Introduction and Technical Structure

In industries dealing with the transfer of abrasive materials and suspended particles, choosing durable and resistant transfer pipes is of high importance. Kian Fan Industrial Production Group, understanding this vital need, has undertaken the production of PU (Polyurethane) flexible ducts, which are symbols of strength and longevity in air and material transfer systems. The structure of this product consists of a spiral tube made of soft and highly resistant polyurethane that is reinforced along the body with a steel spring. This intelligent combination creates unparalleled structural strength against external and tensile pressures while maintaining the necessary flexibility for installation in complex paths.
This product is manufactured in a diameter range of 5 to 25 centimeters and in standard 6-meter lengths, covering the needs of various small and medium projects. One of the distinct technical features of Kian Fan's PU flexible ducts is their operating temperature range. This product has the ability to perform in a wide temperature range of -40 to +90 degrees Celsius, making its use possible in cold climates as well as industries that generate heat.

Key Features and Advantages

The most important feature that distinguishes PU flexible ducts from other products is their extremely high resistance to abrasion (Abrasion Resistance). The polyurethane body of this product resists continuous friction from heavy and sharp particles such as gravel, wood chips, and plastic granules and does not suffer from rapid wear. This feature, along with high resistance to tearing, drastically reduces replacement and repair costs.
High flexibility and favorable tensile strength facilitate the installation of these ducts and enable them to withstand stretching caused by the weight of materials or the movement of machines. Considering the diversity of applications, Kian Fan Industrial Group produces this product with different spring and body thicknesses for light and heavy applications so that customers can select the best option based on pressure intensity and the type of material transfer.

Specialized Applications

Kian Fan's PU flexible ducts have widespread applications in various industries, but their specialty lies in lines for transferring abrasive materials. In woodworking workshops and the timber industry, where the production of wood particles and dust is intense, these ducts act as vital arteries of suction systems and have a long lifespan due to their resistance to the sharpness of wood chips.
In the plastics and granule production industries, this product is used for transferring raw materials and recycling powders. Also, in industrial vacuum systems and central suction units used for cleaning factories and sheds, PU flexible ducts are the best option for connecting suction nozzles to the main duct due to their flexibility and durability. In addition to heavy industrial applications, this product is also used in residential and commercial ventilation in cases where higher mechanical resistance is required compared to ordinary PVC.

Conclusion

The PU flexible ducts of Kian Fan Industrial Production Group, focusing on quality and durability, offer an economic and stable solution for managing the transfer of corrosive and abrasive materials. Choosing this product guarantees reducing downtime caused by pipe failures and increasing the overall productivity of ventilation and material transfer systems.
