In 2006 we were requested to inspect an operating gas pipeline located at Mendoza Norte field starting from Gascon ll field and going to refinery Refinería Luján de Cuyo.
Evaluation of opportunities of different methods such as ILI, ECDA (CIPS, DCVG) and MTM was made beforehand. After comparing their opportunities a conclusion about the MTM method as the most suitable one was made, the conclusion was based on the impassability of the pipeline internal space for inspection and unavailability of other methods for determining internal corrosion.
Application of the MTM IS RECOMMENDED at objects where - ILI (in line inspection – Pig) or ECDA - electrometer methods in areas with detectors for internal corrosion defects - are inapplicable.
