Description
The Reducer Conical is the most common fitting used to transition between two pipe sizes while maintaining a shared center axis. Its symmetrical, cone-like shape allows for a gradual change in fluid velocity, making it ideal for systems where maintaining a laminar flow is critical to prevent turbulence and pressure surges. These are the preferred choice for vertical pipelines where space and alignment are straightforward.
Technically, the Reducer Conical is engineered to handle significant hydraulic loads. Because the flow is centered, the mechanical stress is distributed evenly across the fitting’s walls. In sanitary applications, these reducers are manufactured using high-precision forging to ensure the internal transition is perfectly smooth, preventing “step” areas where product could accumulate or cause shear stress on sensitive biological fluids.
Available in a wide range of schedules and pressure ratings, our Reducers Conical are built from certified stainless steel (304/316L). They meet international standards for both industrial heavy-duty use and sterile pharmaceutical environments, providing a leak-proof and durable solution for any diameter-change requirement.
Key Features of Reducers Conical
- Symmetrical Design: Maintains a consistent centerline for easy piping alignment.
- Smooth Flow Transition: Minimizes turbulence and backpressure during diameter changes.
- Balanced Stress Distribution: Ideal for high-pressure vertical installations.
- Sanitary Finish: Available with high-polish or electropolished internals (Ra < 0.4 µm).
- Versatile Compatibility: Suitable for butt-weld, tri-clamp, or threaded connections.
Technical Specifications for Reducers Conical

- Sizes: From 1/2″ x 1/4″ up to large-scale industrial diameters.
- Standards: Compliance with ASME BPE, DIN, SMS, and ISO.
- End Types: Beveled for welding, clamp-on, or flange-ready.
- Pressure Rating: Rated according to wall thickness (Sch 5 to Sch 80).
Uses and Applications of Reducers Conical
- Vertical Pipelines: The standard choice for up-and-down fluid transport.
- Pump Discharge: Managing flow as it exits a pump and enters a larger header.
- HVAC Systems: Transitions in steam and chilled water distribution.
- Food & Beverage: Transitioning between process tanks and filling lines.
- Pharmaceuticals: Symmetrical reductions in sterile liquid transfer lines.
Usage and Maintenance Recommendations for Reducers Conical
- Avoid using conical reducers in horizontal suction lines for pumps, as they can trap air.
- Ensure that the weld penetration is full and smooth to maintain the sanitary integrity.
- Periodically check for erosion at the transition zone in high-velocity slurry applications.
- Verify that the piping supports can handle the weight shift at the point of diameter change.
Frequently Asked Questions about Reducers Conical
When should I choose a Conical Reducer over an Eccentric one?
Choose a Conical (Concentric) reducer for vertical lines or anytime you need to keep the piping on the same centerline. Use them where drainage or air pockets are not a concern.
Does a conical reducer cause pressure drop?
Any change in diameter causes some friction, but the gradual slope of a conical reducer is designed to make that transition as efficient as possible compared to a sudden bush-style reduction.
Are they suitable for high-viscosity products?
Yes, the centered flow helps keep viscous products moving steadily without the “dead zones” that can occur in asymmetrical fittings.
