ASTMA179/ASME SA179 standard is applicable for steel pipes together with outside diameter of 1/8in-3in. (32 mm to 76.2 mm). 

ASTMA179/ASME SA179标准适用于外径为1/8英寸-3英寸的钢管。（32毫米至76.2毫米）。

When seamless carbon steel pipes are during the last cold drawing procedure, they will enter micro oxidization and non-oxidation heat treatment furnace for thermal treatment (Temperature is 1200℉ (650℃) if not more.). This makes the surface of cold drawn seamless steel tubes match the no oxide scale standards, and guarantees smooth surface and stable performance.

当无缝碳钢管在最后一次冷拔过程中，它们将进入微氧化和非氧化热处理家具进行热处理（温度为1200℉（650℃）或更高）。这使得冷拔无缝钢管的表面符合无氧化皮标准，保证了表面光滑和性能稳定。
