  .
• ​​Length:​​ 12 meters (customizable).

​​Key Advantages:​​
​​Enhanced Heat Transfer​​: Serrated fins disrupt boundary layers, optimizing thermal exchange.
​​Durable Welding​​: High-frequency welding ensures ​​95%+ weld ratio​​ and low contact resistance.
Mechanical Strength​​: Tensile strength ≥415 MPa, yield strength ≥205 MPa (ideal for high-pressure systems).
Corrosion Resistance​​: Chromium-molybdenum alloy (Cr: 1.9–2.6%, Mo: 0.87–1.13%) resists oxidation.

​​Technical Data:​​

​​Applications:​​

• ​​Heat Exchangers & Boilers​​: Efficient energy recovery in power plants.
• ​​Petrochemical​​: Heaters, condensers, and flue gas systems.
• ​​Industrial Drying​​: Food, pharmaceuticals, and textiles.

​​FAQ:​​
​​Q: Can you customize fin density?​​
A: Yes, we tailor fin pitch (3–10 fins/inch) per application needs.

​​Q: What’s the lead time?​​
A: 15–30 days for standard sizes; expedited options available.
