Our Core Manufacturing Capabilities
As a specialized industrial finned tubes manufacturer, Datang Finned Tube offers a diverse range of processing technologies to suit various industrial applications:
1. High-Frequency Welded (HFW) Finned Tubes
Our HFW finned tubes feature a continuous helical fin welded to the base tube using high-frequency electric resistance. This creates a strong, homogeneous bond that is perfect for high-temperature applications like boiler economizers and waste heat recovery units (WHRU).
Characteristics: Achieves 90% to 100% weld penetration, making it highly resistant to vibration and high-pressure cleaning.
2. Extruded Bimetallic Fin Tubes
For projects requiring excellent atmospheric corrosion resistance, Datang Finned Tube provides premium extruded fin tubes. The aluminum fin is cold-extruded from a muff tube over the base pipe, ensuring zero contact thermal resistance and a high degree of protection for the inner tube.
Characteristics: Superior corrosion protection. The base tube is completely isolated from the atmosphere, making it immune to external corrosion.
3. Precision Laser Welded Finned Tubes
Representing the pinnacle of finning technology, our laser welded fin tubes offer a 100% welding bond with a minimal heat-affected zone. This is the preferred choice for high-end industrial cooling systems where mechanical strength and thermal performance cannot be compromised.
Characteristics: Features a minimal Heat Affected Zone (HAZ), preventing thermal distortion in thin-walled or dissimilar metal tubes.
4.Embedded Fin Tubes (G-Type)
Fins are mechanically locked into pre-cut grooves, ensuring stable heat transfer coefficients even during extreme high-temperature cycles up to 400°C.
5.H-Type Finned Tubes
A special structural form where fins are distributed symmetrically in an “H” shape. This design not only increases the heating surface but also creates strong turbulence as flue gas passes through, improving heat transfer efficiency while offering a self-cleaning function to reduce ash accumulation. Datang Finned Tube’s H-type finned tubes are ideal for waste heat recovery in waste incineration and steel sintering machines.

Advanced Geometric Configurations
Recent research highlights that geometric modification is more effective than simply increasing fin density.
-
Symmetrically Inclined Annular Fins: Novel designs using 45° inclination angles have shown a 22.76% to 31.22% increase in convective heat transfer coefficients compared to traditional smooth tubes.
-
Wavy & Louvered Fins: Wavy configurations direct airflow through serpentine channels to improve mixing; adding “louvers” or vortex generators can further reduce thermal resistance by up to 18% .
-
Elliptical vs. Circular: Elliptical fins are increasingly used to minimize pressure drop and entropy generation, while circular fins remain the standard for maximizing heat transfer at the entrance region of tube bundles.
Diverse Industrial Applications
Products from Datang Finned Tube are proven across multiple critical sectors:
-

Industrial Finned Tubes Application
The advantages of greenhouse hot-dip galvanized spiral finned tubes are gradually becoming apparent in agricultural applications. Compared to traditional heating equipment, their unique spiral fin structure significantly increases the heat dissipation area. Combined with the corrosion resistance provided by the hot-dip galvanizing process, these tubes demonstrate remarkable durability in the high-temperature and high-humidity greenhouse environment.
Finned tubes for heat exchangers are essential components designed to enhance thermal efficiency by significantly increasing the external surface area of a base tube. At Datang Finned Tube, we manufacture these specialized tubes to facilitate superior heat transfer between fluids and gases, making them indispensable for industrial cooling and heating applications. By integrating advanced manufacturing techniques like high-frequency welding and extrusion, we ensure our industrial finned tubes meet the rigorous demands of power plants, refineries, and petrochemical facilities worldwide.
Finned tubes for air coolers are the critical heat transfer elements in air-cooled heat exchangers (ACHE), where ambient air is used to cool process fluids. At Datang Finned Tube, we specialize in providing high-performance industrial finned tubes that bridge the gap between low air-side heat transfer coefficients and high tube-side efficiency. By maximizing the external cooling surface, our products ensure optimal thermal performance even in harsh desert or offshore environments
