Introduction
In piping systems, every fitting plays a vital role. One such component is the MS Eccentric Reducer. It ensures smooth flow by connecting pipes of different diameters while keeping one side flat.
At Fortis Forge, we manufacture top-quality eccentric reducers with precision and strength. Our reducers meet global standards and deliver reliable performance in demanding environments. This blog explains their design, uses, advantages, and why industries trust Fortis Forge.
What Is an MS Eccentric Reducer?
An MS Eccentric Reducer is a pipe fitting made from mild steel. Unlike concentric reducers, its centerlines are not aligned. One edge remains flat, while the other tapers down to connect with a smaller pipe.
Key Features:
- Flat side prevents air accumulation
- Smooth flow transition with reduced turbulence
- Manufactured from durable mild steel

Why Use Mild Steel for Eccentric Reducers?
Mild steel provides strength, flexibility, and cost efficiency. These properties make it ideal for eccentric reducers.
Advantages of Mild Steel:
- Excellent weldability for installation
- Strong enough to handle pressure
- Affordable compared to alloy alternatives
- Resistant to impact and wear
Fortis Forge uses high-grade mild steel to guarantee consistent performance and durability.
How Does an MS Eccentric Reducer Work?
The eccentric reducer works by gradually changing pipe diameter. The flat side helps maintain proper fluid flow in horizontal lines.
Process Explained:
- Fluid enters through the larger opening.
- It passes through the sloped conical body.
- Fluid continues into the smaller pipe without forming air pockets.
This design prevents cavitation and improves system efficiency.


Applications of MS Eccentric Reducers
MS Eccentric Reducers are widely used in industries where proper flow is essential.
Common Uses:
- Oil and gas transmission
- Water treatment plants
- Chemical processing facilities
- Power generation plants
- Food and beverage industry
- HVAC and plumbing systems
They ensure consistent performance across varied conditions.

MS Eccentric Reducer vs. MS Concentric Reducer
Both reducers connect pipes of different diameters, but their functions differ.
Feature | Eccentric Reducer | Concentric Reducer |
---|---|---|
Alignment | Flat side, offset center | Centerlines aligned |
Best Use | Horizontal piping systems | Vertical piping systems |
Flow Control | Prevents air pockets | Balanced flow |
Fortis Forge supplies both types, ensuring customers find the right fit.
