ASTM A210 / ASME SA210 GR. A1 Carbon Steel HFW Serrated Finned Tube
HFW Serrated Finned Tubes short for high frequency welded helical spiral serrated finned tube. The finned tubes are created by wrapping a thin strip of metal around the base tube in a helical pattern and then serrating the fins to increase the surface area for heat transfer.
The serrations disturb the flow of the fluid, which helps to break up the boundary layer. This turbulence improves heat transfer rates, making serrated fin tubes more effective than traditional finned tubes.
Serrated fin tubes can be used in a wide range of applications, including boilers, condensers, and heat exchangers, in various industries such as power generation, oil and gas, and chemical processing.

What's the difference between welded solid finned tubes and welded serrated finned tubes?
The main difference between them is in the design of the fins.
1. Welded solid finned tubes have fins that are solid and continuous along the length of the tube. These fins provide a large surface area for heat transfer, which can improve the efficiency of the heat exchanger. However, the solid fins can also create a higher pressure drop compared to serrated fins.
2. welded serrated finned tubes have fins that are serrated or notched along their length. These serrations help to disrupt the boundary layer and improve heat transfer efficiency. Serrated fins can also provide a lower pressure drop compared to solid fins.
The advantages of HFW (High Frequency Welding) Helical Serrated finned tubes include:
Improved heat transfer efficiency: The serrations on the fins help to disrupt the boundary layer and increase turbulence, which improves heat transfer efficiency.
Lower pressure drop: The serrations also reduce the pressure drop across the finned tube, which can result in energy savings and improved system performance.
Durable construction: The HFW welding process creates a strong and durable bond between the fins and the base tube, which can withstand high temperatures and pressures.
Versatility: HFW Helical Serrated finned tubes can be used in a variety of applications, including power generation, chemical processing, and HVAC, due to their high efficiency and durability.
Cost-Effectiveness
The efficient heat transfer capabilities reduce the overall size and weight of heat exchangers, potentially lowering material and installation costs. This can lead to significant savings in both initial expenditure and operating costs.
Weld Integrity
The High-Frequency Welding (HFW) process used in manufacturing these fin tubes ensures strong and reliable welds, reducing the risk of failure during operation and enhancing overall tube longevity.
Applications
The common application fields are:
1. Heat exchangers units for power plant(electric, nuclear, thermal and geothermal power plants);
2. High corrosive systems (condensers, evaporators, sea water desalinations, fertilizing, urea systems, ammonia, gas, corrosive acids);
3. The petroleum, chemical and petrochemical industries;
4. The food processing and refrigeration industries;
5. Natural gas treatment;
