Introduction and Technical Structure
In air transfer systems, especially in industrial environments and large-diameter ducts where air flow pressure is high, connections must have sufficient strength to withstand mechanical forces and vibrations. Kian Fan Industrial Production Group has provided a reliable and standard answer to this engineering need by producing flanged connections. The structure of these connections is based on the use of galvanized flanges with a thickness of 2 to 4 millimeters, which are manufactured using advanced and precise machinery for bending and drilling.
The machining of production stages has resulted in Kian Fan flanges having high manufacturing precision, with dimensions that are completely standard and uniform. This precision during installation creates proper sealing and greater strength at the connection point. For small diameters where angle iron flange construction is not possible, plasma cutting technology is used so that the flange is cut flat from a flat sheet and then formed. This engineering approach ensures that flanged connections are available with the highest quality across all diameter ranges.

Key Features and Advantages
The most important feature of Kian Fan's flanged connections is their high strength and stability against pressure. These connections are designed to easily withstand high positive and negative pressures in industrial systems. The smooth internal surface of these connections, unlike some connection methods that cause turbulence and pressure drop, guides airflow uniformly and smoothly, which plays an important role in improving system efficiency.
The ability to independently open and close each piece is a major advantage in system maintenance and repairs. If service, route changes, or access to the duct interior is required, the flange bolts can be loosened and the piece removed without the need to dismantle other parts of the system. The use of galvanized sheet with appropriate thickness guarantees resistance to corrosion and rust, increasing the useful lifespan of the connection.

Specialized Applications
Kian Fan's flanged connections have widespread applications in large industrial and commercial projects. In industrial ventilation systems where air pressure is high and ducts are exposed to vibration and impact, these connections are essential due to their high strength. In large-diameter ducts used in sheds, factories, and ventilation tunnels, flanges are the main providers of structural strength.
Also, in dust collection systems and heavy particle systems requiring strong suction, flanged connections offer reliable performance. In projects where frequent access for duct cleaning or inspection is required, the easy disassembly capability of these connections is very valuable. This product is also used in compressed air production lines and heavy industrial exhaust systems.

Conclusion
The flanged connections of Kian Fan Industrial Production Group, relying on high-quality materials, high machining precision, and resistant design, have established a new standard in industrial duct connections. Choosing this product guarantees safety, long-term durability, and ease of maintenance for complex ventilation systems.
