Fabric Expansion Joints have distinct advantages as they can accomodate relatively large movements and even some misalignment of flanges. They are also lightweight, easy to install and with the addition of internal insulation bolsters have good acoustic properties. Fabric expansion joints can be supplied fully assembled and fitted to support steelwork ready for insertion into ductwork. For retrofit applications, we can supply as factory joined or open for on-site joining where access is limited.

Expansion Joints are flexible mechanical elements, mainly existing of one or several metal bellows connected with flanges, weld or thread fittings on one or both ends. This may also include internal guide tubes, external protective sleeves, anchor ties etc. The primary applications of expansion joints are in piping systems and sanitary technology using them - to compensate pipe expansions and shrinkage due to temperature changes, - as elements to match non-aligned pipes, - to make pipe assembly easier, - to dampen vibration and noise. Either for axial movements either for lateral and angular movements HEITZ provide a wide range of proven, well-designed products. HEITZ offer expansion joints in a standard stock program as well as customer-specific expansion joints.
