Pinned Truss

The Pinned Truss is assembled using threaded hardware, allowing the individual components (chords and struts) to be introduced through a vessel manway and installed within the mass transfer tower without welding.

• Components are designed to pass through the vessel manway
• No welding inside the column
  • Up to 80% reduction of installation time compared to field-welded solution
• Simple installation sequence reduces inspection requirements during installation 
• Interchangeable components
  • Improved maintenance/easy installation
• Minimized individual component weight 
  • Easier and safer handling
• High open area can be achieved
• Reduced shipping volume
