Abstract：
The specimens of girth weld joint of ＜D813mm×14.7mm pipeline cracked at ＂near-seam zone＂ in tensile test. It was considered unacceptable for strain-based design pipelines in some current standards. The girth weld joint for X70 pipelines with ＂near-seam zone＂ crack were researched by CWP test and single-edge notch test (SENT). The high strain capacity is demonstrated by resistance curve tangency approach and CWP test results. The results imply the considerable tensile fracture resistance and consequently strain capacity when the strength overmatch.
