Elliptical Fin Tube|Elliptical Tube With Rectangular Fins| Hot dipped galvanized oval fin tubes
Introducing our elliptical fin tube, featuring hot-dipped galvanized oval fin tubes. This innovative design incorporates an elliptical tube shape along with an aerodynamic airfoil structure, specifically engineered to reduce airflow resistance on the air side. Compared to traditional round tube types, these fins demonstrate enhanced performance characteristics. The hot-dip galvanization process significantly increases the corrosion resistance of these fins, ensuring longevity and durability in diverse environments. Furthermore, these fin tubes offer a compact solution relative to other designs, boasting remarkable heat transfer efficiency.
What Is Elliptical Fin Tube Or Oval Fin Tube?
Elliptical fin tube also called oval fin tube. Elliptical finned tubes have two parts, one is elliptical tubes and rectangle fins. The elliptical tube can be seamless steel tube or welded oval steel tube. The fins are carbon steel and in rectangular shape. Furthermore the rectangular fin can be with interrupting holes or without interrupting holes.
Elliptical Finned Tube design utilizes an elliptical shaped tube with an efficient air foil shape to minimize airside flow resistance, While these rectangular fins can improved heat transfer performance characteristics compared to round tube types.
The oval finned tube is a specific kind of heat exchanger featuring an oval-shaped base tube with external rectangular fins. Variants of this design include oval rectangular finned tubes, oval-oval finned tubes, oval circular finned tubes, spiral oval flat tubes, and oval H-shaped finned tubes. These oval finned tubes are becoming increasingly favored due to their enhanced efficiency compared to traditional round finned tubes, making them prevalent in sectors like ethylene production and oil refining.
How To Manufacture The Elliptical Fin Tube?
1. Produce seamless or welded oval steel tube;
2. Punched the rectangular fins through mold on steel coils;
3. Automatically fill the fins into elliptical tubes;
4. Hot dip galvanized the finned tubes. The finned tube dipped in melted zinc tanks. The gap between the fin and the core tube is filled completely by zinc.
How About The Elliptical Fin Tube Surface Treatment?
The corrosion resistance of these fins will be very high after being hot dip galvanized. These fin tubes are very compact compared to other types of fin tubes and their heat transfer efficiency is significant. So its also called Hot dipped galvanized elliptical/oval fin tubes.
Quality Control for Square Finned Tube
The quality of Square or Rectangualr H finned tubes is assured by hydrostatic or aerodynamic testing, eddy current testing and tensile testing to verify the mechanical bond between the inner tube and outer fins.
Delivery condition:
Tube ends are square cut, free burrs, internally dried and air blown clean, externally coated with Anti-rust at both ends of elliptical finned tube.

Hot Dipped Galvanized Elliptical Finned Tube By Industy
Elliptical finned tubes are widely used in various industrial fields, including petrochemical, electric power, metallurgy, pharmaceutical and food. In these fields, elliptical finned tubes are often used to cool various process fluids such as circulating water, cooling water and hot oil, and are also suitable for cooling gases such as air and nitrogen. Its high efficiency heat exchange and energy saving and environmental protection characteristics enable the equipment to operate stably in various environments and are easy to install and maintain.
Top Features of Elliptical Finned Tube
Datang offers the widest variety of sizes available for elliptical tube with rectangular fins tube in the industry.Its heat exchange efficiency can reach several times or even dozens of times that of ordinary heat exchangers.
(1) Compared with the round tube finned tube, the Elliptical Finned Tube is easier to achieve a compact arrangement, which reduces the overall volume of the entire heat exchanger, thereby reducing the footprint.
(2) Due to the shape characteristics of the Elliptical Finned Tube, the air-side resistance is small, and the heat transfer coefficient between the fluids increases; the thermal resistance in the tube is relatively small, which increases the heat transfer of the fluid in the tube.
(3) The heat transfer area of the Elliptical Finned Tube is larger than that of the circular tube of the same cross-sectional area, because the heat transfer periphery of the elliptical tube is relatively long under the same cross-sectional area.
(4) Rectangular steel fins are the most commonly used in Elliptical Finned Tubes, which have high strength, and the base tube is not suitable for frost cracking in winter and has a long service life.
(5) Since the Elliptical Finned Tube can be arranged more compactly, the front row tube has a greater impact on the rear row. The fin spacing of the rear row tube can be increased to reduce the flow resistance outside the tube, but the number of tube rows should not be too large.

Hot Dipped Galvanized Elliptical Finned Tube Application

The convection chamber of the heating furnace in the petrochemical industry is used in the elliptical finned tube,which can increase the heat transfer coefficient on the gas side, and the area of the elliptical tube is 2 to 3 times that of the straight tube. Due to the application of Elliptical Finned Tube, in the design of this case, the same radiation intensity can get the same thermal intensity.It uses winding technology, ranging from stable, segmented combination and firm, to surface galvanized and nickel-based brazing, depending on the application. has a high heat transfer efficiency, while the wind side has a small.Compared with the section of the circular tube, the heat transfer coefficient can be increased by 25%, and the air resistance can be reduced by 15%-25%.

Industrial dry heat exchanger, due to its high efficiency heat exchange and corrosion resistance, hot dip galvanized oval fin tubes perform well in industrial dry heat exchangers, can quickly respond to system temperature changes and maintain a stable heat dissipation effect.

The galvanized oval finned tube heat exchanger is a highly efficient heat exchange device specially designed for the food drying process. Its core working principle is to greatly increase the heat exchange area through the special structure of the oval finned tube, thereby improving the heat exchange efficiency. The fin shape of the oval finned tube can increase the heat transfer area of the pipe, making the heat exchange efficiency higher.
