Product Overview

ASTM A335 P22 Helical Solid Finned Tube is a high-performance heat exchanger tube manufactured from seamless ferritic alloy steel. The helical solid fins on its exterior surface significantly increase surface area for enhanced heat transfer efficiency, making it ideal for power generation, petrochemical, and chemical processing applications.

Key Features and Benefits
  • Enhanced Heat Transfer: Helical fins increase surface area for superior thermal performance
  • Compact Design: Achieves higher heat transfer rates without increasing exchanger size
  • Durable Construction: Seamless ferritic alloy steel withstands high-temperature and high-pressure conditions
  • Corrosion Resistance: Excellent resistance to wear and corrosion in demanding environments
Material Specifications
Chemical Composition
  • Carbon (C): 0.05 - 0.15%
  • Manganese (Mn): 0.30 - 0.60%
  • Phosphorus (P): 0.025% max
  • Sulfur (S): 0.025% max
  • Silicon (Si): 0.50 - 1.00%
  • Chromium (Cr): 1.90 - 2.60%
  • Molybdenum (Mo): 0.87 - 1.13%
Mechanical Properties
  • Tensile Strength: 415 MPa (60,200 psi) minimum
  • Yield Strength: 205 MPa (29,800 psi) minimum
  • Elongation: 30% minimum
  • Hardness (HB): 163 maximum
  • Impact Strength: 35J (26 ft-lbf) minimum at -20°C (-4°F)
Industrial Applications
  • Heat Exchangers: Optimizes thermal transfer between fluids with enhanced surface area
  • Chemical Processing: Resists corrosion from aggressive fluids and gases
  • Power Generation: Used in boilers, steam generating tubes, and reheater tubes
  • Petrochemical Industry: Ideal for heat exchangers and condenser tubes
  • Automotive Systems: Improves thermal performance in exhaust systems
