Studded Finned Tube ASTM A312 TP304 with 11Cr Fins for Oil and Gas Industry
Studded Finned Tube- This type of heat exchanger tube has studs—raised, round projections—welded or otherwise affixed to its surface, instead of traditional fins or plates. Studded tubes increase the surface area much like finned tubes, thus improving heat transfer efficiency between fluids or between a fluid and the tube's surroundings.
A Studded Finned Tube ASTM A312 TP304 with 11Cr Fins is a specialized type of heat exchanger tube designed for enhanced heat transfer in high-temperature and corrosive environments. It combines the properties of ASTM A312 TP304 stainless steel with 11Cr (11% Chromium) fins to provide excellent performance in demanding applications.
Advantages of Studded Finned Tubes:
Comparison with Other Finned Tubes
| Feature | Studded Finned Tube | Serrated Finned Tube | Helical Finned Tube |
| Fin Design | Studs (cylindrical protrusions) | Serrated (notched or grooved) | Smooth, helical fins |
| Heat Transfer | High (due to turbulence) | High (due to increased surface area) | Moderate |
| Corrosion Resistance | Excellent (11Cr fins + TP304) | Excellent (TP304H) | Good (depends on material) |
| Applications | High-temperature, corrosive environments | High-efficiency heat exchangers | General heat transfer |
Fins: 11Cr (11% Chromium)
The fins are made of a material containing 11% Chromium, which provides good oxidation resistance and high-temperature strength.
