Fabric expansion joint

rectangularflangeaxial

Overview
Fabric expansion joints are flexible compensators designed for gaseous media and aggressive environments. Constructed from high-performance materials, they operate under pressure or vacuum and provide multidirectional flexibility. Gas-tight options ensure reliable sealing across a wide temperature range.

Function and application
These expansion joints compensate thermal expansion, misalignment and mechanical vibration in ducting and piping systems. Typical uses include flue gas ducts, heat exchanger casings and industrial exhaust lines where vibration isolation and gas sealing are required.

Construction and materials
Manufactured in single-layer or multi-layer assemblies using technology-grade fabrics and sealing layers selected for temperature and chemical resistance. Designs may incorporate gas-tight membranes, reinforcement layers and protective coatings to extend service life under load.

Sizes and fastening
Dimensions, flange types and fastening arrangements are custom-made to customer specifications for integration with existing equipment and standard flanges.
