ASTM A312 TP347 Stainless Steel Tube HFW Serrated Finned Tube
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.

Difference between welded solid finned tubes and welded serrated finned tubes
(1)Welded finned tubes have ribs that are continuous and constant along the length of the tube. These fins provide a large heat transfer surface area, which can improve the performance of the heat exchanger. However, solid fins can also result in a greater 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)
The common application fields
1. heat exchangers for power plants (electric, nuclear, thermal and geothermal power plants);
2. highly corrosive systems (condensers, evaporators, seawater desalination, fertilisation, urea systems, ammonia, gas, corrosive acids);
3. petroleum, chemical and petrochemical industries;
4. food and refrigeration industry;
5. natural gas treatment;
