本SAE标准涵盖标准化电阻焊、冷拉、单壁低碳钢压力管，旨在用作压力管线以及其他需要适合弯曲、扩口、成型和钎焊的管道质量的应用。 为了在全球市场内实现标准化并确保公司能够在国际市场上保持竞争力，我们打算转换为公制管尺寸，这将: 通向一个全球系统 将用户引导至首选系统 降低复杂性 消除重复库存

This SAE Standard covers normalized electric-resistance welded, cold-drawn, single-wall, low-carbon steel pressure tubing intended for use as pressure lines and in other applications requiring tubing of a quality suitable for bending, flaring, forming, and brazing. In an effort to standardize within a global marketplace and ensuring that companies can remain competitive in an international market it is the intent to convert to metric tube sizes which will: Lead to one global system Guide users to preferred system Reduce complexity Eliminate inventory duplications
