Component Specifications

Definition
Branches and tees are essential ductwork components used to create divisions or junctions in airflow paths. Branches typically refer to fittings where a single duct splits into two or more directions, while tees specifically denote T-shaped junctions where a main duct connects perpendicularly to a branch duct. These components are critical for distributing or collecting air in complex ventilation networks, ensuring proper airflow to different zones or equipment.
Working Principle
Branches and tees operate on fluid dynamics principles, where airflow is divided or combined at junctions. The design minimizes pressure drop and turbulence through smooth transitions, optimized angles (typically 45° or 90° for tees), and proper sizing to maintain desired airflow rates. They ensure balanced distribution in systems by controlling flow resistance at split points.
Materials
Galvanized steel (most common), stainless steel (for corrosive environments), aluminum (lightweight applications), or fiberglass (insulated ducts). Thickness typically ranges from 0.6mm to 1.2mm depending on pressure requirements.

Frequently Asked Questions

What is the difference between a branch and a tee in ductwork?

While often used interchangeably, branches generally refer to any fitting that splits airflow into multiple paths, while tees specifically describe T-shaped fittings where a branch duct connects at a 90° angle to a main duct. Branches can include various configurations like wyes or laterals.

How do I select the right branch or tee for my ductwork system?

Consider airflow requirements, pressure drop limitations, space constraints, and material compatibility. Match the fitting size to your duct dimensions, choose appropriate angles to minimize turbulence, and select materials based on environmental conditions (humidity, chemicals, temperature).

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
