摘要
基于现场采样管段的材料力学性能测试资料和焊缝缺陷检测资料,采用FAD方法对某含360°内表面裂纹管道的剩余强度进行了评价。评价结果表明,该管道在0.8MPa压力下能安全运行,在1.4MPa压力下四级地区不能安全运行。
Based on material properties of the field sampled section of pipeline and dimensions of inspected weld-ment defects,the auther analyzed the remaining strength of certain pipeline containing 360° circumferential internal surface crack with FAD method. The analytical results have shown that the pipeline is safe under 0. 8 MPa,but not safe under 1. 4 MPa in region 4.
