Expansion joints serve a crucial role in industrial ductwork by facilitating the controlled expansion and contraction of ducts. Their primary function is to accommodate thermal movements within the ductwork system. They mitigate thermally induced stresses by allowing thermal movements in a relatively unrestricted manner. Expansion joints contribute to the overall flexibility and structural integrity of the system which is essential in preventing the build-up of stress that could otherwise lead to damage in equipment, ductwork, and supporting structures.

The belt type is the preferred choice for large diameter ducts. Delivery available with insulation pre-installed for high temperature applications. Insulation depends on temperature level of the medium. Insulation is necessary to protect the expansion joint from abrasive media. Corners of rectangular expansion joint frames should be radiused. Delivered as open-end construction for site completion. The final splice will be made on site. The storage and installation instructions as well as the necessary adhesives are included with each shipment. Pre-assembled endless units are complete with appropriate steel components which may be in several parts depending on the size. KOREMA®’s “on-site service” is available for site supervision.

Penstocks are used to discharge the headwater from a reservoir. Due to thermal and dynamic effects on the pipelines which are usually run underground in the mountain, compensation for expansion is necessary. By fitting an expansion joint, slow creep movements, eccentricity, dilation and also pipe misalignment can be reliably absorbed. The MANOY® system seal WP, type 436, was specially developed for leakagefree operation of an expansion joint.
