Exhaust Gas Expansion Elementes Image Text

Exhaust Expansion Joints

Exhaust Expansion Joints are used before, after or between the turbo chargers to compensate for heat expansions in the exhaust manifold or frontpipe area.

  • single or multiply bellows ensures a gas-tight solution
  • optionally with wire mesh ring as vibration damper
  • customised connections
  • available in all common connecting diameters

Expansion Element in the Manifold Area

Exhaust expansion elements are bellows that compensate thermal expansion, movements or installation tolerances. They are used in the manifold areas upstream, downstream or between the turbochargers.

  • single or multi-layer bellows ensures a gas-tight solution
  • optionally with wire mesh ring as vibration damper
  • customised connections
  • available in all common connecting diameters
  • optimally even at high temperatures and pressures
