Dredge Ball Joint
Application
Dredge ball joint is a flexible coupling between two pipes used to transport water and sand mixture from a cutter suction dredger or a trailing suction hopper dredger to the discharging area. Depends on the design of the dredge ball joint it can turn to all directions between 15 to 22.5 degrees. The purpose of a dredge ball joint is to accommodate the dynamic forces and movements that occur during dredging operations. Dredges are often used to remove sediment, silt, or other materials from the seabed, rivers, or lakes, and the ball joint helps in maintaining a continuous flow of material.
The dredge ball joint consist of at least five parts named casing, ball,gland,liner and seal. Pipe inner diameter from 300mm to 1200mm,turning angle 15 degrees and 18 degrees. This design enables the dredge pipeline to flex and adjust to changing conditions, such as variations in the seabed or the movement of the dredging vessel. It helps to minimize stress and strain on the pipeline, preventing damage and ensuring a more efficient dredging process.
