I. Project Background
A food processing plant needed to upgrade its drying production line and required heat exchange equipment that was highly efficient, corrosion-resistant, and lightweight. After extensive consideration, they ultimately chose extruded aluminum fin tubes as the core heat exchange component.
II. Material Selection for Extruded Fin Tubes
Base Tube Material: 6063-T5 aluminum alloy, which offers high strength, corrosion resistance, and excellent processability, making it suitable for food processing environments.
Fin Material: Extruded pure aluminum, 0.8mm thick, with an anodized surface for enhanced corrosion resistance.
Process Advantages: The mechanical extrusion process ensures a tight, gap-free bond between the fins and the base tube, resulting in low thermal resistance and over 30% increased heat transfer efficiency.
III. Custom Extruded Fin Tube Specifications
Base Tube Parameters:
Outer Diameter: 25mm (to meet production line space constraints)
Wall Thickness: 1.5mm (to meet pressure requirements)
Length: 6 meters (customizable as a single tube to reduce connection points)
Fin Parameters:
Height: 12mm (to optimize airflow distribution)
Pitch: 3.5mm (to balance air resistance and heat transfer efficiency)
Arrangement: Spiral (to enhance turbulence)
Special Requirements:
Surface sandblasting to improve coating adhesion;
Flanges are provided at both ends for easy installation.
IV. Extruded Fin Tube Production Quantity
Total Required Quantity: 120 tubes (6 meters each, total length 720 meters)
Extruded Fin Tube Production Lead Time:
Mold Making: 3 days
Extrusion Molding: 5 days
Surface Treatment: 2 days
Quality Inspection and Packaging: 1 day
Total Delivery Lead Time: 11 days
V. Extruded Fin Tube Shipping Process
Extruded Fin Tube Packaging:
Individual tubes are wrapped with anti-rust film to prevent scratches during transportation;
Teens are packed in wooden boxes of 10 to prevent deformation;
Boxes are marked with “Upward” and “Fragile” signs.
Extruded Fin Tube Arrival Inspection:
Visual inspection will be completed within 48 hours of receipt;
5% of the tubes will be randomly sampled for pressure testing (1.5 times the working pressure, maintained for 30 minutes with no leaks);
A receipt will be signed upon successful inspection.
VI. Extruded Fin Tube Project Achievements
Performance Improvements:
Drying efficiency increased by 25%, energy consumption reduced by 18%;
Equipment operational stability significantly enhanced, with a 40% decrease in failure rates.
Customer Feedback on Extruded Fin Tubes:
