Product Overview

Butt weld concentric and eccentric reducers, NPS 3/4''-48'' (body also cites 1/2-56" and up to 80"), in carbon, stainless and alloy steel, for changing pipe diameter. A butt-weld reducer joins pipe of larger diameter to smaller; the reduction approximates the average of the two pipe diameters. Concentric reducers taper uniformly keeping symmetry on a common centerline; eccentric reducers keep one side flat with the smaller outlet offset.

Applications and Ordering

Diameter transition in piping systems. Horizontal pipe runs where top or bottom must stay level (eccentric) Matching hydraulic flow requirements. Adapting existing piping of differing sizes. Nozzle or diffuser duty depending on air-flow Mach number. Send your requirement for a quotation.
