Ductile Iron Grooved 90 Degree Elbow

Ductile Iron Grooved 90 Degree Elbow

Product Overview

The Ductile Iron Grooved 90 Degree Elbow is a specialized pipe fitting designed to facilitate a precise 90-degree change in direction within a piping system. Manufactured from high-strength ductile iron (also known as nodular iron), this fitting utilizes a grooved end connection system, allowing for rapid, bolt-free assembly when paired with compatible couplings. This design significantly reduces installation time and labor costs compared to traditional welding or flanging, making it a preferred choice for fire protection, water distribution, and industrial piping networks.

Key Features and Benefits

• Rapid Installation: The grooved ends allow for quick connection using standard grooved couplings, eliminating the need for welding, threading, or heavy flanging tools.

• High Strength & Durability: Constructed from ductile iron, which offers superior tensile strength and impact resistance compared to gray cast iron or malleable iron, ensuring longevity in demanding environments.

• System Flexibility: The grooved connection accommodates slight angular deflection and movement, absorbing vibration and thermal expansion/contraction within the pipeline.

• Corrosion Resistance: Typically finished with high-performance coatings such as red epoxy (for fire protection), green epoxy, or hot-dip galvanization to withstand harsh environmental conditions.

• Cost-Effective: Reduces installation labor and maintenance costs while providing a reliable, leak-tight seal.
