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.
