Description
Carbon Steel Low Fin Tube For Oil Coolers And Condensers
Carbon Steel Low Fin Tube Overview

Low fin tubes (also called integral fin tubes) are used in heat exchangers, boilers, and condensers to enhance heat transfer efficiency. Their strength depends on material properties, fin geometry, and manufacturing processes.

Material Strength Properties
Property ASTM A179 ASTM A192 ASTM A210
Tensile Strength ≥325 MPa ≥325 MPa ≥415 MPa
Yield Strength ≥180 MPa ≥180 MPa ≥255 MPa
Elongation (%) ≥35% ≥35% ≥30%
Hardness (HB) ≤72 HRB ≤77 HRB ≤79 HRB
Material Applications:
• A179: Best for low-pressure heat exchangers
• A192: Higher pressure applications (boilers)
• A210 (Grade A1): Higher strength for power plants
Fin Geometry & Structural Impact
Parameter Typical Range Effect on Strength
Fin Height 0.8-1.5 mm ↑ Height → ↓ Burst Pressure
Fin Pitch 19-40 fins/inch Denser fins → Slightly weaker
Base Wall Thickness 1.2-3.0 mm Thicker → Higher pressure rating

Burst Pressure: Typically 20-30% lower than smooth tubes due to fin formation.
Collapse Strength: Fins add rigidity but reduce internal pressure resistance.

Performance Comparison: Low Fin vs. Smooth Tubes
Property Low Fin Tube Smooth Tube
Tensile Strength Similar Similar
Burst Pressure ~70-80% of smooth 100% (reference)
Fatigue Resistance Slightly lower Higher
Corrosion Resistance Similar (but fins trap deposits) Better for clean fluids
Recommended Applications
✓ Heat Exchangers (oil coolers, condensers)
✓ Boiler Economizers (improved heat transfer)
✓ Low-Pressure Steam Systems
Usage Limitations
✗ High-Pressure Steam (>1000 psi)
✗ Highly Corrosive Fluids (fins trap deposits)
✗ High-Vibration Environments (risk of fin fatigue)
Key Takeaways
  • Strength approximately 70-90% of smooth tubes (depends on fin design)
  • Optimal for heat transfer efficiency, not extreme pressure applications
  • Material selection (A179/A192/A210) significantly affects performance
