Product Overview

An extruded finned tube is a type of heat exchanger tube where fins are mechanically bonded to the outer surface of a base tube through an extrusion process. This design significantly increases the tube's surface area, improving heat transfer efficiency in applications involving air or gas cooling/heating.

Manufacturing Process
  • Base Tube Selection: Typically made of carbon steel (e.g., ASTM A179), stainless steel, or other alloys.
  • Fin Material: Common choices include Aluminum 1060 (Al1060) for lightweight and corrosion resistance.
  • Extrusion Process: The pressure and rotation mechanically bond the fin to the tube, creating a seamless, high-strength connection without soldering or welding.
Key Features
  • Strong Bond: The fins are integrally attached, reducing the risk of loosening under thermal cycling
  • High Heat Transfer Efficiency: More surface area = better heat exchange
  • Lightweight (if aluminum fins are used)
  • Corrosion-Resistant (if aluminum or stainless steel is used)
Comparison with Other Finned Tubes
Type Bonding Method Strength Thermal Performance Cost
Extruded Fins Mechanical (cold-welded) Very Strong Excellent Moderate
Embedded Fins Grooved & wrapped Good Good Lower
Welded Fins High-frequency welding Strong Very Good Higher
L-Footed Fins Crimped onto tube Moderate Good Low
Advantages Over Other Types
  • Better heat transfer than wrapped or L-footed fins
  • More durable than bonded fins (no adhesive failure risk)
  • Suitable for high-temperature cycling (unlike soldered fins)
Base Tube Material: ASTM A179

Material: Low-carbon steel (seamless cold-drawn tubes)

ASTM A179 Material Composition (Weight %)
Element Composition Range
Carbon (C) ≤ 0.06 - 0.18%
Manganese (Mn) 0.27 - 0.63%
Phosphorus (P) ≤ 0.035%

Key Characteristics
  • Cold-drawn seamless tubes: Improved surface finish and dimensional accuracy
  • High ductility (≥35% elongation) for bending/flaring without cracking
  • Moderate strength: Suitable for low/medium-pressure heat exchangers
  • Good thermal conductivity
  • Corrosion resistance in certain environments
  • Suitable for moderate-temperature applications (e.g., boilers, condensers, heat exchangers)
Comparison with Similar Standards
Standard Carbon % Tensile Strength Key Difference
ASTM A179 0.06-0.18% ≥325 MPa Cold-drawn, seamless
ASTM A192 0.06-0.18% ≥325 MPa High-temp boilers
