What is the maximum allowable out-of-plumbness for a reconstructed tank?

• A. 1/30 of total tank height
• B. 1/50 of the total tank height
• C. 1/100 of the total tank height
• D. 1/200 of the total tank height

Answer: (C)

The maximum allowable out-of-plumbness for a reconstructed tank is specified as 1/100 of the total tank height. This standard is established to ensure the structural integrity and safety of the tank, preventing undue stress that could lead to failure or leaks. Out-of-plumbness refers to the deviation from vertical alignment, which is critical for tanks that hold liquids, as this misalignment can affect the distribution of weight and stress on the tank's shell and foundation. Allowing for a maximum of 1/100 of the total tank height provides a balance between ensuring structural safety and accommodating minor constructions inaccuracies that may occur during the reconstruction process. Setting this limit provides a guideline for inspectors and engineers to evaluate the condition of a tank post-reconstruction, ensuring that it meets safety and regulatory standards. If the out-of-plumbness exceeds this threshold, it may indicate underlying issues that could compromise the tank's operation and necessitate further evaluation or corrective measures.
