摘要：

Circumferential failure may occur in defective girth weld when it is under high longitudinal tension. This paper presents methodology and design criteria for assessment of pipeline girth weld defects (circumferential failure). For limit state design, the paper covers major failure modes such as plastic collapse and fracture. Both corrosion defects and cracklike defects are considered. Strength equations are reviewed and compared.
