ASTM A312 TP304H Stainless Steel HFW Finned Tube Spiral Serrated Fin Tube
HFW Helical finned Tubes are manufactured in both Solid finned type and Serrated type. 304H stainless steel tubes are a high-temperature variant of 304 stainless steel, known for its excellent corrosion resistance and mechanical properties. ASTM A312 TP304H stainless steel HFW finned tubes can enhance the heat performance, which are indeed designed to optimize heat transfer in various applications.
1. Solid Finned Tubes: Feature continuous solid fins wrapped in a helical pattern around the tube.
Advantages:
Efficient Heat Transfer: The solid fins provide a larger surface area for heat exchange.
Durability: Robust structure suitable for high-pressure applications.
2. Serrated Finned Tubes: Have fins with serrated edges, which increase turbulence in the fluid flow.
Advantages:
Enhanced Thermal Performance: Increases turbulence, improving heat transfer efficiency.
Lower Pressure Drop: The serrations help in reducing flow resistance compared to solid fins.
