Corrosion and Chlorine Service White PaperAfter a review of CI member incidents, the HESS Issue Team found that corrosion was a factor in a considerable number of chlorine releases. HESS then formed the Corrosion Task Group in 2017, whose purpose was to evaluate the need for additional information in pamphlets to prevent chlorine releases due to corrosion. This white paper developed by the Task Group is the unified
basis for what is being recommended to include in pamphlets to address general
corrosion and corrosion under insulation (CUI). This paper and the
recommendations are only meant as a starting point of a program that will
address corrosion and CUI. It is up to individual members to develop
thorough and comprehensive paint and insulation specifications, installation
procedures, inspection programs and maintenance programs to properly protect
their plants against incidents that could arise due to corrosion.
