Ductile Iron Grooved Tee for Fire Protection Piping Systems

A fire protection grooved tee is a mechanical pipe fitting designed to create a branch connection in piping systems while maintaining a reliable grooved connection. It allows fluid flow to be divided into two directions, making it an essential component in fire sprinkler and industrial piping networks.

Compared with traditional welded or threaded tee fittings, grooved tees provide faster installation, easier maintenance, and improved flexibility through mechanical coupling connections.

DTC supplies ductile iron grooved tees for fire protection systems, including equal tees and reducing tees. Manufactured with durable ductile iron bodies and reliable sealing systems, our grooved tees are widely used in sprinkler systems, HVAC installations, water distribution, and industrial piping projects.

Key Features of Grooved Tee

Reliable Branch Connection

Grooved tees provide a secure connection point for branch pipelines while maintaining system integrity.

Fast Mechanical Installation

The grooved connection design eliminates welding and reduces installation time.

High Strength Ductile Iron Construction

Ductile iron provides excellent durability, impact resistance, and long service life.

Flexible System Design

Available in equal and reducing configurations to meet different piping layouts.

Suitable for Fire Protection Applications

Designed for reliable performance in sprinkler and fire suppression systems.

Technical Specifications

Types of Fire Protection Grooved Tees

Equal Grooved Tee

An equal tee has the same diameter for the run pipe and branch outlet.

Advantages:

• Standard branch connection
• Simple pipeline design
• Easy installation

Applications:

• Fire sprinkler networks
• Water distribution systems
• HVAC piping

Reducing Grooved Tee

A reducing tee has a smaller branch outlet compared with the main pipeline.

Advantages:

• Allows different pipe sizes
• Reduces installation space
• Optimizes pipeline design

Applications:

• Sprinkler branch lines
• Building services
• Industrial piping systems

Mechanical Tee (Grooved Outlet Tee)

A mechanical tee creates a branch connection by using a bolted outlet housing mounted directly on the pipe.

Advantages:

• No need for cutting large sections of pipe
• Fast branch installation
• Space-saving solution

Applications:

• Fire sprinkler systems
• HVAC systems
• Retrofit projects
