Introduction
The ASTM A179 Boiler Tube are the standard specification for seamless cold-drawn mild steel heat exchanger and condenser tubes used in boilers and other heat transfer equipment. These tubes can withstand moderate to high temperatures and pressures, making them ideal for heat exchangers, condensers, and medium and low pressure boilers.
Applications
Heat Exchangers
Used extensively in heat exchanger units where efficient heat transfer is required between fluids at moderate temperatures and pressures.
Condensers
Ideal for condenser tubes in power plants and industrial facilities, facilitating the condensation of steam and other vapors.
Low to Medium Pressure Boilers
Commonly employed in boilers operating under low to medium pressure where corrosion resistance and thermal conductivity are essential.
Petrochemical and Refinery Plants
Used in various heat exchange processes in petrochemical and refinery operations due to their good mechanical properties and durability.
HVAC Systems
Applied in heating, ventilation, and air conditioning equipment that requires reliable heat transfer tubes.
