High Light Serrated Fin Tubes ASTM A335 P221Cr13 Finned Tubes for heat exchangersASTM A335 P22 serrated fin tubes
Serrated Fin Tubes (ASTM A335 P22 / 1Cr13)
Overview

Our Serrated Fin Tubes are engineered for maximum heat transfer efficiency in industrial boilers, superheaters, and heat exchangers. The base tube, manufactured from ASTM A335 P22 alloy steel, ensures high-temperature strength and durability, while the fins made of 1Cr13 stainless steel provide excellent corrosion resistance and maintain structural integrity under prolonged high-temperature operation. The serrated fin design enhances turbulence across the gas flow, improving thermal efficiency compared with conventional straight fins.

Applications:
  • Industrial boiler economizers and superheaters
  • Air-cooled heat exchangers
  • Petrochemical and refinery process heat recovery
  • Waste heat recovery boilers (WHRB)
  • Power plants and thermal energy systems
Standard Size Ranges
Parameter Typical Range
Base Tube OD 15.88 mm – 219 mm
Tube Wall Thickness 2.77 mm – 10 mm
Fin Height 8 mm – 25 mm
Fin Thickness 0.8 mm – 2.0 mm
Fin Pitch 3.5 mm – 10 mm
Finned OD Up to 150 mm
Tube Length Up to 18 meters
Fin Density Customizable per thermal design

Custom dimensions are available to meet project-specific requirements.

Chemical Composition
Base Tube – ASTM A335 P22
Element Composition (%)
Carbon (C) 0.05 – 0.15
Manganese (Mn) 0.30 – 0.60
Phosphorus (P) ≤ 0.025
Sulfur (S) ≤ 0.025
Silicon (Si) ≤ 0.50
Chromium (Cr) 1.90 – 2.60
Molybdenum (Mo) 0.87 – 1.13
Fin Material – 1Cr13 Stainless Steel
Element Composition (%)
Carbon (C) ≤ 0.12
Chromium (Cr) 12 – 14
Manganese (Mn) ≤ 1.00
Silicon (Si) ≤ 1.00
Phosphorus (P) ≤ 0.04
Sulfur (S) ≤ 0.03

The combination ensures high creep strength, oxidation resistance, and corrosion protection in high-temperature flue gas conditions.

Inspection & Quality Assurance

All serrated fin tubes undergo rigorous inspection to ensure compliance with industrial standards:

  • Raw Material Verification
    • Mill Test Certificate (MTC) for both tube and fins
    • Chemical composition verification
  • Dimensional Inspection
    • Tube OD, wall thickness, and length
    • Fin height, thickness, pitch, and overall finned OD
    • Straightness and alignment checks
  • Weld & Fin Inspection
    • Visual weld inspection for fin attachment
    • Ultrasonic Testing (UT) of base tube
    • Eddy Current Testing (ECT) for fin integrity
  • Pressure Testing (Optional)
    • Hydrostatic or pneumatic testing upon customer request
  • Documentation Provided
    • Material Test Certificate (MTC)
    • Dimensional inspection report
    • NDT inspection report
    • Heat treatment records (if applicable)
Advantages
  • Enhanced heat transfer due to serrated fin geometry
  • High-temperature strength from ASTM A335 P22 base tube
  • Excellent corrosion resistance from 1Cr13 fins
  • Customizable dimensions for project-specific designs
  • Long-term operational reliability in industrial boilers and heat exchangers
  • Reduced maintenance and fouling due to interrupted fin design
