A ligament is a structural component in tube sheets or headers that provides spacing and support between adjacent tubes, ensuring proper alignment and mechanical integrity in heat exchangers and pressure vessels.
In industrial engineering, a ligament is a critical structural element found in tube sheets and headers of heat exchangers, boilers, and pressure vessels. It refers to the material section between adjacent tube holes, which maintains precise spacing, prevents tube vibration, and distributes mechanical loads. Ligaments are designed to withstand thermal expansion, pressure differentials, and corrosive environments while ensuring leak-proof tube-to-tube sheet joints. Their geometry and strength directly impact the equipment's efficiency, safety, and longevity.

Ligament efficiency is a design parameter representing the ratio of the ligament width (distance between adjacent tube holes) to the tube pitch. It indicates the structural strength of the tube sheet; higher efficiency (typically 40-60%) ensures better load distribution and resistance to pressure-induced stresses.
Ligaments maintain precise tube alignment, reduce vibration from fluid flow, and distribute thermal and mechanical loads evenly. This prevents stress concentration, fatigue cracking, and tube loosening, thereby extending equipment life and preventing leaks.
For corrosive environments, stainless steel (e.g., 316L), duplex steels, nickel alloys (e.g., Inconel), or titanium are preferred due to their high corrosion resistance. Material choice should match tube and shell materials to avoid galvanic corrosion.
