Concentric Reducer

Product Introduction

A reducer, also known as a reducing coupling, is a stainless steel pipe fitting designed to connect pipes of differing diameters within a piping system. Its primary function is to transition between larger and smaller pipe sizes while maintaining smooth fluid flow. There are two main types of reducers: concentric reducers, which have aligned centerlines at both ends and are commonly used for vertical piping where flow symmetry is important; and eccentric reducers, where one side is offset, making them ideal for horizontal lines where air pockets must be avoided or specific alignment is required.

Core Technology

Concentric reducers are commonly used in vertical pipelines or gas transmission, while eccentric reducers are primarily applied in horizontal pipelines to prevent liquid accumulation or gas trapping.
