ASTM A179 Tubing Low Carbon Steel Heat Exchanger Tube Cold Drawn Seamless
A179/SA179 Low-Carbon Steel Seamless Tube, Cold-Drawn And Oiled, For Shell-And-Tube Heat Exchanger
Overview A179/SA179 Low-Carbon Seamless Tube
ASTM A179 / ASME SA179 carbon steel seamless tubes are specifically designed for use in heat exchangers, condensers, and similar heat transfer systems. These tubes are manufactured using a cold-drawn seamless process, providing thin walls, high precision, and excellent heat transfer performance. Made from low carbon steel, they offer good formability and are widely used in power plants, refineries, and petrochemical applications.
A179 seamless tubes are the "king of cost-effectiveness" in the heat exchange field. Designed specifically for medium-to-low temperatures and non-aggressive corrosive environments, they are used in over 90% of shell-and-tube heat exchangers globally. When selecting specifications, it is crucial to strictly distinguish between ASTM A179 (material standard) and ASME SA179 (manufacturing standard), as both share identical technical parameters.
Why Choose ASTM A179 / ASME SA179 CS Seamless Tubes?
|
Reason |
Benefit |
|---|---|
|
1. Excellent Heat Transfer |
The low carbon content and thin wall design allow for high thermal conductivity, making A179 ideal for heat exchangers and condensers. |
|
2. Seamless Construction |
Seamless tubes provide uniform strength, eliminate risk of weld failure, and ensure better pressure and corrosion resistance. |
|
3. Cold-Drawn Precision |
The cold-drawn process gives tight dimensional tolerances, smooth surface finish, and enhanced mechanical properties. |
|
4. Good Formability |
The material is easy to bend, expand, or flare during fabrication, which is critical in tubular heat transfer systems. |
|
5. Cost-Effective |
Compared to alloy or stainless steel, A179 offers a lower-cost solution for applications where corrosion resistance is not the primary concern. |
|
6. Standardized Quality |
Widely used and regulated under ASTM/ASME standards, ensuring global availability and compliance. |
