Limit Spacing of Asymmetric Double Corrosion Defect Interaction in Pipeline
Corrosion defects of various forms can occur over time in pipelines,and the interaction between adjacent corrosion defects can impact the pipeline's failure pressure.However,there has been no comprehensive study on the interaction limit spacing of pipelines with asymmetric corrosion defects.In light of this,the finite element method was employed to investigate the interaction limit spacing of pipes with asymmetric double corrosion defects.Initially,the reliability of the finite element modeling of multi-corrosion defects was validated through the Benjamin blasting test.Building upon this,length asymmetric corrosion defects and depth asymmetric corrosion defects in the axial direction,as well as length asymmetric corrosion defects and depth asymmetric corrosion defects in the circumferential direction was examinesd.The findings indicate that the interaction limit spacing of asymmetric corrosion defects obtained in this article is more accurate in evaluating asymmetric corrosion defects.
