If existing plates are to be used to reconstruct the tank, they shall be checked for what?

• A. Chemical compatibility with other plates used in the reconstruction
• B. Excessive corrosion and pitting
• C. Mechanical strength including impact properties
• D. Inadequately reinforced openings

Answer: (B)

When reconstructing a tank using existing plates, it is essential to check for excessive corrosion and pitting. This is critical because the structural integrity of the tank largely depends on the condition of its plates. Corrosion can weaken the material significantly, leading to potential failure under operational stresses or environmental conditions. Pitting, which involves localized corrosion that leads to small holes or pits in the metal, can further compromise the strength of the plates and create weak points that are more susceptible to failure. Therefore, assessing the extent of corrosion and pitting is vital in determining whether the existing plates are still suitable for safe use in the tank reconstruction process. The other considerations, while relevant to overall tank integrity and safety, may not be the first priority when it comes to reusing existing plates. For instance, checking chemical compatibility is important but typically pertains more to the materials used for contents or coating rather than the structural integrity of plates. Mechanical strength assessments, including impact properties, are also necessary but will be influenced by the current state of the metal, particularly the extent of corrosion and pitting. Lastly, while ensuring that openings are adequately reinforced is critical for overall design integrity, without assessing the current condition of the plates first, these factors become secondary concerns.
