High-Frequency Welded Serrated Finned Tubes Base Tube: ASTM A335 P11 | Fins: Aluminum Alloy GR.11


1. Product Overview


High-frequency welded serrated finned tubes combine ASTM A335 P11 chromium-molybdenum alloy steel base tubes with aluminum alloy GR.11 fins via advanced HFW technology. Designed for extreme conditions (≤600°C), they deliver 30%+ higher thermal efficiency than smooth tubes.


2. Material Composition (ASTM-Compliant)


Table: Chemical Properties


Component Base Tube (A335 P11) Fins (GR.11)
Carbon (C) 0.05-0.15% ≤0.15%
Silicon (Si) 0.50-1.00% 0.50-1.50%
Manganese (Mn) 0.30-0.60% ≤0.05%
Chromium (Cr) 1.00-1.50% -
Molybdenum (Mo) 0.44-0.65% -
Aluminum (Al) - ≥98.5%
Iron (Fe) Balance ≤0.7%



Key Material Advantages:


  • P11 Base Tube: High creep strength (60ksi yield) & oxidation resistance.


  • GR.11 Fins: Anti-corrosion (salt spray >1,000hrs), thermal conductivity 200W/m·K.


3. Structure & Manufacturing Process


  • Base Tube: Seamless, OD 15.88-50.8mm, Thickness 2.0-4.5mm


  • Fins: Serrated edge (enhances turbulence), Height 12-20mm, Thickness 0.3-0.5mm


  • Embedding Process:

HFW Technology: Fin-to-base bond strength >100MPa (per ASTM E8)


Helical Pitch: 3-10 fins/inch (customizable)


100% Weld Penetration: Ensures zero thermal contact resistance


4. Precision Tolerances


Table: Dimensional Standards (ASME B36.10)


Parameter Tolerance
Base Tube OD ±0.10mm
Fin Height ±0.15mm
Fin Pitch ±0.2mm
Straightness ≤1.5mm/m


5. Performance Advantages


  • Heat Transfer: 8-12x surface area expansion vs. bare tubes


  • Fouling Resistance: Serrated fins disrupt boundary layers


  • Pressure Integrity: P11 base tube rated for 15MPa @ 450°C


  • Corrosion Protection: GR.11 forms Al₂O₃ protective layer


6. Application Industries


Industry Use Case Examples
Power Generation HRSGs, Air Preheaters, Economizers
Petrochemical Hydrocracker Feed Heaters, Reformers
Waste Heat Recovery Flue Gas Condensers (acid dew point >140°C)
Marine Exhaust Gas Boilers (saltwater corrosion resistance)


7. Why Choose Our Finned Tubes?


  • Certified Quality: EN 10204 3.1, ASME Section II, ISO 9001:2015


  • Custom Engineering: Fin density/height tailored to fluid properties (gas/oil/steam)


  • Proven Longevity: >60,000 service hours in refineries (API 530 compliant)


  • Global Supply: 500+ tons/month capacity, lead time ≤30 days
