Corrosion Failure Investigation-Case Study
The presentation of Wayne D. Niemeyer ( 2nd case starting from 17:00) has demonstrated the importance of understanding of process and production chemistry for the corrosion root cause analysis(RCA). This principle is prompted by ASTM G161 Standard Guide for Corrosion-Related Failure Analysis The most important observation from this case is to determine the chemistry of fluid not only from normal production, but also from upset stage. This could be a challenge in certain plant/process due to cost-saving practice by minimising “unnecessary” monitoring. RCA may run into the dead end without weekly lubricant sample been analysed. The final conclusion was leaking of…
