本SAE标准涵盖了标准化电阻焊接闪光控制单壁低碳钢压力管，用于压力管道和其他要求管道质量适合弯曲、双扩口、卷边、成型和钎焊的应用。根据本规范生产的材料不适用于单火炬应用，因为内径（ID）焊道或划痕区域可能会导致泄漏路径。在单火炬应用中使用该材料时的风险承担应由生产商和买方之间的协议确定。 本规范还包括SAE J356 A型管。SAE J356和SAE J356 A型的机械性能和性能要求相同。SAE J356或SAE J356类型- 名称定义了卷材和直材之间独特的制造差异。ISO 10763中列出了公制管道的标称参考工作压力，SAE J1065中列出了英制管道的标称参考工作压力。SAE J356采用经过二次热处理操作的直线长度生产。SAE J356 A型管经过在线热处理以释放应力，并以盘管形式生产。 为了在全球市场内实现标准化，并确保公司在国际市场上保持竞争力，我们打算将其转换为公制管尺寸，这将: –建立一个全球系统–引导用户使用首选系统–降低复杂性–消除库存重复

This SAE Standard covers normalized electric-resistance welded flash-controlled 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, double flaring, beading, forming, and brazing. Material produced to this specification is not intended to be used for single flare applications, due to the potential leak path caused by the Inside Diameter (ID) weld bead or scarfed region. Assumption of risks when using this material for single flare applications shall be defined by agreement between the producer and purchaser. This specification also covers SAE J356 Type-A tubing. The mechanical properties and performance requirements of SAE J356 and SAE J356 Type-A are the same. The SAE J356 or SAE J356 Type-A designation define unique manufacturing differences between coiled and straight material. Nominal reference working pressures for this tubing are listed in ISO 10763 for metric tubing, and SAE J1065 for inch tubing. SAE J356 is produced in straight lengths that undergo a secondary heat treat operation. SAE J356 Type-A tubing is heat treated in-line to relieve stresses, and is produced in coil form. In an effort to standardize within a global marketplace and ensure 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
