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:​

​Parameter​ ​Value​
​Base Material​ ASTM A335 P9 (Cr-Mo alloy)
​Fin Height​ 10–20mm (standard)
​Max Temperature​ 650°C
​Pressure Rating​ 150+ MPa (welded joints)

​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.
