Overview:
SA249 TP304 stainless steel extruded fin tubes are integral components used in heat exchangers, particularly in rice mills, due to their excellent thermal efficiency and resistance to corrosion. The SA249 standard ensures high-quality manufacturing processes, offering tubes that can withstand demanding environments.
These fin tubes have an outer layer enhanced with extruded fins, which significantly increase the surface area for heat transfer. Made from TP304 stainless steel, they exhibit robust mechanical properties and excellent resistance to oxidation, making them suitable for high-temperature applications. The material is also non-magnetic and provides good ductility, allowing for easy shaping and fabrication.
In the rice milling industry, effective heat exchange is crucial for processes such as parboiling and drying. The enhanced surface area of fin tubes promotes better heat transfer, optimizing energy consumption and improving overall efficiency of the heat exchanger. This translates to higher productivity and reduced operational costs for rice mills.
Their durability and low maintenance needs are additional advantages, as TP304 stainless steel resists pitting and crevice corrosion, ensuring long lifespans even under constant exposure to moisture and varying temperatures. Furthermore, these fin tubes can be customized in terms of dimensions and fin geometry, catering to specific design requirements of various heat exchanger systems.
Yuhong Group provides a variety of high-quality extruded fin tube. Our products are exported to overseas and have won unanimous praise from customers.
