Standards und Freigaben

- EN 10204-2.2 certificate
- Safety Data Sheets (SDS) for individual materials


Fluastal expansion joints safely absorb thermal expansion and misalignments in pipe and duct systems in dry and high temperature area. Flexgen products compensate for movements in multiple directions simultaneously.


Pre-assembled units

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
