• Typically made from carbon steel (e.g., ASTM A106 Grade B, ASTM A53 Grade B) or alloy steel (e.g., ASTM A335 P11, P22 for high-temperature service).
• Seamless or welded, depending on pressure/temperature requirements.

• Material: Carbon steel, stainless steel (304, 316), or aluminum (for corrosion resistance).
• Spiral Fin Design: Fins are helically wrapped around the pipe, welded or bonded to the outer surface. This spiral pattern ensures uniform heat distribution and minimizes airflow resistance.

ASTM Standards & Specifications

While no single ASTM standard exclusively covers fin pipes, key references include:

 

• Base Pipe:
  • ASTM A106/A106M: Seamless carbon steel for high-temperature service.
  • ASTM A53/A53M: Welded/seamless carbon steel for general use.
  • ASTM A335/A335M: Alloy steel for high-temperature, high-pressure pipelines.
• Fin Materials:
  • ASTM A1011: Hot-rolled carbon steel for fins.
  • ASTM A240: Stainless steel fins (e.g., 304, 316).
• Welding: ASTM A381 (for welding procedures of finned tubes).

Manufacturing of Spiral Fin Pipes

1. Base Pipe Preparation: Cleaned and inspected for defects (e.g., cracks, uneven walls).
2. Fin Forming: Metal strips are rolled into a spiral shape with precise pitch (distance between fins).
3. Bonding:
   • Welded Fins: Continuous or spot-welded to the pipe for high-temperature durability.
   • Extruded/Bonded Fins: Fins are pressed or bonded using adhesives (for low-temperature applications).
4. Surface Treatment: Galvanizing, painting, or coating (e.g., epoxy) to resist corrosion.

 

Applications

• Power Plants: Boiler economizers, air preheaters, and condenser tubes.
• Oil & Gas: Heat exchangers in refineries, gas processing units.
• HVAC: Industrial chillers, radiators, and air conditioning systems.
• Chemical Processing: Cooling towers, process heaters, and waste heat recovery units.
