Engine Exhaust Bellows

It is placed on the engine before the turbo charger where high temperatures, vibrations and pressure impulses occur. Operating  Temperature up to 800 °C (1472 °F) and/or pressure up to 12 Bar (174 PSIG). The bellows, the flexible part of the expansion joint, is a multi-layer construction with thin layers of heat resistant stainless steel.

Bellows materials:

  • Austenitic Steel
  • Incoloys
  • Inconels
  • Hastelloys
  • Titanium
  • Other formable materials.

The expansion joint provides superior flexibility and is corrosion resistant in the aggressive exhaust gas applications. The expansion joints are designed with fixed or swivel flanges, pipe weld ends, ‘V’ flanges or other flange constructions made of stainless or carbon steel or other alloy materials. At high temperatures and flow velocities, sleeves are recommended. The sleeves protect the bellows from impact of particles.
