SA-179 es una tubería de acero de carbono en frío y baja en carbono estándar estadounidense para condensadores e intercambiadores de calor. El Estándar Ejecutivo: SA-179M-2010 Tuberías bajas de carbono de color frío sin costuras para intercambiadores de calor y condensadores. Se utiliza principalmente para intercambiadores de calor, como tubos en U. El material de SA179 correspondiente a China es GB8163 10# tubería de acero sin costuras.
La tubería de acero sin costuras SA-179 tiene una sección hueca y se usa ampliamente como una tubería para transportar fluidos, como tuberías para transportar petróleo, gas natural, gas, agua y ciertos materiales sólidos. En comparación con el acero sólido, como el acero redondo, la tubería de acero es de peso más ligera cuando la resistencia a la flexión y la torsión es la misma, y es una sección económica de acero.
