3. Processing Technology
The production of our ASTM B163 Alloy825 extruded finned tubes adopts advanced extrusion technology. First, the Alloy825 base tube is strictly inspected and processed to ensure its dimensional accuracy and surface quality. Then, the aluminum fins are extruded onto the base tube through a special die. This extrusion process makes the fins and the base tube closely combined, effectively reducing the contact thermal resistance and improving the heat transfer efficiency. After the extrusion is completed, a series of quality inspections are carried out to ensure that the product meets the relevant standards.
4. Performance
- Heat Transfer Performance: Due to the excellent thermal conductivity of aluminum fins and the close combination between fins and base tube through extrusion process, the heat transfer efficiency of the product is significantly higher than that of ordinary finned tubes. It can effectively transfer heat in air cooler heat exchangers, improving the overall operation efficiency of the equipment.
- Corrosion Resistance: The Alloy825 base tube has strong corrosion resistance, which can resist the corrosion of various media such as acid and alkali, ensuring the long-term stable operation of the product in harsh environments.
