摘要: Corrosion is a very common defect for pipes under the sea after some service time, and it causes deterioration of pipe’s strength due to reduction tube wall thickness. To provide reliable assessment on residual pipe corrosion important in safety evaluation such pipes. This study presented both experimental numerical investigations static corroded Flexural test carried out, tested results prove decrease this specimen. Furthermore, finite element modeling method proposed, reliability model evaluated through comparison with results. Using model, effect sizes has been analyzed discussed.
