ASME B16.9 Reducer 6inchX4inch Material ASTM A234/WPC

This reducer consists of the symmetrical and conical shaped fittings that enlarge or reduce the diameter equally about the center line. For an example, when 1” pipe transitions to ¾” pipe, then the top or bottom of the pipe do not remain level.

Product Details

      Butt weld reducer can adjust the flow rate and speed. One end welded with a large diameter pipe and another end with a smaller OD pipe. It has two types:

Concentric and Eccentric Reducer.   

       Reducer is a kind of fitting that be used for reducing piping size. There are 2 types reducer as follows:

a. Concentric reducer: have a central axis (centerline) of the section between the large and small.

b. Eccentric reducer: the central axis has a different (offset) between a large section and small.

      Use these concentric reducers to connect two carbon steel pipes with different inside diameters. The carbon steel construction is stronger than stainless steel, is very resistant to wear, and can withstand high pressure, but is also susceptible to corrosion.   

Concentric reducer is most commonly used and often eccentric reducer used in piping in about pump and pipe rack area.

       Concentric Reducer vs Eccentric Reducer Differences

Concentric reducers are widely used while eccentric reducers are applied to maintain the top and bottom pipe level. Eccentric Reducers also avoids trapping of air inside the pipe, and Concentric Reducer removes noise pollution.
