During the long-term operation of pipelines, corrosion defects with different forms may occur, and there is interaction between adjacent corrosion defects, which affects the failure pressure of the pipeline. However, there has been no systematic study on the interaction limit spacing of asymmetric corrosion defect pipelines. In view of this, this article adopts the finite element method to study the interaction limit spacing of pipelines with asymmetric double corrosion defects. Firstly, the reliability of the finite Metamodeling of multiple corrosion defects in Benjamin blasting test was verified. On this basis, research was conducted on length asymmetric corrosion defects and depth asymmetric corrosion defects in the axial direction, while also investigating length asymmetric corrosion defects and depth asymmetric corrosion defects in the circumferential direction. The research results indicate that for pipelines with asymmetric corrosion defects, SL=1.5(Dt)0.5 ^and Sc=1.25(Dt)^0.5 are the limit spacing for the interaction between asymmetric double corrosion defects.
