The problem currently being faced is the occurrence of pipe leakage due to corrosion under insulation. The purpose of this study is to provide an overview of the specifications and ways of applying high-density calcium silicate insulation material as a substitute for rock wool mineral insulation material that has been used since the beginning of the refinery construction. This research method used the application research method with the case study approach method, which is a case study of pipe leakage problems due to corrosion under insulation. The results showed that the emergence of corrosion problems under insulation was due to rock wool mineral material storing and depositing water in the insulation. The observations also showed that after the insulation was replaced, the temperature of the steam fluid in the piping increased by 9-14°C and the results of observation through widow inspection revealed that the calcium silicate condition remained dry and the piping condition did not indicate corrosion. The results of this study indicated that high-density calcium silicate material was suitable and also recommends corrosion control under insulation by replacing rock wool mineral material into high-density calcium silicate.
