ASTM A179 is a seamless low-carbon steel tube, designed to offer excellent thermal conductivity and strength for heat transfer applications.
This material is widely used in heat exchangers, boilers, and cooling systems where efficient heat exchange is essential.
Low-carbon steel is chosen for its high strength-to-weight ratio and ability to handle pressure and temperature variations, making it perfect for industrial air-cooled condensers.
Extruded aluminum fins (Al-1060) are known for their excellent thermal conductivity and lightweight properties, making them ideal for air-cooled heat exchangers.
Extrusion ensures the fins are tightly bonded to the base tube, ensuring no detachment over time, even in high-temperature and high-pressure environments.
Al-1060 aluminum provides superior corrosion resistance, especially in humid environments or where exposure to moisture and aggressive chemicals is common.
Al-1060 is a high-purity aluminum alloy that is resistant to corrosion, particularly in water or air-cooled systems exposed to the environment.
Aluminum fins offer lightweight performance without sacrificing heat dissipation, making the tube ideal for air-cooled condensers and cooling systems where space is limited and efficiency is paramount.
ASTM A179 Extruded Fin Tubes with Al-1060 Fins are commonly used in air-cooled condensers, where the goal is to transfer heat from a fluid (usually steam) to the surrounding air.
The extruded fin tube design ensures that maximum heat transfer is achieved in space-constrained environments, making it perfect for HVAC systems, chemical processing plants, power plants, and other industrial cooling systems.
