Wound Fin Tube ASME SA210 Gr.A-1 Aluminum ASTM B209 Gr.1060 For Air Cooler , Heat Exchager

Gr.A-1 refers to Grade A-1, a specification under ASTM (American Society for Testing and Materials) standards, specifically ASTM A210. This grade is commonly used for seamless medium-carbon steel boiler and superheater tubes. It is designed to withstand high pressure and high temperatures.

Gr.A-1 is a medium-carbon steel grade designed for high temperature and pressure applications, making it ideal for boiler and superheater tubes. When combined with ASTM B209 Gr.1060 in a wound fin tube design, it becomes highly effective in heat exchanger applications, offering robust performance and efficient heat transfer. These fin tubes are widely used in power generation, industrial boilers, and chemical processing industries, providing reliable and durable performance in demanding environments.

Chemical Composition:

Mechanical Properties:

Key Features:

• Enhanced Heat Transfer: The aluminum fins significantly increase the surface area, thereby enhancing the heat transfer rate.
• Corrosion Resistance: Aluminum fins provide good resistance to corrosion, especially in air and water environments.
• Mechanical Bonding: The wound L type fin design ensures a secure mechanical bond between the fins and the base tube, ensuring efficient heat transfer and durability.
• High Thermal Conductivity: Aluminum fins ensure high thermal conductivity, improving overall heat exchanger efficiency.
• Durable Base: The Gr.A-1 base tube provides high durability and resistance to mechanical stress under high temperatures and pressures.

Applications:

1. Boilers and Superheaters

• Power Plants: Used in steam boilers and superheaters in power generation plants to transfer heat efficiently and withstand high pressures.
• Industrial Boilers: Employed in various industrial boilers where high temperature and pressure conditions are common.

2. Heat Exchangers

• Shell and Tube Heat Exchangers: Suitable for applications where efficient thermal transfer between two fluids is required, such as in chemical and petrochemical industries.
• Air-Cooled Heat Exchangers: Ideal for systems where air is used to cool fluids, common in industrial and HVAC applications.

3. Chemical Processing

• Chemical Plants: Used in heat exchangers and condensers in chemical processing plants due to its ability to handle high temperatures and pressures.
• Petrochemical Refineries: Utilized in refineries where high strength and resistance to corrosive substances are required.
