- A steel pipe reducer is a component used in the pipelines to reduce its size from large to small-bore in accordance with the inner diameter.
Applications of Steel Pipe Reducer
The usage of a steel reducer is carried out in the chemical factories and power plants. It makes the piping system reliable and compact. It safeguards the piping system from any kind of adverse impact or thermal deformation. When it is on the pressure circle, it prevents from any type of leakage and is easy to install. The nickel or chrome-coated reducers extend the product life, useful for high vapor lines, and prevents corrosion.

Eccentric Reducer
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 a 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.
Socket Weld Reducer vs Butt Weld Reducer
Socket weld reducer also called socket weld insert, has three types 1, 2 and 3. Manufacturing standards comply to ASME B16.11.
The Socket Weld resists ½ of the strength of butt welding, so it is used for small-diameter pipes possessing a diameter of NPS 2 or less. Butt Weld has good strength, as it is suitable for high pressure and temperature pipelines.
Butt weld reducer ends in plan or beveled, manufactured in accordance with ASME B16.9 and welding process according ASME B16.25.
Pipe Reducer Material Types
Carbon Steel Reducer vs Stainless Steel Reducer
The reducers can be made of Carbon Steel, Alloy, or Stainless steel and much more. In comparison to the Stainless Steel Reducer, Carbon Steel Reducer possesses high-pressure resistance, higher strength, and wear resistance but this can be easily corroded.
Carbon Steel Reducer material standards and grades:
A234 WPB, A420 WPL6, MSS-SP-75 WPHY 42, 46, 52, 56, 60, 65 and 70.
For Stainless Steel Reducer:
ASTM A403 WP 304, 304L, A403, 316, 316L, 317, 317L, 321, 310 and 904L, etc.
For Alloy Pipe Reducer:
