Fabric Expansion Joints


Fabric expansion joints are highly flexible connections installed in pipe & ductwork as well as industrial items to compensate for expansion, resulting from heat or misalignment as well as vibrations as a result of mechanical and acoustical movements.

Fabric expansion joints are manufactured from high grade synthetic materials, elastomers and asbestos free fabrics. As a result of their superior flexibility, they can take axial, lateral, angular and torsion movements. Fabric expansion joints are mainly employed for gaseous media like air or clean gas or gas containing aggressive and abrasive as well as liquid matter.
