ASTM A179/ ASME SA179 Carbon Steel Low Fin Tubes For Heat Exchanger

Product Overview:

The ASTM A179 / ASME SA179 Carbon Steel Low Fin Tubes are designed for high-performance heat exchanger applications. These tubes are constructed from low-carbon steel (ASTM A179), offering excellent thermal conductivity, mechanical strength, and corrosion resistance. The low fin design increases the heat transfer surface area, improving the overall efficiency of heat exchangers, air coolers, and condensers. These tubes are ideal for industrial cooling systems where energy efficiency and high heat dissipation are required.

Key Features

1. Base Tube Material: ASTM A179 / ASME SA179 Carbon Steel

• ASTM A179 (or ASME SA179) is a low-carbon steel tube known for its thermal conductivity and mechanical properties.
• This material is ideal for use in heat exchangers, boilers, and condenser systems, where high-efficiency heat transfer and resilience to mechanical stress are required.
• The low-carbon content of the tube ensures good weldability and ease of fabrication, making it a cost-effective choice for a wide range of industrial applications.

2. Fin Type: Low Fin Tube Design

• Low fin tubes feature fins with a small height (usually around 5 to 10 mm) that are closely spaced along the base tube. This design increases the surface area for heat exchange while reducing air-side resistance, leading to higher thermal efficiency and improved heat dissipation in air-cooling systems.
• The low fin design is particularly useful in space-limited applications, where compactness is essential without sacrificing performance.

3. Application: Heat Exchanger, Condensers, Air Coolers

• These low fin tubes are ideal for use in air-cooled heat exchangers, cooling towers, condensers, and HVAC systems.
• The increased surface area provided by the low fin design enhances the heat transfer capabilities of the system, making it suitable for industrial applications requiring efficient cooling.
