ASTM A312 TP304 Studded Finned Tube with 11Cr Fins for Oil and Gas Industry

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:

• Enhanced Heat Transfer: the studded design increases the surface area and promotes turbulence, leading to better heat transfer compared to smooth tubes.
• High-Temperature Performance: the combination of TP304 stainless steel and 11Cr fins ensures excellent performance in high-temperature environments.
• Corrosion Resistance: both the base tube (TP304) and the fins (11Cr) offer strong resistance to oxidation and corrosion, making the tube suitable for harsh environments.
• Durability: the robust construction and material properties ensure long-term reliability in demanding applications.

Comparison with Other Finned Tubes

Fins: 11Cr (11% Chromium)

The fins are made of a material containing 11% Chromium, which provides good oxidation resistance and high-temperature strength.

11Cr Fins Properties:

1. High resistance to oxidation and scaling at elevated temperatures.
2. Suitable for use in environments with high sulfur content or other corrosive elements.
