What are tube ligaments?

Tube ligaments refer to the structural components found in a boiler, specifically in the context of the tube sheet. The area between the tube holes on the tube sheet is where these ligaments provide mechanical support and stability. This structural integrity is crucial for the safe and efficient operation of a boiler, as it helps maintain the alignment and prevents failures due to thermal expansion, pressure fluctuations, or mechanical stresses.

In boiler design, the tube sheet serves as a barrier between the combustion gases and the water in the tubes. Properly designed tube ligaments ensure that there is adequate strength to handle the forces at play without compromising the tube integrity, which could lead to leaks or catastrophic failures. Understanding the role of tube ligaments is important for engineers working with pressure vessels and heat exchangers, as it is essential for both safety and efficiency in boiler systems.
