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%
Sulfur (S)	≤ 0.035%
Silicon (Si)	≥ 0.10% (typically 0.25-0.50%)
Iron (Fe)	Balance (≥ 98%)

ASTM A179 Mechanical Properties

Property	Value
Tensile Strength	≥ 325 MPa (47,000 psi)
Yield Strength	≥ 180 MPa (26,000 psi)
Elongation (in 2")	≥ 35%
Hardness (Rockwell B)	≤ 72 HRB

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
ASTM A106	0.30% max	≥415 MPa	Higher strength, piping

Why ASTM A179 for Finned Tubes?

Excellent thermal conductivity (better than stainless steel)
Cost-effective vs. alloy tubes
Compatible with aluminum fins (extrusion-friendly)
