Technical Specifications

Design and Operating Principle

HeatFlex Fabric Expansion Joint designs are optimized to absorb thermal expansion and mechanical movements thanks to their high-temperature resistant multilayer fabric structure.

The compensator structure reduces mechanical stresses in duct and piping systems by absorbing thermal loads, vibrations, and duct movements caused by high-temperature gas flow.

Systems can be manufactured in circular or rectangular cross-sections and offer suitable solutions for different process and duct designs with flanged or frame-type connection options.

Thanks to its low-stiffness structure, it also contributes to damping vibrations at fan and equipment connections.
