ANSI B16.9 Reducer Konċentriku (magħruf ukoll bħala reducer konċentriku jew twaħħil ta 'reducer konċentriku) huwa kkaratterizzat billi jkollu dijametri differenti tal-pajpijiet fiż-żewġt itruf iżda b'linja ċentrali maqsuma. Dan id-disinn jiżgura tranżizzjoni bla xkiel għall-fluss tal-fluwidu, li jimminimizza t-taqlib u t-telf tal-pressjoni. Meta mqabbel ma 'tnaqqis eċċentriku, tnaqqis konċentriku huwa aktar adattat għal sistemi ta' pipeline orizzontali fejn hija meħtieġa stabbiltà ta 'fluss ta' fluwidu għoli.
