External organic coatings have been used in Venezuelan pipelines to prevent corrosion in different environments. These environments can be considered critical due to the high temperature of the fluid transported or due to the aggressiveness of the surrounding soils and waters. It has also been found that inadequate application of the coating has contributed greatly to a premature failure.

An overview of the techniques used to determine the causes of the failures and the interpretation of the failure analysis will be presented in detail in this paper.
