GOST9941-2022 TP321 Stainless Steel U Bend Corrugated Fin Tube for Air Cooler
YUHONG'S Low Finned Tubes are a type of finned tube characterized by a continuous external fin, helically wound around the base tube with a relatively low height. The key features of low finned tubes are as follows:
Increased Heat Transfer: The external fins of the low finned tube significantly augment heat transfer, facilitating efficient heat exchange between the fluid inside the tube and the surrounding environment.
Compact Design: Low finned tubes boast a compact design and offer superior heat transfer capabilities compared to plain tubes, leading to smaller equipment sizes and a reduced overall footprint.
Reduced Material Costs: By using low finned tubes, less material is required to achieve the same level of heat transfer performance, potentially lowering manufacturing costs.
Corrosion Resistance: Low finned tubes are commonly crafted from corrosion-resistant materials such as copper or stainless steel, prolonging the tube's lifespan and decreasing maintenance expenses.
Increased Efficiency: Thanks to the enhanced heat transfer from the external fin, low finned tubes can operate at higher efficiency and lower costs compared to plain tubes.

Characteristics of U Bending Low Finned Tubes
Enhanced Heat Transfer Efficiency: The design of U bending low finned tubes facilitates efficient heat exchange between the fluid flowing inside the tubes and the surrounding air, maximizing the available surface area for heat transfer.
Compact Design: The compact design achieved through the use of U-shaped bends makes these tubes well-suited for applications requiring a considerable surface area in confined spaces.
Flexibility: U bending low finned tubes can be manufactured using various materials such as copper, aluminum, stainless steel, or carbon steel to accommodate different fluid properties and operating conditions.
Customizable Fin Designs: The geometric shape (simple, serrated, wavy, etc.) and spacing of the fins attached to the tubes can be altered to maximize heat transfer performance according to specific application needs.
Corrosion Resistance: These tubes exhibit excellent corrosion resistance based on the chosen construction materials, ensuring durability and prolonged lifespan in demanding operational environments.
Enhanced Mechanical Performance: The stable structure of these tubes, stemming from the U-shaped bends, reduces the likelihood of deformation or damage during handling, installation, and use.
