Expansion joints

Compensation by flexible connection

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.
