This work concerns the study of the reliability of 5LX60 steel pipes for the transport of gas under the effect of corrosion failures, particularly corrosion peaks. The objective is to determine the life time of the pipes by estimating the probability of failure based on a parametric approach where the variables are considered. Initially, an ASME B31G-based calculation model is used to calculate the operating safety pressures in the corroded pipes. This method is usually deterministic. The application of a probabilistic method implies the knowledge of the variables and the dimensions, and which give us the reliability of the models used to calculate the pressures.
