Product Details

Cold-drawn ASTM A179 / ASME SA179 Carbon Steel Seamless Tube Heat Exchanger Tube

ASTM A179/ ASME SA179 tubes have good mechanical properties including high tensile strength and good ductility, a low carbon content which makes them suitable for bending, flaring, and other forming operations. It also makes them suitable for high-pressure and high-temperature applications, which are commonly used in industries such as oil and gas, chemical processing, power generation, and HVAC systems where efficient heat transfer is essential. A179 tubes have a smooth and clean surface finish, which is important for heat transfer applications. The tubes are usually coated with a light oil or phosphate coating to prevent oxidation and corrosion during transportation and storage.

A179 tubes can be used in heat exchangers in two main forms: straight tubes and U-bend tubes.

Straight Tubes: Straight A179 tubes are the most common form used in heat exchangers. They are available in various lengths and can be easily installed in a straight configuration. Straight tubes are typically used in applications where the heat transfer requirements can be met with a simple layout. They are suitable for applications where the fluid flow is relatively straightforward and does not require complex tube routing.

U-Bend Tubes: U-bend A179 tubes are specifically designed for heat exchangers that require a compact and efficient design. These tubes are bent into a U-shape with precise dimensions and tight tolerances. The U-bend configuration allows for a more compact layout, reducing the space required for the heat exchanger. U-bend tubes are typically used in applications where space is limited or where the heat exchanger design demands a specific tube arrangement.
