In April, Datang successfully delivered a batch of 200 extruded fin tubes to a customer in the Philippines.
Under the tropical climate conditions of Southeast Asia, the food processing industry enforces stringent standards for the energy efficiency and hygiene of drying equipment. Our client, a leading food processing equipment manufacturer in the Philippines, recently upgraded their drying production line. The new industrial food drying machinery required high-performance heating elements capable of precise temperature control, robust durability, and superior heat transfer efficiency—ensuring consistent product quality while significantly reducing energy consumption.
After several rounds of technical communication, the Datang Finned Tube engineering team recommended an extruded fin tube solution for the client. Manufactured through a metallurgical bond that tightly integrates aluminum fins with the steel base tube, this process combines the pressure resistance of steel with the superior thermal conductivity of aluminum—making it an ideal choice for food drying, dehydration, and similar applications.
Datang Finned Tube Solution
Based on the client’s thermal calculation and space constraints, Datang Finned Tube custom-engineered 200 pieces of high-efficiency extruded finned tubes with the following precision specifications:
-
Product Process: Extruded Finned Tube
-
Base Tube Material: ASTM SA179 Seamless Carbon Steel Tube (ensuring a smooth inner surface and high pressure resistance)
-
Dimensions & Parameters:
-
Base Tube OD × WT: Φ20 × 3 mm
-
Total Length: 1315 mm
-
Bare Ends: 30 mm at both ends (for ease of welding, installation, and sealing)
-
Fin Height: 11 mm
-
Fin Thickness: 0.5 mm
-
-
Process Advantages: Utilizing advanced aluminum extrusion technology, the aluminum fins are metallurgically bonded with the inner steel tube. This structural integrity eliminates thermal contact resistance and prevents fins from loosening or detaching under long-term high-temperature operation, significantly enhancing heat transfer efficiency.
Why Extruded Finned Tubes from Datang?
For food drying applications in humid climates like the Philippines, Datang’s Extruded Finned Tubes offer distinct advantages:
-
100% Thermal Contact: The aluminum outer tube is mechanically cold-extruded over the ASTM SA179 base tube, creating an airtight, gap-free bond. This eliminates thermal resistance and maximizes heat transfer efficiency.
-
Superior Corrosion Resistance: The extruded aluminum sleeve completely seals the base tube from ambient air, moisture, and vaporized food acids, preventing atmospheric corrosion and extending equipment lifespan.
-
Rugged & Washable: Unlike L-type or KL-type fins, extruded fins are solid and rigid. They can withstand high-pressure water washing during routine hygienic cleaning without fin deformation.
Quality Control & Delivery
-
Dimensional Precision: Every single tube underwent rigorous inspection to guarantee exact overall length, perfectly matching the customer’s existing drying equipment frame. Millimeter-level accuracy was strictly enforced for total length, bare ends, and fin specifications.
-
Material Integrity: Prior to processing, the ASTM SA179 seamless steel tubes were subjected to stringent hydrostatic testing and quality checks, ensuring zero leakage and no risk of corrosion. This guarantees exceptional corrosion resistance and mechanical strength under high-temperature and high-pressure conditions, meeting the stringent standards of food-grade equipment.
-
On-Time Delivery: Delivery was completed 3 days ahead of schedule. All 200 finned tubes were manufactured in strict accordance with drawing requirements, with dimensional tolerances kept to a minimum. The on-site installation achieved a 100% first-time success rate, significantly reducing the customer’s maintenance downtime.
- Packaging: All 200 pieces were securely packed in custom wooden crates to prevent fin damage during maritime transit from our factory to the Philippines.
Customer Testimonial
The 200 units of extruded finned tubes were successfully integrated into the client’s food drying units. Upon commissioning, the drying equipment achieved rapid heat-up times and excellent thermal uniformity. The client expressed great satisfaction with the structural integrity of Datang Finned Tube’s products and our strict adherence to custom specs.
The Philippine customer expressed high recognition of Datang Finned Tube’s professional services: “From technical parameter confirmation to final product delivery, the Datang team demonstrated exceptional professionalism.
