ASTM A179 Carbon Steel Wound Finned Tube For HVAC Systems

Product Description

Built with cold-drawn, low-carbon seamless tubing that meets ASTM A179, this wound-finned tube multiplies the external surface by aluminum or copper fins, delivering superior heat transfer in air-handling coils. Operating from –29 °C to 400 °C, it retains ≥325 MPa tensile strength while keeping hardness ≤72 HRB, resisting corrosion, fouling and wear. The extended surface cuts air-side thermal resistance, lifting evaporator and condenser capacity by 15 % and helping chillers reach premium IPLV values.
