Overview
Product overview
Buttweld Concentric Reducer play a crucial role in piping systems by seamlessly reducing the pipe size from a larger diameter to a smaller one. This essential fitting ensures smooth and efficient flow transition while maintaining optimal performance in various applications.
Our Buttweld Concentric Reducers are available in a variety of materials, including copper and stainless steel, carefully chosen for their corrosion resistance, strength, and compatibility with different fluids. We also offer custom-made solutions to meet specific project requirements, ensuring maximum flexibility and adaptability.
A Concentric Reducer is designed to connect pipes of different sizes in a straight line, achieving a uniform reduction in diameter from one end of the fitting to the other. This gradual reduction minimizes turbulence in vertical piping systems, ensuring smooth flow and efficient operation.
Fortune Fittings Private Limited takes pride in offering Buttweld Concentric Reducers with accurate dimensions and precise manufacturing, guaranteeing a proper fit and optimal flow rate in piping systems.
What is a Buttweld Concentric Reducer?
A Buttweld Concentric Reducer is a type of pipe fitting used to connect pipes of different diameters in a straight line while maintaining a uniform centerline. It features a conical shape with a larger diameter at one end and a smaller diameter at the other, resulting in a gradual reduction in pipe size. This reduction facilitates smooth flow transition and minimizes turbulence in vertical piping systems.

Technical notes
How the component behaves in the line, and the details to settle before an order is placed.
How it behaves in the line
- Concentric: centrelines of inlet and outlet are collinear
- Cone half-angle ≤ 7° recommended to avoid flow separation at high velocities
- Length H (overall) per ASME B16.9 depends on size combination
- Wall schedule may differ at large and small ends: confirm both ends during ordering
Confirm when ordering
- Specify Concentric or Eccentric: they are not interchangeable
- Give both sizes: e.g. 4" × 2" (large end × small end)
- Confirm wall schedule on both ends: may differ for cross-schedule combinations
Dimensions, wall thicknesses and pressure classes are in the dimension tables; the governing standards are summarised on the standards reference.
