나는. 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.
2 세. Material Selection for Extruded Fin Tubes
베이스 튜브 재질: 6063-T5 aluminum alloy, which offers high strength, 내식성, and excellent processability, making it suitable for food processing environments.
핀 재질: 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.
3세. Custom Extruded Fin Tube Specifications
Base Tube Parameters:
Outer Diameter: 25밀리미터 (to meet production line space constraints)
Wall Thickness: 1.5밀리미터 (to meet pressure requirements)
Length: 6 미터 (customizable as a single tube to reduce connection points)
Fin Parameters:
Height: 12밀리미터 (to optimize airflow distribution)
Pitch: 3.5밀리미터 (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.
정맥. Extruded Fin Tube Production Quantity
Total Required Quantity: 120 tubes (6 meters each, total length 720 미터)
Extruded Fin Tube Production Lead Time:
Mold Making: 3 days
Extrusion Molding: 5 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” 그리고 “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.
