焊接闪光控制 SAE 1021 碳钢管材 冷成型标准化 焊接和钎焊

[中文适用范围]： SAE 标准涵盖标准化电阻焊闪光控制单壁@碳钢压力管，旨在用作压力管线以及其他需要质量适合冷成型@焊接和钎焊的管材的应用。根据此规格生产的材料不应用于单喇叭口应用，因为内径焊道或斜接区域可能会导致潜在的泄漏路径。将这种材料用于单一火炬应用时的风险假设由生产商和管材采购商之间的协议确定。按照此规格生产的材料等级的碳和锰含量高于 SAE J356 中指定的材料等级，并且旨在服务于比 SAE J356 同等尺寸更高的压力应用。由于碳和锰含量较高，成品管的成型特性与 SAE J356 产品相比有所减弱。在指定按本规范生产的材料时，应特别注意成品组件的整体成型要求。为了在全球市场中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： 形成一个全球系统 引导用户使用首选系统 降低复杂性 消除库存重复 [外文原描述]： This SAE Standard covers normalized electric resistance welded flash controlled single-wall, SAE 1021 carbon steel pressure tubing intended for use as pressure lines and in other applications requiring tubing of a quality suitable for bending, double flaring, cold forming, welding, 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.The grade of material produced to this specification is higher in carbon and manganese content than the grade of material specified in SAE J356 and is intended to service higher pressure applications than equivalent sizes of SAE J356. Due to the higher carbon and manganese content, the forming characteristics of the finished tube are diminished versus the SAE J356 product. Special attention to the overall forming requirements of the finished assembly shall be taken into consideration when specifying material produced to this specification. Refer to SAE J2551-1 for additional design and fabrication guidance associated with this material. Nominal working pressures for this material are listed in ISO 10763 and SAE J1065. When required, qualitication testing shall be in accordance with ISO 19879.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 a preferred system.Reduce complexity.Eliminate inventory duplications.Cross Reference: ASTMA450/A450M,ASTMA513,IS19879,ISO10583,ISO10763,ISO3305,ISO5598,ISO8434-2,ISO8434-3,J1065_201605,J1453,J1677_201612,J2551/1_201804,J2551/2_201804,J2551/3_201804,J2592_201901,J403,J409_202107,J514,J533_201702
