Lens Bellows

Lens bellows can be the right solution to piping, ducting and vessel thermal growth problems compared to conventional thin walled metal bellows.

Thick-wall expansion joints are used primarily in heat exchangers and large diameter piping systems where thin-wall expansion joints would not be sufficient.

Advantages of Lens Bellows

Dents and gouges create stress risers in thin ply bellows which result in fatigue cracks over time. Lens bellows have the advantage of holding up to mechanical damage better than thin wall bellows.
