Full Scale Corrosion Test on Buried Cast Iron Pipes

Abstract

Underground metal pipes are essential infrastructure for water and energy transport. Although the life expectancy of cast iron pipes can exceed one hundred years, the failures of cast iron pipelines often occur unexpectedly as the corrosion causes material deterioration, which induces that the actual service life of pipeline greatly less than the design life expectancy. A systematic research program has been developed to investigate the effect of corrosion on material deterioration of pipelines buried in soil, which are essential for accurate prediction of life expectancy. The details of apparatus, test preparation, corrosion monitoring and measurements are presented in this paper. The research methodology shows effective outcomes for monitoring and evaluating corrosion of metal pipes buried in realistic fine grained soil medium. The current research provides useful knowledge for engineers and asset managers to make maintenance strategies for corrosion affected cast iron pipelines.
