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.
