installers because of their good fluid kinetics.
