Welded Fin Tubes (Continuously Welded Spiral Fin Tubes)
As the name suggests, Welded Fin Tubes feature spirally wound fins that are continuously welded to the base tube. This process involves winding the fin strip around the tube while simultaneously applying high-frequency welding or laser welding, creating a highly robust bond between the fin and the tube. This ensures maximum durability and heat transfer efficiency.
Key Features:
- Superior Fin-to-Tube Bond: The continuous high-frequency welding process provides the strongest possible connection, making these fin tubes highly resistant to mechanical stresses such as continuous vibrations.
- Exceptional Heat Transfer: The welded bond ensures nearly perfect heat transfer efficiency, making them ideal for high-performance applications.
- High Temperature Tolerance: Suitable for applications requiring high operating temperatures.
Applications:
These fin tubes are widely used in systems that demand high durability and efficiency, such as:
- Radiators
- Air Preheaters
- Waste Heat Recovery Systems
- Boiler Fin Tubes
They are especially favored in industries like:
- Power Plants
- Chemical Processing
- Steel Manufacturing
- Chiller Plants
With their excellent mechanical strength and thermal performance, High Frequency Welded or Laser Welded Fin Tubes are an optimal choice for challenging industrial environments.

Advanced Manufacturing Technology
Laser Welded Spiral Fin Tubes
While traditional methods like high-frequency welding and resistance welding are commonly used to attach stainless steel fins to steel pipes, we highly recommend Laser Welded Spiral Fin Tubes for superior performance and efficiency.
What Sets Laser Welding Apart:
- Advanced Technology: Laser welding utilizes a fully automated process, reducing labor costs and increasing productivity. This state-of-the-art method uses precision laser beams to achieve a solid and durable bond between the fin and the tube.
- Superior Bonding Strength: The laser-welded fins demonstrate excellent tensile strength, ensuring a robust connection that withstands mechanical stresses and vibrations.
- Enhanced Efficiency: Laser welding provides a more efficient manufacturing process compared to traditional methods, resulting in higher quality and more reliable finned tubes.
- Higher Technological Content: Thanks to the fully automatic and mechanized nature of laser welding, the quality of laser-welded spiral finned tubes is superior to that of traditional cooling pipes.
Key Advantages:
- Fully automated laser welding process
- Strong, durable bond with high tensile strength
- Increased efficiency and reduced production costs
- Higher quality and technological content compared to conventional welded tubes
The Laser Welded Spiral Fin Tube is the most advanced option for applications requiring reliable heat transfer and durability, making it an excellent choice for modern industrial cooling systems.
Advantages of Laser Welded Helical Fin Tubes
- Robust Fin Attachment: Utilizing a continuous laser welding machine, the fins are welded firmly to the tube with an automatic winding device, ensuring no missed welds. This results in a highly durable bond between the fins and the tube.
- Superior Weld Strength: The laser welding process fuses the base metals of both the fins and tubes, achieving a weld strength of over 600 MPa, significantly enhancing the overall durability of the finned tubes.
- Precision Welding Technology: Equipped with an automatic finned tube laser welding machine using a servo closed-loop system, this method provides high transmission accuracy and precise welds, leading to consistent and high-quality results.
- Optimized Heat Dissipation: Laser welding allows for a fin spacing as narrow as ≤2.5mm, increasing the heat dissipation area by nearly 50% compared to traditional high-frequency welded tubes, which typically have a fin spacing of ≥4.5mm. This efficient design reduces material usage per unit area, enabling a more compact heater volume and cost savings.

The solid fin configuration is versatile and can be used in almost any heat transfer application. It is particularly well-suited for high-temperature and high-pressure environments with elevated fin-side temperatures.
Key Advantages:
- Enhanced Durability: Solid fins can be manufactured with thicker materials compared to serrated fins, making them ideal for applications involving extremely corrosive or erosive conditions.
- Superior Performance in Harsh Environments: This configuration is the preferred choice for severe service conditions, especially where exposure to fibrous or sticky fluids is common. Solid fins are resistant to fouling and can withstand repeated cleanings without damage.
- Ideal for Demanding Applications: Due to their robustness, solid fins excel in applications that demand high resilience, making them suitable for heat exchangers in challenging industrial processes.
