Study on Residual Strength of Corroded Pipes

Abstract:

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