Advantages of Base Tubes A179 For HVAC And Refrigeration
Excellent thermal conductivity: ASTM A179 is cold‑drawn low carbon steel with min. wall thickness, providing stable and efficient heat transfer, ideal for condensers, evaporators and heat exchangers.
Good formability and weldability:easy to machine, expand and weld, making it highly suitable for manufacturing.
Suitable for moderate pressure and temperature: meets the working conditions of most HVAC, refrigeration, chillers, dry coolers and air‑cooled heat exchangers.
Most important is the cost‑effective,lower cost compared with copper and stainless steel, while satisfying performance requirements, helping to reduce unit production cost.
