ASME SA179 Carbon Steel Low Fin Tubes For Heat Exchanger Tube HT And ECT

Product Specification

ASME SA179 Carbon Steel Low Fin Tubes For Heat Exchanger Tube HT And ECT

Product Overview:

The ASME SA179 Carbon Steel Low Fin Tubes are designed for heat exchanger applications that require high thermal efficiency and durability. These tubes feature a low fin design, where aluminum fins are mechanically bonded to the base tube (made of ASTM A179 carbon steel). The Low Fin Tube design enhances the surface area for heat transfer while maintaining compactness. The tubes are used in heat exchangers, air coolers, and condensers, with testing such as Heat Treatment (HT) and Eddy Current Testing (ECT) to ensure high-quality performance and reliability.

Key Features

1. Base Tube Material: ASME SA179 Carbon Steel

• ASME SA179 is a low-carbon seamless steel tube material known for its good thermal conductivity, weldability, and mechanical strength.

• This material is commonly used in heat exchangers, boilers, condensers, and cooling systems, where efficiency and durability are critical under high-temperature and high-pressure conditions.

2. Fin Type: Low Fin Tube Design

• Low Fin Tubes feature small, closely spaced fins, which are designed to increase the surface area for heat exchange.

• The design reduces air resistance while improving the heat transfer performance. This makes the tube suitable for compact heat exchanger systems where high heat dissipation is required in limited space.

3. Application: Heat Exchanger Tubes, Air Coolers, Condensers

• These low fin tubes are used in heat exchangers, condensers, and air coolers, which are often found in HVAC systems, power plants, chemical processing, and industrial cooling applications.

• They offer increased heat transfer for effective cooling in systems exposed to high temperatures and mechanical stresses.

4. Heat Treatment (HT) & Eddy Current Testing (ECT)

• Heat Treatment (HT): The tubes are heat-treated to ensure they meet the desired mechanical properties, strength, and corrosion resistance for use in high-temperature applications.

• Eddy Current Testing (ECT): Non-destructive testing (NDT) using Eddy Current Testing ensures that the tubes are free from surface defects, such as cracks, pits, and other flaws that could affect the tube's performance in heat exchangers.

Advantages of Low Fin Tubes for Heat Exchangers

1. Increased Heat Transfer Efficiency:

   • The low fin design provides a larger surface area for effective heat exchange, improving the heat dissipation from the fluid inside the tube to the surrounding environment.

2. Compact Design:

   • The low fin height allows for a compact tube design, making these tubes ideal for applications with limited space, such as condenser systems and air coolers.

3. Corrosion Resistance:

   • The aluminum fins offer excellent resistance to oxidation and corrosion, ensuring the durability and longevity of the heat exchanger system, particularly in humid or chemically aggressive environments.

4. Enhanced Performance with HT and ECT:

   • Heat treatment (HT) ensures that the tubes meet the required mechanical properties to withstand high temperatures.

   • Eddy Current Testing (ECT) ensures the tubes are free from surface defects, improving the reliability and performance of the heat exchanger.

5. Cost-Effective:

   • The combination of carbon steel base tubes and aluminum fins offers a cost-effective solution without compromising on heat transfer efficiency or durability.

Applications

• Condenser Tubes: Used in cooling systems to condense vapor into liquid in industrial and HVAC systems.

• Heat Exchanger Tubes: Ideal for use in chemical processing, petrochemical plants, power plants, and HVAC systems where heat needs to be transferred efficiently between two fluids.

• Air Coolers: Employed in air-cooling systems in industries that require effective heat dissipation.

• HVAC Systems: Used in large-scale air-conditioning systems for cooling and heat exchange.

Conclusion

The ASTM A179 / ASME SA179 Carbon Steel Low Fin Tubes offer an efficient and durable solution for heat exchanger applications, particularly in condensers, coolers, and HVAC systems. With their low fin design, corrosion resistance, and the added benefits of heat treatment (HT) and eddy current testing (ECT), these tubes provide high thermal efficiency, long-term reliability, and cost-effectiveness in industrial cooling applications.
