Material Specifications
Base Pipe (ASTM A335 P9):
Chromium-molybdenum (Cr-Mo) alloy steel with good high-temperature strength and corrosion resistance.
Composition: ~9% Cr, ~1% Mo, balanced with Fe.
Common applications: Power plants, refineries, high-temperature/pressure services (up to ~650°C/1200°F).
Fin Tube Construction
Performance Considerations
Thermal Conductivity: CS fins have lower heat transfer efficiency than aluminum fins but are stronger.
Temperature Limits:
P9 Pipe: Up to 650°C (1200°F).
CS Fins: Max ~400°C (750°F); beyond this, oxidation/scaling occurs.
Corrosion Resistance:
P9 resists oxidation/sulfidation; CS fins may need coatings (e.g., galvanizing, aluminizing) in corrosive environments.
Applications:
- Heat Exchangers: Boilers, economizers, air heaters.
- Process Industries: Refineries, petrochemical plants (for high-temperature gas/liquid streams).
- Power Generation: Waste heat recovery systems.
