Abstract
Corrosion is a major cause for buried gas pipeline failure. Current design guidelines are limited to pressure loading for assessing corroded pipeline's integrity. A few studies were conducted by other researchers to determine the remaining bending or pressure strength of the corroded pipelines under combined loading. No study was conducted to determine the axial compressive strength of the corroded pipelines although it could be the major cause of pipeline failure. Therefore, the current study was completed using full-scale tests and a parametric study using FEA to assess the integrity of X46 corroded pipe subjected to severe axial compression and internal pressure. Test specimens showed high ductility and never ruptured. The finite element analysis, however, showed that this pipe may rupture if internal pressure and/or corrosion dimensions are changed. The parametric study helped to develop a guidelines that the pipeline operators can use for assessing the safety of their corroded pipelines.
