Study on the Burst Limit States of Submarine Pipeline under Internal Corrosion

摘要：

　　Burst limit states are fundamental to the study of submarine pipeline under long internal corrosion.In this paper, a new burst limit function is proposed.Firstly, analytical solution of burst limit function of intact pipeline is worked out.Considering longitudinal internal corrosion, burst limit function is modified.Additionally, the modified limit function is further perfected by multiple regression analysis.Finally ,the above function is compared to former models, verifying its accuracy in dealing with submarine pipeline under long internal corrosion.
