Tee for fire-resistant duct

Tee fittings for fire-resistant ducts are specialized components designed to maintain the integrity of electrical and automation cabling pathways in critical fire safety zones. These tees, typically constructed from galvanized steel or stainless steel, feature a three-way junction that allows for branch routing of cable trays or conduits while preserving the fire-resistant rating of the entire duct system. Key technical parameters include material thickness (often 1.5mm to 2.0mm), temperature resistance up to 1000°C for 60-120 minutes, and compatibility with standard duct widths from 200mm to 600mm. They are available in various configurations such as equal tees (same width on all branches) or reducing tees (different branch widths), with mounting options including bolted flanges or welded connections. These fittings are essential for ensuring that fire-rated barriers remain unbroken in industrial installations.

These tees are primarily deployed in fire-resistant duct systems within industrial automation plants, data centers, commercial buildings, and critical infrastructure facilities. They are installed in cable management pathways that must comply with strict fire safety regulations like BS 476, DIN 4102, or EN 1366. Common environments include electrical rooms, control cabinets, and vertical risers where cables must be routed through fire compartments. The tees facilitate branch connections for power distribution, control signals, and data networks while maintaining the required fire resistance rating (typically E30, E60, or E90). They are also used in ventilation systems for smoke extraction and in emergency power supply routes.

Key subcategories include equal tees (e.g., model FRD-TEE-300-300-300 for 300mm ducts), reducing tees (e.g., FRD-TEE-400-400-200), and flanged tees (e.g., FRD-TEE-FL-500-500-500). The article code structure typically follows the pattern: FRD-TEE-[Width1]-[Width2]-[Width3]-[Option], where Width1 is the main run width, Width2 and Width3 are branch widths in millimeters. For example, FRD-TEE-600-600-300-SS indicates a stainless steel tee with 600mm main run and 300mm branch. Other variants include insulated tees for thermal protection and pre-drilled tees for easy mounting.
