摘要：To study the effect of interaction between colonies of defects on the burst pressure of corroded pipeline, ten experimental cases were designed. Among them, the specimens containing two longitudinal or circumferential aligned defects with different sizes and spacings were fabricated. Burst tests were conducted on the ten tubular specimens. Burst pressures and strains on the surface of defects were measured. The effects of defect sizes and spacings on burst pressures and strains of corroded pipeline were analyzed. Meanwhile, based on the experimental results, the performance of the five interaction rules such as DNV RP F101, API 579, BS 7910, Kiefner and Vieth, Pipeline operator forum (POF) on failure pressure are evaluated.
