ASME SA249 TP304 AL Extruded T-Type Finned Tubes For Dry Oven Heat Exchange
Yuhong Group, with over a decade of experience in finned tube manufacturing, proudly produces and sells seamless stainless steel, duplex, and nickel tubes. Serving clients in 45 countries with annual sales exceeding 80,000 tons, our tubes are used across mining, power generation, petrochemical, food processing, paper manufacturing, and gas/liquid industries.
Product Overview
Our ASME SA249 TP304 AL extruded finned tubes for heat exchangers offer excellent chemical and mechanical properties, making them ideal for heat transfer processes. They feature high tensile strength, good yield strength, and excellent corrosion resistance, ensuring durability even in demanding operating conditions.
Made from TP304 AL (aluminum) material, these finned tubes are lightweight with high thermal conductivity and corrosion resistance. This makes them perfect for heat exchangers where efficient heat transfer and longevity are critical. Applications include power generation, chemical processing, oil and gas, HVAC systems, air coolers, condensers, evaporators, and other heat exchange equipment.
Key Features
- Extruded fins increase surface area for enhanced heat transfer efficiency
- Tight fin-to-tube contact ensures effective heat transfer and minimizes scaling risk
- Proper installation and sealing required for optimal performance
- Regular inspection and maintenance recommended to detect corrosion or damage
