Serrated FinTube , ASTM A335 P9 Alloy Steel Pipe with 11Cr Fin for Heat Exchanger
Serrated finned tubes feature fins that are not smooth, but rather have a sawtooth or serrated profile. They are arranged in a helical pattern around the tube, allowing for more efficient heat exchange, especially in applications involving gas or liquid. High-Frequency welding method is used to attach the fins to the tube without the need for additional materials, enhancing heat transfer by creating turbulence in fluid flow, resulting in a higher heat transfer coefficient while also reducing flow resistance. Made from materials like carbon steel, stainless steel, or alloy steel, which depend on different using environments.

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.
Applications
These finned tubes find application in various industries where efficient heat transfer is crucial, such as in power plants, chemical processing plants, HVAC systems, refrigeration, and many other heat exchanger applications.
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;
