ASTM A335 P9 High-Frequency Welded Studded Finned Tubes – High-Efficiency Heat Transfer for Industrial Heaters

ASTM A335 P9 High-Frequency Welded Studded Finned Tubes – High-Efficiency Heat Transfer for Industrial Heaters

Material & Design:​​

• ​​Base Tube:​​ ASTM A335 P9 alloy steel (high-temperature and corrosion-resistant).
• ​​Fin Type:​​ Studded (spike fins for turbulent flow and 25%+ higher heat transfer vs. smooth fins).
• ​​Length:​​ 12 meters (customizable).

​​Key Advantages:​​

• ​​Superior Heat Transfer​​: Studded fins disrupt boundary layers, maximizing thermal efficiency.
• ​​Robust Welding​​: High-frequency welding ensures 95%+ weld ratio and minimal contact resistance.
• ​​Mechanical Strength​​: Tensile strength ≥415 MPa, yield strength ≥205 MPa (suitable for high-pressure systems).
• ​​High-Temperature Resistance​​: Operates up to 650°C (ideal for heaters and boilers).

​​Technical Data:​​

​​Applications:​​

• ​​Industrial Heaters​​: Efficient heat exchange in petrochemical and power plants.
• ​​Boilers & Heat Recovery​​: Enhanced durability in high-temperature environments.
• ​​Process Heating​​: Oil refineries, chemical processing, and HVAC systems.

​​FAQ:​​
​​Q: Can studded fins reduce fouling?​​
A: Yes, the turbulent flow minimizes ash/sediment buildup.

​​Q: Do you offer anti-corrosion coatings?​​
A: Yes, options include hot-dip galvanizing or aluminizing.
