- Coatings: Neoprene, EPDM, CSM, silicone, PTFE
These layers provide superior resistance to high temperatures, chemical attack, and mechanical stress, ensuring that the joints function reliably even in demanding applications.
Operating Parameters
- Temperature range: -35 °C to +575 °C (-31 °F to +1,067 °F), with optional insulation for higher temperatures up to 800 °C
- Pressure: -0.2 bar to 0.2 bar (-2.9 PSI to 2.9 PSI)
- Maximum movements: Axial up to 160 mm (6.5”), Lateral up to 80 mm (3”)
These specifications allow Vanox fabric expansion joints to safely compensate for thermal growth, mechanical movements, and misalignments in piping and duct systems while maintaining optimal performance.
Design and Configurations
Vanox fabric expansion joints are available in a variety of shapes and sizes to suit different installation requirements:
- Circular, oval, rectangular, or custom geometries
- Open or closed designs
