摘要
采用热轧卷板,经过卷板开平和切断、JCOE工艺制成直缝埋弧焊接钢管,分别进行了成分、拉伸、冲击、硬度、DWTT等理化性能试验,无损检测和外观等质量状况检测和评价,结果符合相关技术规范DNV-OS-F101(2000)和API SPEC 5L(43版)的要求。
Adopting HRC, through leveling, cutting and JCOE process, to make LSAW pipe, and then conducted chemical composition, tensile ,impact, hardness and DWTT tests, as well as non-destructive and appearance inspections, the results conformed to the requirements of DNV -OS -F101（2000） and API SPEC 5L specification.
