DTC‑GROOVED ELBOW-DI Series
DTC supplies high-quality ductile iron grooved elbows for fire protection piping systems, including 90° and 45° grooved elbows. Designed for fast installation, reliable sealing, and long service life in sprinkler, HVAC, and industrial piping applications.
A fire protection grooved elbow is a mechanical pipe fitting designed to change the direction of piping systems while maintaining a reliable grooved connection. It is commonly used in fire sprinkler systems, hydrant networks, HVAC systems, and industrial piping applications.
Unlike traditional welded or threaded fittings, grooved elbows use a mechanical coupling connection, allowing faster installation, easier maintenance, and improved system flexibility.
DTC supplies ductile iron grooved elbows manufactured for reliable performance in fire protection systems. Available in common configurations including 90-degree elbows and 45-degree elbows, our products provide efficient pipeline routing and secure connections for commercial, industrial, and infrastructure projects.
Grooved connections allow quick assembly without welding, reducing installation time and labor costs.
Ductile iron provides excellent mechanical strength, durability, and impact resistance.
Compatible rubber gaskets ensure leak-resistant connections under various working conditions.
The curved elbow design helps maintain efficient fluid flow while changing pipeline direction.
Designed for sprinkler and fire protection networks requiring reliable and durable piping components.
