Suction and Discharge Joint are installed between bump on dredger and pipeline connector, which are convenient for installation and removal and to be functioned as reducing vibration and noise. The arch between the flanges ensures the flexibility of the expansion joint.
Flexible, 100% vacuum capability, Anti-wave, Wear-resistance, Weather-resistance, Aging-resistance, seawater resistance
The expansion joint also called bellow and compensater,it can subjected to movements. These movements can vary from very slow (thermal expansion or shrinking movements) to very fast (vibrations),also can be in all directions of axial,lateral and angular.
