A179 CARBON STEEL EXTRUDED LOW FINNED TUBE INNER FIN FOR AIR COOLER

 
 
Overview
 

The A179 carbon steel extruded low finned tube with inner fin is a type of tube used in air coolers. It is made from carbon steel and has a low fin configuration on the outer surface to enhance the heat transfer efficiency. The inner fin inside the tube further increases the heat transfer surface area, making it ideal for applications that require efficient cooling or heating. This type of tube is commonly used in industries such as power generation, petrochemical, and HVAC systems.

 

 

Advantage of using low fin tubes in various applications:

• Increased Heat Transfer Efficiency: The low fin configuration on the outer surface of the tube increases the surface area, allowing for enhanced heat transfer. This results in improved cooling or heating performance.
• Compact Design: The low fin tubes are designed to maximize the heat transfer area within a limited space. This makes them ideal for applications where space is a constraint.
• Cost-effective Solution: Low fin tubes provide a cost-effective solution compared to other heat transfer enhancement methods. They offer improved heat transfer efficiency without requiring significant modifications to the equipment or system design.
• Reduced Fouling and Scaling: The presence of fins on the tube surface helps to disrupt the formation of fouling and scaling, reducing the maintenance and cleaning requirements.
• Versatility: Low fin tubes can be manufactured using various materials, such as carbon steel, stainless steel, copper, or aluminum, depending on the specific application requirements. This makes them suitable for a wide range of industries and applications.
• Higher Fluid Velocity: The presence of low fins increases the fluid velocity between the fins, promoting better heat transfer and reducing the risk of stagnant zones where fouling can occur.

 

Overall, low fin tubes offer improved heat transfer performance, compact design, cost-effectiveness, and versatility, making them a popular choice for various cooling and heating applications.

Common Application:
 

• Air Coolers: Low fin tubes are widely used in air coolers, including air-cooled heat exchangers, condensers, and evaporators. The increased surface area provided by the low fins allows for better heat dissipation, making them more efficient in cooling applications.
• Heat Exchangers: Low fin tubes are utilized in various types of heat exchangers, including shell and tube heat exchangers and plate heat exchangers. The increased heat transfer capacity of the low fins improves the overall efficiency of the heat exchange process.
• HVAC Systems: Low fin tubes are used in heating, ventilation, and air conditioning (HVAC) systems for efficient heat transfer. They are often found in air handling units, chillers, and air conditioning coils.
• Power Generation: Low fin tubes are widely used in power plants for heat recovery systems, such as economizers, air preheaters, and heat exchangers. The enhanced heat transfer provided by the low fins improves the overall energy efficiency of the power generation process.
• Petrochemical Industry: Low fin tubes are utilized in various petrochemical processes, including oil refineries, chemical plants, and natural gas processing plants. They are used in heat exchangers, coolers, and condensers to facilitate efficient heat transfer in these industrial processes.
• Refrigeration Systems: Low fin tubes are employed in refrigeration systems, including commercial refrigeration units, ice-making machines, and refrigeration coils. The increased surface area provided by the low fins helps to improve the cooling capacity of these systems.
