Pre-assembled units

Pre-assembled expansion joint units consist of:

  • Fabric expansion joint
  • Metal frames/inner sleeves
  • Gasket (optional)
  • Fasteners

Frame material:
- Carbon steel
- Stainless steel
- Heat resistant steel

Pre-assembled expansion joint units can be supplied with surface treatment that is corrosion resistant (standard) and resistant to high temperatures. EagleBurgmann KE offers any RAL color code for the units. Units can be delivered with seaworthy packing or standard packing for road transportation.

eFlexgen

The main features of our new eFlexgen are lower emissions as well as increased robustness and performance. The multi-layer design that can withstand temperatures up to 575° C, have the ability to compensate for movements in all directions, and suitability for dry conditions. It can be delivered either as fabric only or as a preassembled unit. Additionally, it can be custom-made to fit the specific working conditions you have.

  • Up to 90% lower emissions
  • Improved safety
  • Longer lifetime
  • Saves energy in specific applications due to increased tightness
  • Verified by Bureau Veritas
