DN400 Dredge Ball Joint

DN400 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 discharge area. The DN400 dredge ball joint is specifically manufactured to accommodate pipelines with a diameter of 400 millimeters. Its size and specifications are tailored to fit and connect pipes of that particular diameter. When procuring a DN400 dredge ball joint, it is essential to consider other technical parameters such as pressure rating, angular range, load capacity, material, sealing mechanism, and maintenance requirements, as these factors will determine the suitability and performance of the ball joint for the intended dredging application.
