Metal Bellows for Aerospace Image Text

Metal Bellows Assemblies

Corrugated bellows combine higher pressure resistance with low spring rates and optimised expansion capacity. Small size steps for ideal interfacing from DN 2 to DN 100 and beyond, as well as from special materials (e.g. IN718 or Ti 15-3-3-3-3-3).

  • multi-plied designs for high flexibility with maximum pressure resistance
  • alternative designs/combinations (e.g. formed, edge welded, with / without braiding, coaxial)
  • diaphragm bellows with very high elasticity and low spring rates
