Pipe Reducer

A pipe reducer is a fitting used to connect pipes of different diameters. Its primary function is to achieve a reduced diameter connection within a piping system. It can smoothly change the flow rate and pressure of the medium within the pipe, ensuring smooth operation of the piping system.

Main Types

1. Concentric Reducer

•  Conical shape with a consistent centerline
•  Used for vertical pipes or where top/bottom flushing is required
•  Reduces cavitation and turbulence

2. Eccentric Reducer

• One side is straight, the other is beveled
• Commonly used in horizontal pipes to prevent gas accumulation or liquid sedimentation
•  Categories include “flush top” and “flush bottom” types

Material Options

We offer pipe reducers in a variety of materials to meet different application requirements:

•  Carbon steel (ASTM A234 WPB)
•  Stainless steel (304, 316, 316L, etc.)
