SA335 P9 Solid Fin Tube Technical Information
What is SA335 P9 Solid Fin Tube?
SA335 P9 is a seamless ferritic alloy-steel pipe (9% Cr, 1% Mo) with integrally welded or extruded fins to enhance heat transfer. It's used in high-temperature/pressure environments like:
  • Boilers
  • Heat exchangers
  • Industrial heaters
Key properties of SA335 P9
  • High-temperature strength (up to ~600°C / 1112°F)
  • Excellent creep & oxidation resistance
  • Good weldability (pre/post-weld heat treatment required)
  • Resistance to sulfidation & thermal fatigue
Common applications
  • Power plants (superheaters, reheaters)
  • Refineries (fired heaters, reformers)
  • Petrochemical (ethylene crackers, heat recovery units)
  • Waste heat boilers (recovering exhaust gas energy)
Advantages of solid fins
  • Higher durability (no risk of fin separation)
  • Better heat transfer (continuous metal bond)
  • Suitable for extreme thermal cycling
Standards compliance
  • Base Tube: ASTM SA335 P9 (seamless pipe)
  • Fin Tube: Complies with ASME B36.10M (dimensions), ASTM A213 T9 (tube equivalent)
  • Testing: Hydrostatic, ultrasonic (UT), eddy current (ET) per ASTM A450
Manufacturing process
  • Base tube: Hot extruded/seamless cold-drawn
  • Solid fins: Machined/welded integrally
  • Extruded fins: Cold-formed from base metal
  • Heat treatment: Normalized & tempered for stress relief
Temperature & pressure limits
  • Max temp: ~600°C (long-term), up to 650°C (short-term)
  • Pressure rating: Varies by wall thickness (e.g., 1000+ psi for typical power plant applications)
Grade Comparison
Grade Cr Content Mo Content Max Temp Key Advantage
P9 9% 1% 600°C Balanced cost/performance
P11 1.25% 0.50% 550°C Better weldability
P22 2.25% 1% 575°C Common in refineries
P91 9% 1% + V,Nb 650°C Superior creep strength
