Ductile Iron Pipe Bends

Ductile iron pipe bends are essential components in pipeline systems, enabling directional changes in the flow of fluids, typically at angles such as 90°, 45°, or custom configurations. These bends are made from ductile iron, a material known for its exceptional strength, flexibility, and resistance to wear and corrosion.

Key Features of Ductile Iron Pipe Bends:

1.Material Strength:

Ductile iron combines the rigidity of cast iron with the ductility of steel, allowing it to withstand high pressures and mechanical stresses.

2.Corrosion Resistance:

With proper coatings, such as bituminous coatings or epoxy linings, ductile iron bends exhibit excellent resistance to corrosion, extending their service life in various environments.

3.Versatility:

Available in various angles, radii, and sizes, these bends cater to a wide range of applications, including water distribution, sewage systems, and industrial processes.

Ease of Installation:

Ductile iron pipe bends are designed to integrate seamlessly with other components in a pipeline system using flanged, socket, or spigot connection.

Main Types of Bends：

1. By Angle

90° Bend: Used for sharp directional changes, common in compact installations.

45° Bend: Provides smoother directional changes, reducing flow resistance compared to 90° Bend.

22.5° and 11.25° Bend: Used for minor adjustments in the pipeline direction.

2. By Radius

Short Radius (SR) Bend:

Radius equal to the pipe diameter (R=1D).

Suitable for tight spaces but causes higher flow resistance.

Long Radius (LR) Bend:

Radius is 1.5 times the pipe diameter (R=1.5D).

Reduces flow resistance and is ideal for systems requiring smoother flow.

3. By Connection Type

Socket or Spigot Bend:

Designed for push-fit connections, commonly used in water supply systems.

Flanged Bend:

Equipped with flanges for easy bolted connections, often used in industrial setups.
