89-08: Design and Application of Composite Cooling Tower Couplings

This paper discusses the design and application of composite cooling tower couplings. Couplings are now available in both composite spacers and composite flexible elements. The composite spacers have proven their effectiveness through two years of service. The flexible coupling has been recently introduced after completing laboratory testing. The one-piece composite flexible element provides up to 5 degrees misalignment at a very low misalignment moment. The element also offers corrosion resistance, lightweight, and a virtually infinite fatigue life.
