A conically shaped fitting that reduces or enlarges the diameter, but it is not symmetrical about the center line. This is used in pipe-work systems for reducing the diameter of a pipe from one size to larger or small size.
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.
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.
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.
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.
