Estimation of tensile strain capacity for thin-walled API X70 pipeline with corrosion defects using the fracture strain criteria

Various tensile strain capacity (TSC) prediction equations have recently been presented by many research organizations such as Pipeline Research Council International and ExxonMobil Corporation. The gas industry uses these equations to determine the allowable strain for the cracked pipe. However, these TSC prediction equations cannot be applied to pipes with other defects such as corrosion or mechanical damage. Corrosion defects are the most...
