标准摘要
[中文适用范围]: 本规范涵盖了由钢板制成的结构钢管的制造,具有纵向和环向对焊缝,通常尺寸为 14 英寸外径 (OD) 及更大(LWDS 为 40 英寸及更大),壁厚为 3/8 英寸. 和更大(标称长度可达 40 英尺),适用于焊接海上结构的建造。 ERW 工艺或螺旋焊管的使用不包括在本规范中。根据本规范制造的管道主要用于打桩和主要结构构件,包括通常不需要内部加强筋的管状桁架连接。希望将 API 会标应用于本规范涵盖的产品的制造商应证明教育、培训、经验和/或考试计划令美国石油学会满意,以确保制造商的人员有能力进行焊接、检验、无损检测,以及本规范要求或引用的测试。 [外文原描述]: Covers the fabrication of structural steel pipe formed from plate steel with longitudinal and circumferential butt-welded seams. Pipe is typically in sizes of 14 in. outside diameter and greater, with a wall thickness 3/8 in. and greater (up to a nominal 40 ft in length) and is suitable for use in construction of welded offshore structures. The use of the ERW process or spiral welded pipe is not included in this specification. Pipe fabricated under this specification is intended to be used primarily in piling and main structural members, including tubular truss connections, where internal stiffeners are not usually required.
