Regarding the tank covered with insulation, The service is hydrocabon that service temperature is around 60C to 80C. I found corrosion underside/ leaking through bottom plate during tank shutdown.The corrosion was created from underside because the topside steel surface quite smooth and there was no scale, no significant metal loss (MFL evaluation). The tank is on concrete ring wall with sand cushion wiht leak detection. Can anyone stimulate the situatuion of underside corrosion occurrence incase the CP is still active?
