Introduction and Technical Structure
In the execution of modern ductwork systems, speed and precision in connecting components are of high importance. Kian Fan Industrial Production Group, by producing the connector with TDC flange, has provided a smart and efficient solution to accelerate the installation process. The structure of this product includes a rectangular duct piece of standard length in which TDC flanges are installed on both ends in the factory using machinery.
This production method ensures that the connector is sent to the workshop as a complete, ready-to-use piece. The connector body is made of high-quality galvanized sheet and features reinforcing beads for added strength. The TDC flanges installed on them are engineered with high precision to perfectly match other system components. This structural integrity minimizes installation errors and guarantees the final quality of the connection.

Key Features and Advantages
The most important feature of Kian Fan's connector with TDC flange is the significant reduction in installation time. Since the flanges are pre-installed on the piece, the worker at the workshop site does not need to spend time adjusting and installing the flange on the cut edges of the duct; they simply need to place the piece and install the cleats. This effect, in large projects with thousands of meters of ducting, leads to considerable savings in labor costs and project delivery time.
Excellent sealing is another advantage of this product. Because the flanges are installed in the factory under controlled conditions, their alignment is guaranteed, and using EPDM sealing tape creates a leak-free connection. The high strength of the connection resulting from the TDC flange makes the connector suitable for withstanding positive and negative pressures. Additionally, the integrity of the piece gives the ductwork network a neat and professional appearance.

Specialized Applications
Kian Fan's connector with TDC flange has applications in all projects using rectangular ducts. In office and commercial buildings, these connectors increase work progress speed for connecting main branches along the path. In factories and industries, where there is often a need for repair or rerouting of ducts, using prefabricated connectors facilitates disassembly and reassembly.
Also, in central HVAC systems where there are strict standards regarding air leakage, using factory-prefabricated and controlled components such as the TDC connector reduces the risk of human error. This product is also very suitable for connecting rectangular ducts to auxiliary equipment that has TDC flange outlets.

Conclusion
The connector with TDC flange from Kian Fan Industrial Production Group, relying on prefabrication and engineering precision, is a modern solution for optimizing the execution of rectangular duct systems. Choosing this product guarantees increased productivity, reduced costs, and high connection quality in ventilation networks.
