Introduction and Technical Structure

In many industrial processes and heat generation systems, transferring air at very high temperatures requires pipes that ordinary materials cannot withstand. Kian Fan Industrial Production Group has provided a reliable and standard solution for these critical conditions by producing the high temperature (refractory) flexible duct. The structure of this product is made of the most advanced thermal insulation materials: the inner and outer layers are made of high-quality fiberglass fabric coated with a layer of silicone. As a heat-resistant polymer, silicone protects the fiberglass from abrasion and moisture and guarantees the product's flame-retardant properties. To increase mechanical strength and prevent collapse, the product body is reinforced with galvanized strips placed inside the structure, maintaining the cylindrical shape.
This product can be manufactured in a diameter range of 10 to 80 centimeters and lengths of 6 to 10 meters, providing the necessary flexibility in designing hot exhaust systems. The operating temperature range of this duct is from -36 to +260 degrees Celsius, enabling it to withstand very severe temperatures for long periods.

Key Features and Advantages

The most important feature of Kian Fan's high temperature duct is its exceptional thermal resistance. The ability to withstand continuous temperatures up to 260 degrees Celsius makes this product essential for connecting to devices such as furnaces, heaters, and dryers. Unlike PVC or aluminum pipes that melt or deform at high temperatures, the silicone refractory duct maintains its structure and properties.
High flexibility despite the reinforced structure allows for installation in complex paths and around hot equipment. Resistance to collapse (Shrink Resistance) resulting from galvanized strips ensures that the duct does not contract under strong suction or hot airflow, keeping the air path open. The strong metallic reinforcing structure also creates high tensile strength against pulling and the product's own weight. The lightweight of this duct compared to heavy metal pipes makes installation and repairs much easier.

Specialized Applications

Kian Fan's high temperature ducts have vital applications in various industries dealing with heat. In systems for exhausting high-temperature air and gaseous vapors, such as exhausts for industrial furnaces, metal melting, and baking furnaces, this product acts as the outlet artery. In the chemical and petrochemical industries for exhausting hot and corrosive vapors, it performs safely due to the resistance of silicone and fiberglass.
In rubber and plastic factories where extrusion processes generate a lot of heat, this duct is used for local ventilation. Also, in ventilation systems for large industrial kitchens, bakeries, and metalworking workshops where the exhaust air temperature is very high, the refractory duct is the best option for safely transferring hot air out of the building. This product is also used in fire prevention systems and mobile chimneys.

Conclusion

The high temperature (refractory) flexible duct of Kian Fan Industrial Production Group, relying on fiberglass-silicone structure technology and metal reinforcement, is a safe and stable solution for managing hot air. Choosing this product guarantees increased workplace safety, prevention of accidents caused by pipe melting, and increased lifespan of the ventilation system under harsh thermal conditions.
