What is a Bellows 2-Ply Stainless Steel Flex Exhaust?

EXHAUST BELLOWS

Most commonly, exhaust bellows are designed to limit the motion/kinetic energy within or passed along from the engine to high-cost emissions systems by absorbing displacements and vibrations and accommodating thermal expansion.

Applications

Exhaust bellows can be found On many Engines, Between Turbos, Between Turbo and Aftertreatment and even between Aftertreatment and the Silencer or Outlet Pipe for On- and off-highway commercial vehicle exhaust systems for:

  • Trucks
  • Construction
  • Marine
  • Buses
  • Forestry
  • Power Generation
  • Tractors
  • Mining
  • Military

Standard Bellows

The first and most common combination of features is what we like to call “Standard Bellows. Standard bellows offer excellent thermal expansion and vibration/motion control while meeting industry required leak specifications. They also deliver extremely long fatigue life if no torsional motion is present.

Features

  • Corrugated stainless steel body
  • Internal polylock liner (optional)
  • External braid (optional)
  • External mesh (optional)
  • Vibration damping mesh (optional)

Severe Duty Bellows

Severe Duty Bellows is the second sub-grouping of products and they are aimed at offering excellent durability in difficult applications. In addition this design combination reduces static loss and has superior thermal insulating properties when compared to standard bellows. The robust design withstands severe displacements and includes a braided exterior that protects the bellows from external damage.

Features

  • Corrugated stainless steel body
  • Internal polylock liner
  • External braid
  • Vibration damping mesh (optional)
