Dredge Ball Joints
Flexible pipeline connections that absorb movement while maintaining a secure seal. Essential for floating pipelines and dynamic dredging operations.
What is a Dredge Ball Joint?
A dredge ball joint is a specialized pipeline connection that allows angular movement between pipe sections while maintaining a pressure-tight seal. It consists of a ball and socket assembly with high-quality seals that accommodate the dynamic movements of floating pipelines.
Ball joints are essential components in dredging operations where pipelines must flex with wave action, tidal changes, and vessel movement. Without proper ball joints, rigid pipeline connections would experience excessive stress leading to fatigue failure and leaks.
Our ball joints are engineered for the demanding marine environment, featuring corrosion-resistant materials and long-lasting seals designed for continuous operation in saltwater conditions.
How Do Ball Joints Work?
A ball joint works on a simple but effective principle: a spherical ball rotates within a matching socket, allowing angular movement in any direction while the slurry continues to flow through the center passage.
High-quality rubber or polyurethane seals maintain pressure integrity throughout the full range of movement. The joint can articulate up to 17 degrees from center while handling the full operating pressure of the pipeline.
Ball Joint Size Range
We offer ball joints in a complete range of sizes to match your pipeline diameter requirements.
