Product Description

ASTM A179 Carbon Steel Extruded Fin Tube For HVAC Economizers

HVAC Economizers (Flue Gas/Air Heat Exchangers) are installed in the flue ducts of boilers/chillers, with A179 extruded fin tubes as the core component:cold water/fresh air flows inside the tubes, while high-temperature flue gas passes outside the tubes.Fins of fin tubes increase the outer surface area by 8–12 times, with heat transfer efficiency far exceeding bare tubes.ASTM A179 has high thermal conductivity (45–50 W/m·K), excellent pressure resistance, high ductility (suitable for extrusion process).

Chemical Composition (%) Maximum

Grade	C	Mn	P	S
A179	0.06-0.18	0.27-0.63	0.035	0.035

Mechanical Properties

Grade	Tensile Strength min	Yield Strength min	Elongation in 2" or 50mm min
A179	47ksi (325 MPa)	26ksi (180 MPa)	35%

Some Important Advantages of A179 Extruded Fin Tubes for HVAC Economizers

Medium and Low Temperature Conditions: The temperature resistance limit of aluminum fins is approximately 260°C (500°F), perfectly matching the flue gas temperature of HVAC boilers.

A179 High Cost Performance: 50–70% lower cost than stainless steel and copper-nickel alloys.Compact Design: Smaller equipment size under the same heat transfer capacity, saving machine room space.

Applications of A179 Extruded Fin Tubes

Economizers supporting gas/oil-fired boilers

Industrial Plant HVAC: Waste heat recovery for hot water/steam boilers

District Heating/Cooling: Combined heat and power (CHP) systems

Heat Pumps and Chillers: Evaporators/condensers of flue gas heat pumps.

It's hot and humid here, and our old wrap-on tubes used to rust like crazy. Switched to your extruded ones—the aluminum fin covers the steel pipe perfectly, so corrosion shouldn't be an issue.

Tube ends were clean, dimensions accurate. Our fitters didn't complain about fit-up.

No corrosion issues so far, though we're running below dew point carefully. Installation was straightforward—tube sheets lined up, ends clean, rolling into the header went smooth.
