5. Conclusions. The analyses, of cast iron pipelines failed in work, confirmed the great critical issues of these component in opera, especially for critical applications as that of gas transportation. Considering that cast iron pipelines will be operative for a long time before their complete substitution, a monitoring system based on FBG sensors has been proposed. That system could at least indicate in real time potential structural failures of pipelines.
