Ductile Iron Double Flanged 90° Duckfoot Elbow

When designing robust and efficient drainage and sewer systems, selecting the right fittings is paramount for ensuring longevity, structural integrity, and optimal flow. The Ductile Iron Double Flanged 90° Duckfoot Elbow stands as a superior solution for redirecting wastewater flows in pressurized and non-pressurized systems. This specialized fitting combines the inherent strength and corrosion resistance of ductile iron with a unique offset "duckfoot" base, providing exceptional stability and preventing settlement in trench applications. It is engineered for direct, flanged connection to pipes, facilitating easy installation and maintenance. For projects requiring precise 90-degree directional changes with enhanced support, our Double Flanged 90 Degree Duckfoot Bend Ductile Iron Pipe Fittings offer reliable performance. Similarly, systems needing a compact turn can benefit from a Ductile Iron Double Flanged Short Radius 90° Bend, while the versatile Double Duck Foot Flanged Bend provides an alternative configuration for specific layout requirements.

The Ductile Iron Double Flanged 90° Duckfoot Elbow is manufactured to exacting international standards, ensuring compatibility and reliability in municipal, industrial, and commercial infrastructure. Its design features a double-flanged configuration at both ends, allowing for secure bolting to adjoining flanged pipes or valves, creating a rigid, leak-resistant joint. The integral duckfoot base extends the footprint of the fitting, distributing load more evenly across the bedding material and significantly reducing the risk of point loading and subsequent pipe movement or joint stress. This makes it particularly suitable for installations in unstable soils or areas with high traffic loads. The interior surface is typically cement-mortar lined for sustained hydraulic capacity and corrosion protection, while the exterior is coated with a protective layer, often epoxy, to resist aggressive soil conditions.
