A grooved concentric reducer is a pipe fitting designed to seamlessly connect two pipes of different diameters while maintaining a shared centerline. It ensures smooth fluid flow transition, minimizes turbulence, and supports quick installation via grooved couplings. Ideal for HVAC, fire protection, and industrial piping systems, it eliminates welding and allows for flexibility in thermal expansion.
Grooved Concentric Reducer
No welding or special tools are required, and quick assembly is achieved through grooved clamp connections that are 30%-50% more efficient to install than flanged connections.
Triple seal design, C-ring + grooved press fit + metal bite. Withstands pressures ranging from 300 psi (carbon steel) to 600 psi (stainless steel) for fire protection and industrial high-pressure systems.
Compatibility with a wide range of piping materials, such as galvanized steel, stainless steel, copper, etc., simplifies integration of mixed-material piping systems.
Wide range of temperature resistance, with conventional rubber seals supporting -30°C to 120°C, and upgradable to 400°C for high-temperature scenarios.
Specialized groove tools must be used to compress the pipe to ensure that the groove depth (1.5-3.0 mm) and width match the fixture and to avoid mechanical failure.
Weight Reference Table (Carbon Steel Material)
| Nominal Diameter (DN) | DN (inches) | SCH40 Weight (lbs) | SCH80 Weight (lbs) |
|---|---|---|---|
| DN50 | 2″ | 2.1 | 4.0 |
| DN100 | 4″ | 12.3 | 21.2 |
| DN200 | 8″ | 47.6 | 69.7 |
| DN300 | 12″ | 123.5 | 214.8 |
- Stainless steel weights are approximately 1.2x of carbon steel (e.g., DN50 SCH40 ≈ 2.5 lbs).
- Data based on ANSI B16.11 standard (imperial units) and industrial supplier catalogs.
