Here is the professional English translation of the technical documentation for Grooved G-Type Embedded Finned Tubes:
⚙️ I. Grooved G-Type Embedded Finned Tube Core Structure & Working Principle
-
Manufacturing Process
- Helical grooves are precision-machined onto the base tube (carbon steel, stainless steel, copper, etc.), followed by high-tension mechanical inlay of metal strips (aluminum, copper, or stainless steel).
- Fin ends are laser-welded to prevent detachment and maximize thermal contact area.
-
Heat Transfer Mechanism
- Fins expand the surface area (up to 8× that of bare tubes), significantly enhancing heat exchange efficiency.
- Heat conducts from the internal medium through the base tube to fins, dissipating via convection/radiation in gas-liquid or gas-gas applications.
???? II. Grooved G-Type Embedded Finned Tube Key Technical Parameters
| Parameter | Range/Specification | Remarks |
|---|---|---|
| Base Tube Material | Carbon steel/SS/copper/alloy | Wall thickness ≤2mm; pressure ≤32MPa |
| Fin Material | Al 1060/1100, Cu, SS | Thickness: 0.35–0.4mm; height ≤½ tube dia. |
| Operating Temp. | ≤400°C | Stable contact resistance under thermal shock |
| Pull-Out Strength | ≥70N (up to 80N) | Anti-detachment performance standard |
| Fin Pitch Accuracy | ±0.21mm/fin | Ensures airflow uniformity & reduces fouling |
⭐ III. Grooved G-Type Embedded Finned Tube Performance Advantages
- Enhanced Heat Transfer
- Minimal contact resistance; heat transfer coefficient 1–2× higher than bare tubes; surface area expanded 2–30×.
- Corrosion/Fouling Resistance
- Fins shield the base tube (zinc plating optional); fouling sheds automatically via thermal cycling.
- Structural Stability
- High rigidity; maintains performance integrity below 280°C long-term.
- Low Maintenance
- Modular design enables rapid replacement without frequent cleaning.
???? IV. Grooved G-Type Embedded Finned Tube Typical Applications
- Energy & Chemical
- Petrochemical air coolers, power plant boiler economizers (handling 400°C flue gas).
- Industrial Heating
- Spray dryers (starch, protein powder), air heaters, building heating systems.
- Eco-Energy Equipment
- Waste heat recovery, compressor cooling; reduces energy consumption by ≥26% (e.g., low-temp. hot water systems).
⚠️ V. Grooved G-Type Embedded Finned Tube Selection & Usage Guidelines
- Environment Limits: Avoid strong corrosive media (e.g., acidic gases); aluminum fins have limited corrosion resistance.
- Process Optimization: Narrow grooves complicate inlay; control side gap to prevent stress concentration.
- Maintenance: Regularly inspect fin root welds for cracks.
Note: Data synthesized from manufacturer specifications and industry reports; actual performance requires field validation.
