Lifetime Prediction of Fire Extinguishing Pipeline by Means of Extreme Value Statistics
This study represents the lifetime prediction of fire extinguishing pipeline within the framework of corrosion. In this case, carbon steel was used as a material for fire extinguishing pipeline. Total 24 samples were selected, which was determined by specimens position, pipeline diameter, and pipeline thickness. Used test methods were view inspection and extreme value statistics using the Gumbel distribution. Especially, by utilizing extreme value statistics, the prediction of remaining life was confirmed as a specific numerical value. As a result of view inspection, pitting corrosion was occurred in several samples. In addition, extreme value statistics demonstrates that several pipelines were very sensitive at pitting corrosion. However, the pitting corrosion of all pipelines was not critical; thus, all pipelines dont need to be changed for a safety regulation.
