Which pipe fitting is most commonly used with ductile iron pipe for changes in direction?

The most commonly used fitting for changes in direction with ductile iron pipe is the elbow fitting. Elbow fittings come in various angles, typically 90 degrees and 45 degrees, allowing them to create sharp turns or gradual bends in the piping system. This flexibility in direction is essential for maintaining the flow of water or other fluids in a controlled manner.

Ductile iron pipe is known for its strength and durability, making it a popular choice in water distribution systems. The elbow fitting complements these properties by offering a robust connection that can withstand pressure and environmental conditions. This fitting is integrated within the system to facilitate necessary turns without compromising the overall integrity of the piping system.

In contrast, bend fittings, while also capable of changing direction, are less commonly specified than elbow fittings. Connector fittings are primarily used to join two segments of pipe rather than to change directions. Clamp fittings serve specific purposes, often used for repairing or securing pipes rather than altering their direction of flow. Therefore, the elbow fitting is the preferred choice in applications involving changes in direction for ductile iron piping systems.
