ASME tanks are usually bolted to?

The correct answer identifies that ASME (American Society of Mechanical Engineers) tanks are typically bolted to the frame for stability and support. Securing these tanks to a frame helps mitigate risks associated with movement, vibrations, and potential external forces that could impact the tank's integrity and operation. The frame acts as a structural base, allowing for safe positioning and alignment of the tank, while also ensuring that any weight distribution is adequately managed.

Other options, while they have their specific contexts, do not accurately reflect the typical practice regarding the installation of ASME tanks. For example, bolting tanks directly to the ground may not provide the same structural benefits and can lead to complications in maintenance or adjustments over time. Similarly, bolting to other tanks is not a standard or safe practice due to the varying weight loads and structural requirements. Finally, bolting directly to a concrete base may be common in some applications, but when specifically referring to ASME tanks, the frame is typically the more appropriate and recognized solution for mounting.
