Tubes and an HEX are supported by what?

Tubes and an HEX are supported by what?

• A. Baffles
• B. Frames
• C. Supports
• D. Mounts

Answer: (A)

In shell-and-tube heat exchangers, internal baffles serve as the structural spacers that hold and position the tubes as they pass through the shell. They keep the tubes evenly spaced, prevent sagging or vibration, and often provide attachment points that help secure the internal components of the exchanger. This is why baffles are what support both the tubes and the heat exchanger’s internal arrangement. Frames and mounts are external or overall support structures and don’t provide the direct internal support and alignment that baffles offer for tubes and the exchanger’s internals.
