Description
Stainless Steel Weld Eccentric Reducer
Stainless Steel Weld Eccentric Reducers are designed to transition between different pipe diameters while offsetting the centerline of the piping system. This asymmetrical reducer configuration is commonly used where maintaining a flat side through the transition is important for piping layout or flow requirements.
Available in Schedule 10 and Schedule 40, these butt weld reducers are manufactured from stainless steel raw material conforming to ASTM A312 and are produced and tested to recognized ASTM, ASME, ANSI, and MSS standards.

Eccentric Reducer Design
An eccentric reducer transitions from a larger pipe diameter to a smaller pipe diameter while offsetting the centerline between the two ends.
Unlike a concentric reducer, the eccentric profile provides a flatter side through the reduction, making it useful in piping layouts where the reducer geometry or orientation must help maintain a particular pipe elevation or flow arrangement.
Butt Weld Construction
These reducers use butt weld connections on both ends for permanent installation in compatible stainless steel piping systems. Precision-formed ends support proper alignment and fit-up before welding.
Confirm both pipe sizes, wall thicknesses, reducer orientation, material requirements, and welding procedures before fabrication or installation.
Schedule 10 vs. Schedule 40
Schedule 10
- Lighter wall option for compatible piping systems
- Useful where lower wall thickness is appropriate
- Manufactured and tested to applicable ASTM and ASME requirements
- Confirm both connecting pipe schedules before ordering
Schedule 40
- Heavier wall than Schedule 10
- Suitable where greater wall thickness is required
- Manufactured and tested to applicable ASTM and ASME requirements
- Confirm both connecting pipe schedules before welding
Eccentric vs. Concentric Reducers
Eccentric Reducer
- Offsets the centerline between pipe sizes
- Provides a flatter side through the transition
- Useful where piping elevation or reducer orientation is important
- Asymmetrical reducer profile
Concentric Reducer
- Maintains a common centerline
- Uses a symmetrical tapered profile
- Provides a centered transition between pipe sizes
- Different geometry from an eccentric reducer

Frequently Asked Questions
What is an eccentric reducer?
An eccentric reducer transitions between two different pipe sizes while offsetting the centerline between the larger and smaller connections.
How is an eccentric reducer different from a concentric reducer?
An eccentric reducer has an offset, asymmetrical profile. A concentric reducer keeps both pipe ends centered on the same axis.
What schedules are available?
The supplied product information lists Schedule 10 and Schedule 40 material options.
What connection type is used?
These reducers use butt weld connections for permanent installation in compatible stainless steel piping systems.
What material standard applies to the raw material?
The raw stainless steel material conforms to ASTM A312.
What manufacturing and testing standards apply?
The reducers are manufactured and tested in accordance with ASTM A403 and ASME SA403/SA403M.
What dimensional standards apply?
Applicable wall thicknesses and dimensions conform to ANSI B16.9, ANSI B16.28, and MSS SP-43.
Why use an eccentric reducer?
An eccentric reducer is useful where a piping system requires an offset transition rather than a centered reduction between two pipe sizes.
Where can I find reducer dimensions?

Is certification documentation available?
Yes. The Stainless Steel Certification Letter PDF is available in the Product Documents section above.
