Product Description
High Temperature Fabric Expansion Joints with PTFE Seals for Screw Cooler Systems
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.
