Datang’s Stainless Steel Low Fin Tube is specifically designed to enhance heat transfer efficiency by increasing the external surface area without enlarging the overall tube diameter.
These tubes are widely used in air-cooled heat exchangers, condensers, chillers, and evaporators across HVAC, power generation, petrochemical, and refrigeration industries. Made from high-grade stainless steel, they offer excellent corrosion resistance, mechanical durability, and thermal conductivity even under harsh operating conditions.
The integrally formed low fins ensure compact design, longer service life, and reduced fouling. Custom fin height, pitch, and base tube materials are available to match your precise technical requirements.

Stainless Steel Low-Fin Tube Material Selection Guide
| Operating Condition | Recommended Material | Key Characteristics |
|---|---|---|
| Weak Corrosion, Medium-Low Temperature (≤600℃) | 304 Stainless Steel | Good oxidation resistance, resistant to weak acids and alkalis, cost-effective. |
| Strong Corrosion, Chloride-Containing Media | 316L Stainless Steel | Excellent resistance to pitting corrosion (e.g., seawater), temperature resistance ≤800℃. |
| High Temperature, No Strong Corrosion | 321 Stainless Steel | High-temperature resistance, prevents intergranular corrosion. |
| Very High Pressure/Corrosion | Duplex Stainless Steel | Resists stress corrosion cracking. |

Stainless Steel Low Fin Tube Features
• Enhanced external surface area,the finned structure can increase the heat transfer area, and the thermal efficiency is higher than that of ordinary bare tubes.
• Excellent corrosion and heat resistance,304 stainless steel is suitable for general corrosive environments, while 316L is more suitable for highly corrosive or high-temperature environments.
• Compact design, space saving,the fins and base tube are integrally formed, resulting in low contact thermal resistance and stable operation.
• Long service life, minimal maintenance
