The present work carried out the internal inspection of the pipeline that allows the natural gas transport from the “Compresora Lisama” to the gas plant “El Centro” in Santander, Colombia, establishing the current pipeline conditions and defining the actions that must be taken to maintain the safety of the process. The internal inspection was carried out using Magnetic Flux Leakage technology, which allowed identifying in a single run the different types of anomalies that may occur in the 8” diameter steel pipeline during natural gas transport. The anomalies identified during the internal inspection inherent to natural gas transport through water bodies and unstable soils of variable height corresponded to thickness losses, dents, and programmed anomalies with estimated repair factor greater than 1. These anomalies were grouped into a total of 41 sections of the “Lisama–El Centro” gas pipeline that require replacement to guarantee the correct operation of the “Compresora Lisama” and the gas plant “El Centro”, preventing unscheduled plant shutdowns that may lead to shortages in communities and companies that require daily the natural gas.
