Product Description
The high temperature fabric expansion joint is designed for thermal movement compensation, sealing, and vibration absorption in screw cooler systems, particularly in the soda, beverage, and food processing industries.
Manufactured by BSTFLEX, this expansion joint is fabricated from silicone rubber coated fiberglass glass fiber cloth combined with PTFE sealing elements, forming a flexible bellows structure capable of withstanding elevated temperatures and continuous operation.
The textile-based construction allows the expansion joint to absorb axial, lateral, and angular movements caused by thermal expansion while maintaining a reliable seal in air or gas conveying systems.
Woven glass fiber cloth
Non-combustible and heat resistant
Provides mechanical strength and dimensional stability
High temperature resistant and flexible
Protects fabric from moisture, dust, and abrasion
Suitable for dynamic movement and vibration
Excellent chemical and temperature resistance
Low friction surface
Enhances sealing performance and service life
Flexible textile expansion joint structure
Absorbs thermal expansion and mechanical vibration
Custom fabricated for specific duct or cooler geometry
This multi-layer construction ensures reliable performance in demanding industrial environments.
Compensates thermal expansion in screw cooler systems
Absorbs vibration and mechanical movement
Seals hot air or process gas flow
Protects connected equipment from stress
Supports stable operation in continuous processes
The expansion joint is designed for air and gas systems, not for liquid pressure piping.
