What are tube ligaments?

The correct answer is the area between tube holes on the tube sheet. Tube ligaments are critical components in the design of heat exchangers and boilers. They refer to the material that remains between the holes drilled in a tube sheet, which is where the tubes are installed. The integrity of these ligaments is essential because they help support the tubes and ensure that the pressure and heat exchange processes can occur effectively without compromising the structure.

Having a solid understanding of tube ligaments helps in recognizing their role in maintaining the efficiency and safety of thermal systems. If the ligaments are weak or compromised, it could lead to leaks or failures in the heat exchanger or boiler, emphasizing their importance in engineering applications.
