Concentric Reducer

A concentric reducer is a cone-shaped mechanical fitting that joins two pipes or tubes of different diameters on the same axis.It allows for connecting a large pipe to a smaller pipe by means of welding. A concentric reducer allows welded connection between two pipes with the same center line.

Special Features

Horizontal liquid reducers are usually eccentric, with a flat top that avoids the accumulation of air bubbles in the system. Eccentric reducers are used on the suction side of pumps to stop air trapping in the tubing. The gradual accumulation of air in a concentric reducer can result in a large bubble, causing the pump to stall or cavitation when drawn into the pump. Horizontal gas reducers are often eccentric with smooth bottoms, allowing condensed water or oil to drain at low stages.

معيار: ANSI B16.9 / 16.28, ASTM A53/A106, API 5L, ASME B36.10M---1996, DIN2605 / 2615 / 2616, JIS P2311/2312

Surface treatment: Transparent oil, rust-proof black oil or hot galvanized.

Based on different materials, pipe reducers include carbon steel reducer, stainless steel reducer, and alloy steel reducer etc.
Depending on their construction, pipe reducers contain threaded reducer, tapered reducer and anti-roll reducer etc.

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.

Manufacturing Process of Steel Pipe Reducer

There are versatile manufacturing processes for the reducers. These are made of welded pipes with the required filling material. However, EFW and ERW pipes cannot use the reducer. To manufacture forged parts, different kinds of methods are used including cold and hot forming processes. It includes the ‘Outer Die Method.’

Outer Dia Method

It is the most common method for manufacturing the steel pipe reducer. The pipe is cut and pressed in the outer die whereas, one end of the pipe is compressed into the smaller size. This method is fit for manufacturing small and medium-size reducers.

Connection Types of Pipe Reducer

Ranges from different connection types, pipe reducer could be classified with socket weld reducer and butt weld reducer.
