Fatigue and burst tests of full-scale girth welded pipeline sections for safe operations

Abstract The main objective of our ongoing research is data collection for integrity management (IM) tasks, in other words pipeline system (PIMS), helping the transporting operators different decision situations. Either reserves girth welds after a long-term operation can be identified or with defects should repaired and/or replaced. From operators’ point view, cost-effective way; however, from safety managing lifecycle more reliable way. Unfortunately, inadequate cause catastrophic damages pipelines, all over world. Consequently, optimal pipelines complex task. paper introduces investigation program executed on full-scale sections. Fatigue (100,000 cycles) and burst tests were sections containing welds. Long-term operated replaced gas sections, furthermore, both appropriate investigated. testing results damage histories compared each other; factor (SF) was defined calculated assessment reliability
