ASTM A179 Carbon Steel Seamless Internally Low Fin Tubes For Air Coolers

ASTM A179 Carbon Steel Seamless Internally Low Fin Tubes For Air Coolers

ASTM A179 This specification covers minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus.This specification covers tubes 1⁄8 to 3 in. [3.2 to 76.2 mm], inclusive, in outside diameter.

Mechanical Properties

Definition

Low fin tubes are a type of enhanced heat transfer tube specifically designed for applications like air coolers, where efficient heat exchange between a fluid inside the tube and air outside is required. These tubes have a lower fin height compared to other finned tubes, making them ideal for compact and efficient heat exchanger designs.Typically constructed from materials such as carbon steel, stainless steel, alloy or copper, providing durability and resistance to corrosion.

Low fin tubes are an excellent choice for air coolers, offering a balance of thermal efficiency, compactness, and cost-effectiveness. Their design makes them particularly suitable for applications where space and weight are critical considerations.

Advantages

1.The increased surface area improves thermal efficiency and enhanced heat transfer.

2.Corrosion resistance, wear resistance, low contact thermal resistance;

3.The compact design allows for smaller heat exchanger units and lower the cost.

4.The smooth fin surface minimizes fouling compared to high-fin tubes.
