Benefits

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.

  • Thicker wall of lens bellows holds up better to corrosion attacks
  • Weld repair can be performed by plant maintenance staff on thick walled bellows.
  • Drain couplings can be added to the bottom of the convolution to prevent condensate build up
  • Common use of carbon steel material
  • Thick walled, high convolution is durable and lasts for a long time.

Areas of Usage

  • Iron and Steel Industry
  • Mining Industry
  • Chemical Industry
  • Power Stations Cement Factories
