Non-metallic expansion joints are essential components in high-temperature duct systems where metal joints may fail due to thermal fatigue, corrosion, or excessive movement.
Vanox, a trusted fabric expansion joints manufacturer in Turkey, specializes in advanced non-metallic expansion joint solutions for severe industrial environments.
Why Use Non-Metallic Expansion Joints?
Non-metallic expansion joints offer superior flexibility and vibration absorption compared to metal alternatives. Their multi-layer fabric construction allows them to withstand extreme temperature variations while maintaining reliable sealing performance.
Material Structure
- Base fabrics: glass fiber, aramid, polyester
- Insulation layers: ceramic and silicate fabrics
- Coatings: PTFE, silicone, EPDM, neoprene
High Temperature Performance
Non-metallic expansion joints can operate continuously at temperatures up to 575°C and, with insulation or refractory lining, withstand temperatures up to 800°C. This makes them ideal for flue gas ducts, exhaust systems, and boiler connections.
Typical Applications
- Power plant ducting systems
- Industrial exhaust and ventilation lines
- Process gas pipelines
- Fan and turbine isolation points
By choosing Vanox non-metallic expansion joints, industrial operators benefit from long service life, reduced maintenance costs, and improved system reliability.
