We're professional double flange 90° duck foot bend manufacturers and suppliers in China, specialized in providing high quality products. We warmly welcome you to buy high-grade double flange 90° duck foot bend for sale here from our factory. For price consultation, contact us.
The Double Flange 90° Duck-Foot Bend, also known as a Tangential Bend or Foot Bend, is a specialized ductile iron pipe fitting designed to change fluid flow direction by 90 degrees while providing a stable base for supporting vertical loads.
Engineered for pump stations and pipeline systems, this fitting features a "duck-foot" or "boot" shape that rests directly on a concrete foundation. This unique design allows the bend to support the weight of the pump, valves, and vertical piping column, eliminating the need for additional pipe supports and reducing stress on the pipeline joints.
Manufactured in accordance with EN545 and ISO 2531 standards, our duck-foot bends are suitable for potable water, sewage, and industrial applications.
