Product Description
Aluminum Embedded Fin Tube Overview
DELLOK Aluminum Embedded Fin Tubes feature aluminum fin strips mechanically embedded into the tube wall through a precision-controlled process. This creates a strong mechanical bond that withstands vibration and continuous thermal cycling up to 400°C, making them ideal for high-temperature industrial applications.
Manufacturing Process
The G fin tube manufacturing involves forming a helical groove in the base tube, winding the fin into the groove under tension, and backfilling the displaced material to securely lock the fin root. This process ensures excellent heat transfer performance and high fin stability.
Key Advantages
- High fin stability and excellent heat transfer efficiency
- Operating temperature capability up to 450°C
- Secure fin-to-tube bond prevents unwinding even when partially uprooted
- Optimal effectiveness-to-cost ratio for industrial applications

Frequently Asked Questions
What is a fin tube?
Finned tubes are the main components of heat exchangers. They feature external fins that increase the contact area with outside fluid, enhancing heat exchange between internal and external fluids.
Where are G Fin Tubes used?
G Fin Tubes are primarily used in air fin coolers and air-cooled radiators for applications with higher temperature requirements. They serve industries including chemical plants, refineries, gas processing, steel plants, power generation, and fertilizer manufacturing.
How is quality ensured?
Quality control includes raw material inspection, production monitoring, water pressure testing, and strength testing. Third-party verification is available, with mill test certifications provided for all materials.
