What area of the tank bottom requires special consideration for thick-film lining?

• A. The center because this is the area that will be subjected to the most stress
• B. The critical zone
• C. Any butt weld joints in the tank bottom
• D. The coving at the transition from the tank bottom to the shell

Answer: (D)

The area that requires special consideration for thick-film lining is at the coving transition from the tank bottom to the shell. This area is particularly vulnerable due to the geometry of the structure, where the flat surface of the tank bottom meets the vertical shell. This transition can be prone to stress concentration, corrosion, and other factors that may compromise the integrity of the tank. Implementing a thick-film lining in this region can help provide additional protection against these potential issues. The coving provides a smooth transition that minimizes sharp angles, which can lead to stress points and, subsequently, potential failure points in the tank. By applying an effective lining in this critical area, it enhances the overall durability and lifespan of the tank, addressing specific concerns associated with corrosion and the accumulation of moisture or chemicals. Understanding this context is essential for tank inspectors and operators, as neglecting to properly treat the coving area can lead to significant maintenance issues and environmental risks. Thus, ensuring that this particular area is lined adequately is a proactive measure in maintaining tank integrity.
