Investigation of Interior Corrosion of Above-Ground

Apr 05,2018 floating roof tanks Spot examination#0183;This blog,that is expected to be part of a series of blogs,will focus on a recent investigation of premature corrosion occurring inside an above-ground storage tank.A newly built carbon steel tank with a floating roof was hydro tested prior to being put in service to hold liquid petroleum products.An example of such a tank is shown in Figure 1.Inspection Practices for Atmospheric and Low-Pressure Foreword (New wording from API to be inserted.) This recommended practice is based on the accumulated knowledge and experience of engineers,inspectors and contractors that work with tanks in the oil,gas,petroleum refining,and chemical process industries.Inspecting Low-Pressure Storage Tankstank anchors,walkways,supports for internal items such as heating coils or other piping,ladders,floating roof supports welded to the shell wall and electrical conduits and fixtures) to the tank surface shall be inspected visually and by the magnet- ined,spot examination is mandatory as follows:
