ASME SA312 TP347 HFW Serrated Finned Tube for Fired Heater, High Temp Oxidation Resistance

HFW Serrated Finned Tubes stands for High Frequency Welded Spiral Serrated Finned Tubes. Finned tubes are created by wrapping a thin strip of metal around a base tube in a spiral pattern and then serrating the fins to increase the heat transfer surface area. The serrations also help to disrupt the boundary layer and improve heat transfer efficiency. High-frequency welding is used to join the ribs to the base pipe, creating a strong and durable bond. The resulting ribbed pipe can provide better heat transfer performance compared to smooth pipes, making it ideal for applications where high performance is required.

• Improved heat transfer performance: The serrations on the fins help to disrupt the boundary layer and increase turbulence, which improves heat transfer performance.
• Lower pressure drop: The serrations also reduce the pressure drop across the finned pipe, which can result in energy savings and improved system performance.
• Durable design: the HFW welding process creates a strong and durable connection between the fins and the base pipe, which can withstand high temperatures and pressures.
• Versatile: HFW Helical Serrated finned tubing can be used in a variety of applications, including power generation, chemical processing and HVAC, due to its high performance and durability.
