In contrast to direct investigations and the study of nucleation and growth of stress-corrosion flaws under different external actions, statistical analysis allows one to reveal the state of a gas main and the dependence of the stress-corrosion process on different external actions. The advantage of this approach is the ability to study the actual defects of a pipeline under operating conditions; the objectiveness of the results is determined by the representativeness of a sample of the database, which rests upon a broad spectrum of external and internal actions that are revealed by intrapipe nondestructive testing (IPNT) and the possibility of accomplishing the comparative assessment of the significance of the influence factors.
