Expansion joint with alarm device

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.

Each expansion joint is tailor made. Layers of material are assembled on a frame which conforms exactly to the required profile. Bellows type expansion joints incl. or without reinforcing rings/frames. Diaphragms Expansion joints for varying cross sections and transitions. Construction from round to rectangular Construction according to drawings Non-standard high temperature seals Compound movement

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.

We produce expansion joints for all industrial sectors to take up vibrations, for noise absorption, or to compensate distortion by axial, lateral or angular movements. Our expansion joints are available in various versions and numerous elastomers variants in inner diameters from 25 mm to 1600 mm. Testing certificates of all well-known testing institutes are at hand. TYPE II Single or multiple flutes with rubber/fabric flange. Various elastomers qualities.
