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.

The advantages of HFW (High Frequency Welding) Helical Serrated finned tubes include:

1. Improved heat transfer efficiency: The serrations on the fins help to disrupt the boundary layer and increase turbulence, which improves heat transfer efficiency.

2. Lower pressure drop: The serrations also reduce the pressure drop across the finned tube, which can result in energy savings and improved system performance.

3. 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.

4. 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.

5. 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.

6. 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);
